Interview with Peter Rovekamp, 

VP - Waldom Electronics EMEA 

Recent times seemed to be marked by pessimism for the future. The largest economy in the world in a state of 

turmoil, a disunited EU and a pandemic that seems to hold us in its grip forever. On the other hand, there have 

always been economic challenges, but they have also brought us new insights, innovations and ways of working. 

Rethinking things, satisfying new needs and even creating new ones are challenges that Bürklin Elektronik are 

rising to meet. 

Early on, Bürklin Elektronik carefully selected and continuously expanded its range of products in the fields of 

health technology and industrial automation technology. These are markets which enjoy a very high level of 

attention, not only in the current circumstances, and which will also grow in the long term. With our strong 

partners, we can serve these segments extensively and provide expertise. Even now, we and our partners stand 

for quality. This is a very important factor, especially when it comes to the all-important reliability in health 

technology. 

We at Bürklin Elektronik take a sportingly realistic view of the future, because complex issues are our daily 

business. We support you in the present time with high availability and comprehensive advice also on the topics 

of health technology and industrial automation - we are happy to be there for you. 

Furthermore, we look forward to welcoming you at this year‘s AAA Chemnitz on 22 + 23 Sept 21 and AAA Essen on 

27 + 28 Oct 21. Come by our stand and see our services for yourself.

PROJECT PROGRESS 

AND INSIGHTS 

SMART BÜRKLIN 

ONLINE SHOP 

TO INCREASE ITS DIGITAL PRESENCE AND IMPROVE THE BUYING EXPERIENCE FOR ITS CUSTOMERS, 

BÜRKLIN ELEKTRONIK IS INVESTING IN A NEW HIGH-PERFORMANCE ONLINE SHOP. 

As already reported in the Bürklin 

Elektronik Quarterly # 01/2021, 

Bürklin Elektronik has decided on 

a successful technology change. 

Together with its implementation 

partners, Bürklin Elektronik is pushing 

ahead with a successful go-live 

of the Smart Bürklin Onlineshop 

this year. In this Bürklin Elektronik 

Quarterly # 02/2021, we would also 

like to inform you - dear customers 

and suppliers - about the progress 

and provide insights into the current 

project events. 

INTEGRATION 

OF INTELLIGENT SEARCH 

feedback from the current online 

shop. 

EASY SELECTION FROM 

A COMPLEX RANGE 

The Bürklin Elektronik online shop 

will continue to offer its customers 

the entire range of products related 

to electronics: around 500,000 

products from over 500 well-known 

manufacturers are just a click away. 

The bright, modern and consistent 

design in the style of the Bürklin 

Elektronik corporate identity forms 

the basis for excellent usability and 

intuitive orientation.. 

Easy selection from a complex range:

Smart Bürklin Online Shop 

at Bürklin Elektronik 

The ‘Smart Search‘ system is an 

integration of Intershop with the search 

software Elasticsearch. It is an 

alternative to the standard Intershop 

search based on Solr. Smart Search 

enables our customers to find the 

perfect, non-trivial orientation in our 

assortment of products related to 

electronics. The features of ‘Smart 

Search‘ - as Results Highlighting and 

Spell Checking- will be the core of 

the premium search function which 

the result ‘understands‘ the customer. 

The programming of the search 

and its functions is a continuous 

development process, based among 

other things on facts and figures of 

our customers‘ search entries and 

continuously considering customer

THE CUSTOMER 

IS OUR FOCUS 

Our customers are at the centre of 

the new online shop. To best meet 

their wishes in terms of user-friendliness, 

orientation, and range of 

functions, we have strongly incorporated 

previous customer feedback 

into the development. To be able to 

put this to the test in advance, we 

will carry out a comprehensive pilot 

and test phase before Go-Live. Every 

day, we at Bürklin Elektronik work on 

continuously optimizing and further 

developing our online shop, both 

functionally and technically, based 

on our customer requirements and 

needs. Our top priority is to present 

a new online shop that satisfies our 

customers from day one. This is our 

claim, and we are currently working 

on it. 

As part of a comprehensive marketing 

concept, which will accompany 

the time before and after Go-Live in 

particular, we will inform our customers 

and suppliers in good time via 

the known channels about when our 

new online shop will be launched in 

the new design and with the promised 

added values. 

Since your opinion is especially 

important to us, we would be pleased 

if you would share your ideas and 

expectations of a successful Bürklin 

Elektronik online store with us. 

Contact our customer service at info@ 

buerklin.com and help us to make our 

new online store even more customer-friendly 

and in line with your 

requirements. 

THE DIGITAL CUSTOMER ACCOUNT PROVIDES COMPREHENSIVE FUNCTIONALITY 

- Access to the order history 

of all orders placed offline 

as well as online 

- Insight into the current order 

status with shipment tracking 

- Management of price inquiries 

& direct transfer option to orders 

- Maintenance of Master data 

- Management of watch lists 

& order templates

INTERFACES 

IN SALES AND PROCUREMENT 

E-SALES AND 

E-PROCUREMENT 

WHAT‘S THE STORY BEHIND IT, AND DOES IT MAKE SENSE TO SEPARATE THEM? 

At Bürklin Elektronik, we actually 

only ever talk about e-procurement 

connections - but we actually mean 

both connections in the sales area 

and in procurement. However, since 

purchasing is optimized in each 

case - but from different perspectives 

- we have decided to use the 

term e-procurement rather than an 

additional e-sales area. In addition, 

in the worst-case scenario, a hard 

separation bears the risk that one 

area is fully busy while the other 

area is idle and could actually take 

over things. 

For this article and an overview of 

the individual tasks, however, we 

would like to retain this distinction 

as an exception. 

E-SALES 

In customer direction, we at Bürklin 

Elektronik offer several different 

tools and interfaces to improve the 

purchasing experience. These include 

procurement platforms, BMEcat, 

OCI, API and EDI. Since these have 

already been examined and covered 

in detail in the Bürklin Elektronik 

Quarterly edition # 04/2020, we will 

refrain from looking at them in detail 

again. 

In the case of procurement platforms, 

which are used by many 

customers to relieve their own 

purchasing departments, there are 

many ways to provide them with the 

necessary product data. 

We offer here the BMEcat, a static 

catalog, with a firmly defined assortment 

and negotiated prices. This 

catalog can be searched via the 

platform with various search options 

and also with the help of filters, and 

the required products can be transferred 

into an order. 

Another possibility is offered by 

various interfaces to the online store, 

which can also be integrated via a 

procurement platform or directly 

into the ERP. A distinction is made 

here between OCI - an interface with 

which the interface of the online 

store can be used normally - and API, 

in which the article search is carried 

out by a third-party system and 

the store interface is not used. The 

advantage is that the most current 

data of the supplier‘s store can be 

accessed directly and prices and 

availability can be checked. 

Electronic Data Interchange (EDI) 

offers the customer the possibility to 

send the order generated with the 

aforementioned technologies to us 

electronically. This offers both sides 

many advantages in terms of speed 

of processing, as well as process 

reliability. Both are increased by EDI. 

In addition, manual work such as 

typing orders or order confirmations 

is eliminated. 



9

E-PROCUREMENT 

In our purchasing department, you 

currently only find electronic data 

interchange - but increasingly so - in 

order to optimize and streamline 

purchasing processes. There are 

various reasons for this. The most 

important reason is that we have 

fixed suppliers for all products - sometimes 

several per product - stored 

in our material master. This makes 

the search for suitable articles or 

suppliers for certain articles mostly 

superfluous. 

A specific feature here is our special 

purchasing department, which takes 

care of finding suitable suppliers for 

special product requests from our 

customers. For this department, the 

connectivity options that we already 

Von: ROBERT MATTHEUS 

E-Procurement Manager 

at Bürklin Elektronikk 

CONCLUSION . 

provide to our customers would 

certainly also be useful and would 

probably make the work easier. 

Should new technology be introduced 

here in the future, you will of course 

be informed again in your Bürklin 

Elektronik Quarterly. 

As already mentioned, our purchasing 

department particularly benefits 

from a working EDI connection to as 

many suppliers and manufacturers 

as possible. Since many partners 

usually order several items on an 

almost daily basis, it is an important 

support for both sides if manual processes 

are eliminated. This means 

that our suppliers do not have to type 

out paper or PDF orders, which saves 

time and also means active 

In conclusion, it remains to be said 

that both our customers and we 

ourselves, as well as our suppliers, 

can benefit from the different technologies 

we offer. There are advantages 

for both partners involved and an 

optimization of existing processes. 

Both sides are therefore equally 

important and must not be neglected. 

A temporary focus on a specific 

(sub-) area can make sense, whereas 

a complete separation into e-sales 

and e-procurement would not make 

sense, at least not today at Bürklin 

Elektronik. The main reason for this 

is that in both areas the main focus 

is on EDI connections, which can be 

time-consuming to implement in 

some cases, while the other 

error prevention. As a result, we 

also receive the ordered goods more 

quickly and, above all, the right goods 

in the correct quantity. Thanks to the 

automated import of order confirmations 

on our side, our colleagues in 

purchasing have more time for the 

really important things - price negotiations 

and delivery date queries. In 

addition, the confirmed delivery dates 

are also visible more quickly in the 

online store and for our sales department. 

Ultimately, all our customers 

benefit from this. 

technologies are implemented 

comparatively quickly. Due to the 

ultimately remaining distinction in 

EDI connection to a customer or a 

supplier, which also only corresponds 

to the different perspectives 

mentioned at the beginning, a hard 

distinction does not make sense 

here. This means that our team can 

always work more intensively where 

there is the biggest need, without 

being prevented from doing so by 

hard boundaries. In other companies, 

however, this can be quite different, 

of course.

RAFI 

SIMPLE OPERATION 

AND SIGNALING 

WITH IO-LINK 

With new variants of its outdoor-capable E-BOX control units and TILTED DIAMOND+ signal lamps, 

RAFI is now offering two innovative IO-Link product families which are particularly easy to parameterize 

via the sensor/actuator interface and can be linked into any automation network as required. 

Despite initial skepticism in the automation industry, 

IO-Link was soon rapidly distributed among machine 

and plant manufacturers after its market launch in 2009. 

Since then, this sensor/actuator interface has enjoyed 

an uninterrupted success story. Because IO-Link – the 

intuitive brand name for the “Single-drop digital communication 

interface for small sensors and actuators” 

standardized in the IEC standard 61131-9 – is not just 

the first standardized system in the world for sensor/ 

actuator communication, but also exclusively uses 

well known, tried and trusted connection technology: 

An IO-Link system is based on an IO-Link master and 

IO-Link devices as well as actuators and binary/analog 

sensors, which are linked up or connected via unshielded 

standard 3-wire cables as well as M12 or M8 plugs. In 

addition to that, measurement, diagnostic, and process 

data can be transmitted between the control and process 

levels without additional cabling, as today, all established 

fieldbuses have an integrated IO-Link gateway. In 

addition to that, storing all IO-Link device parameters in 

the IO-Link master makes it all much easier to service, 

as there is no need for renewed parameterization after 

a device replacement: The IO-Link master automatically 

recognizes the connected devices by their ID and independently 

transfers the device-specific parameterization 

data. However, the simplicity and efficiency of IO-Link not 

only benefits engineers and users, but also the quality of 

a wide variety of manufacturing procedures or processes 

and thus practically the entire automation industry. Due 

to its low implementation effort, IO-Link also enables 

sensor-based control of processes where it was previously 

not possible for cost reasons. 

E-BOX IO-LINK: The decentralized control unit for 

simple control tasks with an IO-Link interface 

With two innovative product families, RAFI also makes 

use of the benefits of the IO-Link interface facilitating 

particularly simple network integration and device configuration: 

The HMI specialist is using the E-BOX IO-LINK 

to provide a new version of its outdoor-capable control 

box, which allows decentralized management of simple 

control tasks and can be integrated into any fieldbus via 

its IO-Link interface. Using the M12 terminal, the control 

unit which is combined in the extremely slimline IP65 

housing with the two illuminated pushbuttons from the 

control device program RAFIX 22 FS+ can also easily 

be installed and operated by untrained personnel. The 

IO-Link device identification prevents installation errors 

because incorrectly installed devices are reported to the 

control unit. Thanks to integrated MICON 5 tactile switches, 

the illuminated pushbuttons of the E-BOX provide 

excellent tactile feedback and can be remotely customized 

via IO-Link with a wide range of functions. These 

include night mode with various brightness levels and 

a flexible choice of illumination colors in five standard 

or three individually adjustable RGB colors from a color 

palette with 16 million different colors. The pushbuttons 

can also be configured with four different flashing 

modes for different applications. The versatile range of 

options available for parameterization of button colors, 

brightness, and flashing modes make stock management 

easier as the E-BOX IO-LINK can simply be configured 

via the control for different requirements. For custom 

legending of the pushbuttons, RAFI supplies FLEXLAB 

legending sheets either pre-printed or blank. With their 

compact dimensions of 123.2 mm x 40 mm x 35.6 mm, 

the control units are ideally suited for installation on 

40 mm wide profile rails on production lines or safety 

fences. A fixing clip that the E-BOX simply clips onto is 

included in the scope of delivery for attaching to profile 

rail grooves and flat mounting surfaces. 

TILTED DIAMOND+ IO-LINK: A wide variety of signal 

effects in a sophisticated design with IO-Link interface 

Alongside the new E-BOX, RAFI is also introducing an IO- 

LINK version of its LED signal lamps in the TILTED DIA- 

MOND+ series onto the market, which allows very simple 

and quick set-up thanks to the M12 terminal and IO-Link 

parameterization. Apart from night settings and lighting 

colors of your RGB-LEDs that can be freely configured, 

the TILTED DIAMOND+ IO-LINK offers eight different 

flashing modes that can be used to notify you of specific 

alarms or machine states, for example with single 

flashes, continuous flashing, or pulsating light. What 

distinguishes the signal lamps with IP66 rated protection 

are exceptional brightness, vibration resistance, no 

need for maintenance, and the striking dome-shaped 

bezel design. The diamond-shaped lenses arrayed 

all round give the bezels excellent illumination, 

clear signal colors, and top visibility over great 

distances. Apart from a mounting base, the 

accessories available include support tubes in 

various lengths and shapes.

SCHURTER 

SAFE TECHNOLOGY 

HELPS SAVING LIVES 

SCHURTER DG12: IEC C14 appliance inlet with 

mains filter, TA35 circuit breaker, V-Lock cord 

retention and optional cover for IP67. 

Available as Medical Version (M80). 

The new corona virus SARS-CoV-2 has been raging since January 2020, spreading at an unprecedented pace, 

exhibiting insidious properties and puzzling experts. SCHURTER has been classified as a system-relevant 

company and is supporting the fight against the pandemic by significantly expanding the production of 

components and input systems for medical equipment. 

After the epidemics SARS (2002) and 

MERS (2012), which were also caused 

by corona viruses, some Asian countries 

appeared to be well prepared. 

The West, on the other hand, which 

had hardly been affected by both previous 

epidemics, was literally overrun 

by the new SARS-CoV-2. 

Thanks to decades of expertise in 

manufacturing as a supplier of medical 

technology, SCHURTER was able 

to avert the lockdown of many of its 

production facilities. Pandemic and 

system-relevant plants were closed 

in very few countries. 

Applications 

It quickly became evident that the 

capacities of respirators would not be 

sufficient in the event of an unchecked 

outbreak of the virus. Analysis 

systems for blood samples are of vital 

importance for assessing the situation 

during the crisis. These were not 

Control panel for a top class modular ventilator 

available in sufficient numbers. For 

many years, SCHURTER has been 

working closely in these areas with 

the most important and renowned 

manufacturers of respiratory equipment 

and blood analysis devices. 

Also, the disinfection equipment 

division (UV-C) has been added. 

Human Machine Interface 

Highly complex equipment such as 

ventilators can only be operated by 

qualified specialists. A ventilator can 

be described as a human-machine 

system. This refers to a system in 

which a mutual exchange of information 

between man and machine 

takes place. This communication 

takes place via a Human Machine 

Interface (HMI). The interface is therefore 

essential for the translation 

and transfer of information between 

the two coupled systems man and 

machine. 

The following points should primarily 

be mentioned here: intuitive operability 

through few, clearly recognizable 

input options; clear feedback from 

the interface that an input has been 

correctly recognized; information 

presentation in accordance with 

human receptivity. 

Touch panel solutions from SCHUR- 

TER are qualified for medical applications 

and comply with the relevant 

medical standards. SCHURTER has 

acquired enormous know-how in the 

field of touchscreens for medical devices 

and supplies the world‘s most 

renowned manufacturers. 

Switches by no means obsolete 

Usually not all functions of hightech 

medical devices are triggered 

via touchpanel. Switches are just 

as important. Similar demands are 

placed on them: first-class feedback 

and absolute reliability. For this task, 

SCHURTER offers a broad portfolio 

of high quality metal line switches in 

different technologies (mechanical, 

piezoelectric, capacitive) and dimensions. 

Safe power supply 

Safety in medical devices begins 

with the power supply. No electrical 

device in medical technology may endanger 

patients or staff. This requires 

appropriate protective measures. 

Device plugs and power entry modules 

(PEM) with or without line filters 

must comply with the medical device 

standard IEC/UL 60601. SCHURTER 

offers a wide range for this purpose. 

Medical power entry modules (M5 

or M80) usually consist of the following 

components: an IEC appliance 

inlet with optional cord retention 

protection, a fuse holder accessible 

from outside, a power switch and an 

(optional) mains filter. Various power 

entry modules are also waterproof. 

The mains filter is an important 

safety element. It protects the device 

from external RF interference and 

reduces potentially disturbing emissions. 

V-Lock cord retention 

Blackouts occur rather rarely in the 

industrialized world. But a power cut 

does not always have to come from 

the energy suppliers. Sometimes just 

a small mishap is enough. Carelessness 

may cause you to pull on 

the wrong cable, or you may step on 

the wrong cable - which shouldn‘t 

be there. In medical technology, you 

simply can‘t afford such a thing. This 

does not only apply to the operating 

theatre, but also to all life-support 

and life-monitoring systems. It would 

be fatal if a device suddenly stopped 

working. SCHURTER relies here 

on the V-Lock cord retention safety 

device. 

Saving lives with know-how 

Thanks to many years of experience 

and in-depth know-how in safe 

power supply and customized input 

systems, SCHURTER can contribute 

to the recovery of seriously affected 

patients and help save lives in emergency 

situations such as the current 

COVID 19 pandemic. 

Company 

The SCHURTER Group is a globally 

successful Swiss family business. 

With our components ensuring the 

clean and safe supply of power, input 

systems for ease of use and sophisticated 

overall solutions, we impress 

our customers with agility and excellent 

product and service quality. We 

focus on industrial equipment, medical 

equipment, automotive, avionics 

and space, data and communication 

and energy.

WAGO 

CONNECT ALL CONDUCTOR 

TYPES WITHOUT TOOLS – 

AT ONCE 

WAGO DEBUTS THE LEVER-EQUIPPED 221 SERIES 

INLINE SPLICING CONNECTOR FOR UNIVERSAL CONDUCTOR 

TERMINATION IN THE FEEDTHROUGH DIRECTION. 

A truly standard-setting 

conductor connection for 

all conductor types from 

0.2 to 4 mm², WAGO’s new 

lever-equipped 221 Series 

Inline Splicing Connector 

offers unsurpassed simplicity, 

speed and reliability. 

The WAGO Inline Splicing 

Connector combines all 

the familiar advantages 

of the 221 Series Splicing 

Connectors into a slim 

design. It allows universal 

conductor connection – 

with lever technology that 

completely eliminates tools 

– and provides a visibly 

secure conductor contact. 

Where multiple poles are 

required, additional adapters 

give users the freedom 

of a highly modular and 

flexible setup of up to five 

fixed-position poles in one 

adapter – whether it‘s with 

or without strain relief, on 

DIN-rails with a snap-in 

mounting foot, for screw 

mounting, adhesive mounting, 

tie-on mounting or 

suspended mounting. 

Two variants of the inline 

splicing connector are 

available, both with EN and 

UL approvals: one version 

has a transparent cover for 

conductor cross sections 

from 0.2 to 4 mm² for all 

standard applications. The 

other version uses a white 

cover (favored in North 

America) for the extended 

connection range with 

AWG-12 conductors. 

Universal Connection 

Technology for Installation 

in Tight Spaces 

As a universal connection 

technology, the 221 Series 

Inline Splicing Connector’s 

compact dimensions not 

only improves a firm’s 

existing installations, the 

small footprint also opens 

up a wide variety of new 

applications. These include 

space-restricted applications 

like laboratory and 

test setups, production test 

bays, lighting connection 

in suspended ceilings, extending 

loudspeaker cables 

and distribution boxes in 

industrial applications. And 

those are just the tip of the 

iceberg – the small design 

unlocks tremendous 

opportunities. Those are 

just some of the possible 

uses that could benefit 

from the 221 Series Inline 

Splicing Connector. 

Quick and Easy-to-Use 

with Secure Conductor 

Contact 

The WAGO 221 Inline 

Splicing Connector makes 

connecting solid, stranded 

and fine-stranded conductors 

in the feedthrough 

direction intuitive and 

convenient. The WAGO 

lever streamlines usage: 

raise the lever, insert the 

conductor, lower the lever. 

Disconnecting conductors 

is just as quick and easy: 

raise the lever, remove the 

conductor, lower the lever. 

Thus, all conductor types 

can be connected without 

using tools. Packaging 

WAGO’s industry-proven 

spring pressure connection 

technology into a compact, 

transparent housing 

ensures a visibly secure 

contact of all conductor 

types with cross-sections 

from 0.2 to 4 mm². 

Multiple Poles with 

Marking – Customizable 

with the Adapter 

WAGO’s 221 Series Inline 

Splicing Connectors also 

allow the implementation 

of multiple poles. Up 

to five modules can be 

latched into corresponding 

adapters, and these can 

be expanded even further 

with additional adapters if 

necessary. Fixed-position 

installation of the adapters 

is possible on a DIN-rail, 

with or without strain 

relief based on application 

needs. The adapters 

can be secured with a 

latching mechanism, screw 

mounting, adhesive mounting, 

tie-on mounting or 

suspended mounting. The 

provided marking surface 

is pre-marked and can be 

customized with adhesive 

strips for clarity.

BULGIN 

MEDICAL APPLICATIONS 

AND THE NEED FOR 

THE RIGHT ELECTRICAL 

COMPONENTS 

Current medical devices enable the prevention and treatment of diseases through diagnosis, early 

detection and treatment. As the world population deals with a pandemic caused by the novel coronavirus, 

the availability and reliability of healthcare facilities has become an important feature. Medical equipment 

for ventilation, imaging, ultrasound examinations, monitoring are important tools of healthcare. 

Use of electronic components in 

medical devices 

Electronic and electromechanical 

components must fulfil specific 

properties and attributes in order 

to be used in medical technology. 

The important characteristics for 

electrical components that must be 

taken into account in the development 

of medical devices are listed 

below. 

1. protection class (IP): Fully 

waterproof and dustproof connectors 

with an IP rating of IP68 or IP69K are 

required for this application. Connectors 

with this IP class can guarantee 

a reliable connection even when 

immersed in liquid for more than 

30 minutes. 

2. connect and disconnect: Connectors 

should connect easily and 

reliably. The contacts can be dimesioned 

accordingly, depending on 

whether the cable needs to transmit 

data or power. As medical equipment 

is used by changing medical staff, it 

is important to have connectors that 

are self-explanatory and thus easily 

mated and disconnected. 

3. mating cycles and secure connection: 

Ideally, connectors used in 

medical devices must experience a 

high number of mating cycles. The 

number of mating cycles a connector 

provides is the measure of its 

longevity throughout its life cycle. 

Connectors with mating cycles in the 

range of >1000 are preferred for use 

in medical devices. 

4. connections to a computer: Many 

medical devices, such as the ultrasound 

machine and other patient 

monitoring systems, need to be 

connected to a computer. D-sub or 

USB connectors are usually used 

for this purpose. Threaded screwin 

connectors are a good option for 

these requirements. 

5. voltage connection considerations: 

connectors that are screwed 

tight are preferable to push-pull 

connectors, which are held in place 

by friction pressure, for use in high 

voltage applications. 

6. interoperability or interconnectivity 

within the same product line 

or standard: The interoperability of 

connectors is an important feature 

in the use of peripheral devices and 

applicators, such as ultrasound 

probes or other portable application 

parts. Since push-pull connectors 

often have very specific connection 

requirements, connector interoperability 

must be considered. 

7. safety considerations: The safety 

of medical devices is of paramount 

importance as they are used in close 

proximity to patients. Therefore, well 

insulated cables, connectors and 

applied parts / applicators are required. 

Connections must be reliable so 

as not to cause unexpected loss of 

connection or patient hazard. 

8. disposable use / items: Some 

medical devices may use disposable 

applicators / application parts. For 

reasons of hygiene and safety, these 

are used with disposable connectors. 

In such cases PVC connectors are 

suitable, which are inexpensive and 

can be disposed of after each use. 

9. use of cables in the medical 

industry: The general rule is that the 

cable assemblies used must be safe 

for both the operator and the patients. 

In many cases, overmoulded 

cables are preferred. They reduce 

the risk of cables being subjected to 

tension or torsion to fail electrically 

prematurely. As a result, overmoulding 

prevents electromagnetic 

interference.

WIHA 

CONTROLLED POWER 

AND MORE RELIABILITY 

WITH TORQUE TOOLS 

THE RIGHT TWIST 

FOR PROCESS SAFETY 

In modern industrial and 

production units today, process 

safety is one of the top 

objectives. Usually, various 

staff members are involved 

in one and the same 

process in today‘s standard 

shift model. In terms of 

process safety, very normal 

human „differences“ in the 

application of force during 

a fastening process must 

be avoided. Volker Lehmann, 

product manager 

and torque specialist at 

Wiha explains: “Ensuring 

process safety and material 

protection at the same 

time requires using the 

correct hand tools with the 

appropriate torque for the 

application at hand. This 

prevents interruptions to 

the production process or 

quality problems. The aim 

of „controlled fastening 

torque“ is to prevent high 

costs of reworking or production 

recall for the users 

and to avoid damaging the 

manufacturer‘s own quality 

image.“ 

Compliance with the 

correct torque is also very 

important for electricians, 

for example. Different 

fastening tasks and processes 

require different 

torque settings. The size, 

type, quality and material 

of the screws all play a 

role. The same applies to 

the type and quality of the 

work piece, the equipment, 

or the material into which 

the screw is inserted. 

Manufacturers usually 

provide very precise specifications 

as it can hardly 

be expected of the user to 

spontaneously determine 

all factors on locations. 

Reworking and damages to 

the material are just some 

of the consequences that 

may result from the lack 

of compliance. To provide 

a form of “insurance” in 

case of negative repercussions, 

the proof of the use 

of the correct torque tools 

should essentially be a key 

requirement for every type 

of company. Based on the 

great variety of manufacturers‘ 

specifications, equipment, 

and fastening tasks, 

flexibility is an additional 

criteria for tools. 

Wiha offers user-oriented 

solutions that not only 

ensure process safety and 

efficient working, but also 

place importance on safety 

and health-related factors. 

As one of the first suppliers 

of modern torque fastening 

tools, Wiha translates its 

many years of experience 

and deep-rooted expertise 

into its wide range of 

torque fastening tools. Its 

variable torque systems, 

screwdrivers in the TorqueVario®-S 

and iTorque 

ranges, and T-handles from 

the TorqueVario®-STplus 

range, com-bine precision 

and functionality with safety 

and ergonomics. Depending 

on the application field, 

different torque hand tools 

with various features and 

advantages are offered, 

for example, VDE or ESD 

designs. 

Most recently, the 

e-screwdrivers speedE® II 

electric in combination with 

the Wiha easyTorque torque 

adaptors are also part 

of the flexibly applicable 

torque family with insulated 

slimBits from Wiha.

KNIPEX 

CABLE 

STRIPPING 

Cable stripping is one of the most fundamental and important tasks in electrical installation. 

The term stripping is used to describe two different procedures. First, it indicates the removal 

of the outer sheath of the cable, exposing the individual wires. Second, the term is used when 

the insulating layer is removed from the individual wires. 

It all comes down 

to the tool 

If you want to strip the 

insulation efficiently, thoroughly 

and comfortably, you 

should make sure to use 

the right tools. Otherwise 

there is a risk of damaging 

the inner core. If only a 

knife is used instead of 

a suitable wire stripper, 

this can cut off the wire 

strands. This reduces the 

cross-section, which can 

result in contact resistance 

and possibly even electrical 

fires. Modern wire strippers 

deliver the best possible 

results because they cut 

the insulation down as far 

as the wire strands. 

There are a few things to 

keep in mind during the 

stripping process. The 

cross-section of the cables 

and lines as well as their 

material properties are 

decisive when choosing the 

right wire stripper. 

All types of cables 

firmly under control 

The advantage of the KNI- 

PEX PreciStrip16 is that it 

is universally suitable for 

both fine and solid core 

cables, as well as flexible 

cables. With a capacity 

range from 0.08 to 16 mm², 

the PreciStrip covers a wide 

range of cross-sections, 

which makes it very versatile. 

Thanks to the precise 

adjustment, it can strip 

cables within the large capacity 

range automatically, 

even where traditional automatic 

devices often fail. 

Many automatic insulation 

strippers fail when they 

encounter special insulating 

materials, such as 

particularly soft insulating 

materials or when working 

in extreme heat or cold. In 

order to further enlarge 

the area of application of 

the KNIPEX PreciStrip16, 

it can be flexibly pre-set 

for such special conditions 

with an adjustment wheel 

with tactile locking positions. 

The high-tech wire 

stripper consists of parabolic 

stripping blades that 

separate insulation from 

both extremely fine-stranded 

and solid round cables, 

then automatically strip it 

off backwards. The pair of 

blades largely encloses the 

insulation and is therefore 

suitable for many flexible 

materials. 

Wire stripping in solar 

panel installations 

These days there are specific 

insulation requirements 

in many different areas 

that have to be considered. 

One of these areas is solar 

energy and the associated 

solar panel installations. 

The insulation materials 

used in the development of 

solar cables are particularly 

tough and hard. Stripping 

solar cables involves 

removing almost all the 

material. The KNIPEX 12 12 

11 wire stripper was specially 

developed to precisely 

meet these demanding 

requirements for the stripping 

process. Two pairs of 

blades cut the insulation on 

the cable around the entire 

circumference. In this case, 

the blades are shaped and 

ground so that the cut is 

made very close to the conductor. 

After cutting, one 

of the two pairs of blades 

stops and holds the severed 

insulation in place. 

The other pair of blades 

strips the insulation from 

the cable. 

The precision insulation 

strippers have a length 

stop for even stripping 

results. It can be easily 

moved and adjusted by 

squeezing it with your 

fingers. This ensures that 

the stripping results, even 

of challenging insulation 

materials, meet the high 

demands in terms of consistent 

quality. 

These wire strippers make 

work significantly easier. 

After inserting the solar 

cable, the entire stripping 

process takes place with 

a simple squeeze of the 

hand, as if by itself. Difficult 

to process insulation 

materials are removed 

precisely and reliably 

thanks to the length stop: 

this represents a gain 

in time and quality for 

companies and installers, 

especially when it comes 

to solar panel installations. 

High operating comfort 

for enduring work 

The ergonomics of the 

tools used is gaining 

increasing importance, 

especially in more complex 

and time-consuming 

stripping processes. 

KNIPEX wire strippers 

have an ergonomic 

two-component handle 

that ensures comfortable 

handling throughout the 

day. The weight of the wire 

strippers also plays a role. 

In order to be able to work 

consistently and accurately, 

every gram counts 

for the user. This is the 

reason why the KNIPEX 

PreciStrip16 really stands 

out. With a weight of 180 

g and the ergonomic 

two-component handle, it 

fits securely and comfortably 

in the hand and can 

also be used comfortably 

over long periods.

WALDOM IS FOCUSED 

ON A MODEL OF 

ONLY SELLING TO 

B2B DISTRIBUTION 

COMPANIES 

Waldom and Bürklin Elektronik, 

both family-owned companies 

and on the market for more 

than 60 years, are linked by a 

successful cooperation. 

Peter Rovekamp, Vice President 

EMEA at Waldom, outlines the 

manufacturer‘s strategy and 

takes a look into the future 

PETER ROVEKAMP 

VP - Waldom Electronics EMEA 

Mr. Rovekamp, Bürklin Elektronik 

and Waldom have been working 

together profitably for six years – 

why do we fit together so well? 

Peter Rovekamp: Waldom was 

introduced to Bürklin Elektronik by 

TE Connectivity over 6 years ago and 

the relationship has developed into 

a key strategic relationship for both 

parties. Both companies work closely 

together to join strengths in tackling 

the challenges and opportunities the 

electronic component industry has 

to offer. And with the joint entrepreneurial 

spirit that rests deeply within 

the DNA of both companies drives 

continued success in adding more 

value to Bürklin Elektronik customer 

base. Today Waldom is working together 

with Bürklin Elektronik across 

seven electronic component supplier 

brands, with TE Connectivity being 

the leading one. 

Asked from family business to 

family business: What are Waldom 

Electronics’ goals and on what 

based Waldom Electronics’ Success 

over the last years? 

Peter Rovekamp: Waldom Electronics, 

a family owned company 

as Bürklin Elektronik, with over 60 

years history is focused on a model 

of only selling to B2B distribution 

companies. Waldom builds strategic 

relationships with Suppliers and Distributors, 

solving their supply chain 

challenges through our innovative

programs. These programs drive new 

and unique solutions to tackle the 

challenges of high MOQs, long-leadtimes, 

long tail, low volume products 

and slow-moving inventory. 

Waldom works with over 30 suppliers 

and is one of the broadest stocking 

distributors for many of the leading 

Connector and Electromechanical 

Global Suppliers, such as TE, Molex, 

C&K, Omron, Honeywell, etc. 

energy and connectivity for the new 

digital era. The government spending 

and consumer buildup of capital is 

yet to be invested and will start to 

flow more significantly in the last 2 

quarters of 2021 and into the first 2 

quarters of 2022. Therefore, it is my 

belief that the electronic component 

will see a strong demand for at least 

another 18 months before significantly 

cooling off. 

Where do you see Challenges and 

Opportunities of 2021? 

Peter Rovekamp: As the world starts 

to emerge from the Covid-19 pandemic, 

the strain on global logistics and 

commodities has led to a surge in 

demand for electronic components. 

The three technological advances 

that are merging significantly are 

Electric Vehicles, IOT “Internet of 

Things” and 5G transition. These 

are driving increased demand for 

connectivity and power, which, in 

turn, is driving huge demand on 

all types of components. This “Big 

Bang” is putting tremendous pressure 

on component suppliers, as OEMs, 

CMs and end-users seek to drive 

increased production. This demand 

is being increased by government 

spending on infrastructure, green 

What do you think are the advantages 

of Bürklin Elektronik customers 

through the cooperation of Bürklin 

Elektronik with Waldom? 

Peter Rovekamp: Bürklin Elektronik 

customers will be needing a wider 

range and deeper quantity of electronic 

components across a broader line 

of Suppliers and will seek to have the 

local support to prevent being part of 

the logistic challenges. By choosing 

Bürklin Elektronik you will have a 

local partner that is eager to stock 

the products you need and together 

with Waldom relationship support 

over 250,000 unique products in 

stock and ready to deliver from stock. 

This will allow Bürklin Elektronik 

customers reliability that is required 

in this high demand market. 

The customers will also be able to 

drive local solutions with Bürklin 

Elektronik by sharing demands and 

packaging needs to support timely 

and accurate deliveries. 

How do you think Covid-19 will affect 

the electronics industry? 

Peter Rovekamp: We are all looking 

forward to putting Covid-19 behind 

us and moving back to a world where 

we can engage more socially and 

closer together. However, this may 

be a challenge for our society, as Covid-19 

may be replaced with another 

virus in the future. Therefore, the 

goal will be learning how to contain, 

understand and prevent the spread 

of viruses in the future. This will 

mean improvements in technology 

(sensors), protection (medical gear), 

communication (apps, tracking, etc), 

and transportation (mass transit). 

Many of the lessons learned will be 

key to prevent future epidemics from 

becoming pandemics. 

As you mentioned, Waldom is constantly 

investing in innovative new 

customer solutions – give us a look 

into the future? 

Peter Rovekamp: Stocking products, 

especially in a hot market, is difficult 

and can be risky. Waldom has the 

knowledge and experience to know 

what stock to invest in and shares 

this information with key partners to 

best support the market demands. 

Waldom helps to review with Distributors 

which stock should be bought 

and how much should be leveraged 

from Waldom. Waldom is committed 

to ensuring that our Distributor partners 

never stock more than they 

need. If they do face the challenge 

of excess as the markets ease and 

soften, we work with them to solve 

these challenges.
