Industry 4.0:

smart, robust, connected-

From measurement technology

to energy supply –

these key technologies

make industrial processes

more efficient and

future-proof.


7

Production processes are becoming smarter, more networked and

more dynamic. Industry 4.0 represents a new level of industrial

efficiency – driven by smart data management. But what exactly

is needed to enable processes to react in real time, machines to

communicate independently and energy to be used efficiently? And

what technologies make the networked industry possible in the

first place? This much can be revealed: measurement technology,

data infrastructure and energy supply are among the key functions.

Bürklin provides information on how innovative components are

shaping and influencing Industry 4.0 in the long term.

Industry 4.0 is more than just a buzzword. It stands

for a profound change – away from isolated production

islands and towards networked, flexible and

self-optimising systems. Comprehensive automation

processes are at the heart of this development.

They ensure fast and precise industrial processes.

Automation is more than just a means of increasing

efficiency – it has become the standard and a driver

of innovation in industrial value creation.

The challenges involved are complex: shorter development

cycles, customised products, volatile

supply chains and increasing cost pressure call for

manufacturing environments that are both flexible

and highly reliable. This requires smart measurement

technology, fast data transmission, efficient

energy management, reliable switch cabinet technology

and protective components. Manufacturers

are faced with the task of consistently developing

their products further. Today, components for

demanding industrial environments must not only

be powerful, but also resource- and cost-efficient,

extremely safe and, above all, smart and ready for

the future.

Measurement technology:

the backbone of real-time processes

Precise data is required for well-founded decisions.

Without reliable measurement data, automation

cannot be implemented. In modern production

environments, measurement technology has long

been more than just a means of control – it forms

the basis for every data-driven decision. Sensors

and measurement systems continuously provide

precise information about processes, states and environmental

conditions. Only reliable measurement

technology can provide the transparency needed to

control, optimise and adapt processes in real time.

Depending on the field, there are specific requirements

for the measurement technology used,

which manufacturers must take into account at all

times. This is the case in the automotive and battery

industries, for example. In this rapidly developing

sector, increasingly precise, reliable and repeatable

measurements are required. Stäubli has responded

to the needs of the industry and now offers

Isoprobe measurement solutions that impress with

their excellent insulation, mechanical robustness

and the necessary signal quality. And that even in

demanding environments, such as those with high

frequencies.

Stäubli Isoprobe technology

Real-time data transmission

Real-time capability is a basic requirement for adaptive

processes, predictive maintenance and AI-based

controls. Single-pair Ethernet components are

playing an increasingly important role in industrial

networking. The smart design of the hardware

keeps the communication infrastructure as efficient

as possible. In addition, it is a cost-effective solution

for setting up Ethernet networks using existing

cables. This means thinner cables, smaller connectors

and combination with power-over-data lines.

Data is conveniently transmitted between two

points via a two-wire line, while a reliable power

supply is provided at the same time.

Würth Elektronik RD041

The result is clearly structured networks in which

data and energy flow efficiently, securely and synchronously

– without complex cabling concepts.

Using energy intelligently

Reliable measurement technology is also extremely

important in the field of energy management. The

reason is obvious: digitalisation, energy prices and

legal requirements are putting increasing pressure

on companies and manufacturers. In the future,

resources will have to be used even more intelligently

and sustainably. Intelligent energy measurement

technology is the key to this mammoth task. The

goal: to monitor energy parameters reliably. Janitza

offers a practical and, above all, future-proof solution

in this area with the UMG 604-PRO network

analyser. The model records basic power quality

parameters and helps to detect network faults at

an early stage and respond to them promptly –

saving time and money and thus forming an integral

part of a sustainable predictive maintenance strategy.

An Ethernet connection and the easily integrated

UMG 96-EL make commissioning extremely

simple.

Janitza UMG 604-PRO

Switch cabinet solutions for Industry 4.0

Demands are growing, especially in industrial

control cabinet construction: components must be

compact, integrable and resilient. At the same time,

reliable network cabling is required. Pre-assembled,

robust patch cords designed for areas with high

terminal density simplify installation. They are less

prone to errors and guarantee secure data connections

thanks to flexible cable solutions – even in

confined spaces.

Tip for industrial control cabinets:

Organisation is key. This is especially true

for Industry 4.0. Whether blank labels for

manual labelling or efficient thermal transfer

printing – robust and clear signage provides

optimal orientation. And orientation, in

turn, promises maximum efficiency.

The future of industrial labelling:

RFID transponders with integrated sensors

for contactless real-time transmission of

temperature, pressure and humidity

Various protective components play a central role

here. Manufacturers such as ESKA develop products

that are specially designed for use in industrial automation

and communication systems. The spectrum

ranges from fine fuses in glass or ceramic designs

to SMD models for compact assemblies and fuse

holders for PCB and device mounting.

ESKA fuses for the future of Industry 4.0

Development trends:

miniaturisation & AI evaluation

Industrial manufacturing as a whole is at a turning

point: Industry 4.0 has long been a reality – but

its full potential can only be realised through the

interaction of highly specialised technologies. Measurement

technology, data transmission, energy

management, control cabinet technology, protective

components and intelligent operating solutions are

no longer individual disciplines, but system-relevant

building blocks of a continuously networked

infrastructure. Future-proof automation therefore

means intelligent components with open interface

technology, high diagnostic capability and standard-compliant

safety. And development continues:

innovations in the field of AI will once again shake

up Industry 4.0.

In any case, looking ahead, it is clear that those

who set up their infrastructure smartly today – modular,

networked, robust – are laying the foundation

for long-term competitiveness in the networked

industry of tomorrow.

HellermannTyton Thermal transfer printer

Protective components: safety first

A stable, secure infrastructure does not begin with

the control unit – it is created through reliable protection

at every level of the system. In this context,

high-quality safety devices make an often invisible

and underestimated but essential contribution to

the reliability of complex systems.

Reliable protection solutions are indispensable,

especially in the field of sensitive measurement

technology, intelligent power supply and data-based

control systems. This is because overcurrent,

voltage peaks or short circuits can not only damage

components, but also interrupt entire processes –

with corresponding consequences.

The future of control elements

Not to be forgotten: Industry 4.0 is not only changing

processes, but also the way humans and machines

interact with each other. In highly automated

environments, control units must do more than

just start and stop functions. Compact, robust and

intuitive systems are required that can be flexibly

integrated into modular production structures –

both physically and communicatively.

With solutions such as the E-BOX XL, RAFI offers

operating concepts that are specially designed for

use in networked production environments and

can be seamlessly integrated into automation

processes. The E-BOX XL IO-Link also meets the

highest demands in terms of connectivity and data

availability – including parameterisation and diagnostic

options. Additional sensors and actuators can

also be connected to the optional M12 GPIO

connection.

Interview

Stability in

volatile times is

our responsibility

Margit Kuther from the trade magazine Elektronik Praxis

interviews Holger Ruban, CEO of Bürklin Elektronik, about

geopolitical challenges, opportunities in cooperation with

China and strategies to combat component shortages.

Elektronik Praxis: Mr Ruban, how is the ongoing

tariff dispute between the US and other economic

areas affecting your company?

Holger Ruban: Although we, as a European distributor,

are not directly affected by the US tariffs, we

are nevertheless clearly feeling the effects of such

geopolitical tensions – primarily due to our international

manufacturing relationships. Delivery times

are getting longer, procurement costs are rising and

the supply chain is becoming more complex. That

is why we focus on reliable stock availability and

transparent processes for our customers, so that we

remain a trustworthy partner even in challenging

times.

Elektronik Praxis: China is currently seeking

closer ties with Europe. How do you assess this

development from the perspective of electronics

distribution?

Holger Ruban: This development undoubtedly

brings opportunities – for example, in terms of

access to modern manufacturing capacities or

the expansion of our product portfolio.

However, stronger economic ties also bring dependencies

and political risks that we must not ignore.

Our goal is to maintain a balanced approach: we

rely on a broad supplier base, strong partnerships in

Europe and conscious risk diversification. This allows

us to remain flexible and independent – to the benefit

of our customers.

Elektronik Praxis: Global supply chains are

considered unstable. Do your customers need

to prepare for another component shortage?

Holger Ruban: Although the situation has eased

compared to the height of the chip crisis, selective

bottlenecks remain an issue – especially for complex

semiconductors and passive components. We are

meeting this challenge with strategic warehousing,

close coordination with our manufacturers and

data-driven forecasts. Our customers benefit from a

warehouse with over 500,000 items and our ability

to respond to changes at an early stage. Reliability

in volatile times – that is our claim.


13

Elektronik Praxis: Mr Ruban, how do you assess

the current market situation in Germany – particularly

with regard to the automotive industry?

Holger Ruban: The automotive industry is undergoing

fundamental change – technologically, economically

and structurally. At the same time, economic

uncertainty is leading to weaker demand.

We are also feeling the effects of this development

in distribution: investments are being postponed

and orders are being placed at shorter notice.

But it is precisely these challenges that create new

opportunities – for example in the field of electromobility,

charging infrastructure or sensor solutions

for autonomous driving. As a distributor, we see

it as our task to actively shape this change – with

technical expertise, a broad product range and the

necessary flexibility.

Elektronik Praxis: The debt brake is being relaxed

for defence spending. Will this also increase demand

in the security and defence sector for you?

Holger Ruban: We are definitely seeing increasing

demand in these segments. Components with special

requirements or military approvals are more in

demand than ever.

Many of our customers are preparing specifically

for these markets or are already active there. As a

reliable partner, we support them with our many

years of experience and direct access to certified

manufacturers.

Elektronik Praxis: Are you observing a strategic

realignment among suppliers – for example,

towards the defence or aviation industries?

Holger Ruban: Yes, and increasingly so. Many companies

that used to focus heavily on the automotive

industry are now specifically evaluating new markets

– from defence and aviation to medical technology.

The requirements are high, especially in terms of

compliance with standards and quality standards,

but the change is noticeable. We see it as our task

to support this transformation process with reliable

distribution, technical advice and a product range

tailored to these industries.

”Suppliers are looking for new

ways and we accompany them“


15

”Resilience and customer proximity

are the success factors today“

Elektronik Praxis: Mr Ruban, how does a distributor

like Bürklin Elektronik need to position itself

in order to remain successful in these economically

and geopolitically challenging times?

Holger Ruban: Today more than ever, a stable

foundation, flexibility and innovative strength are

needed. We rely on a broad, well-stocked product

range, fast delivery and digital services that offer

our customers real added value. At the same time,

we remain close to the markets and the needs of

developers, purchasers and project managers. Our

role goes far beyond that of a traditional distributor

– we see ourselves as a strategic partner to our

customers.

Elektronik Praxis: Bürklin has launched by.B,

a new own brand for business customers.

Are there plans to expand the range to include

the defence industry?

Holger Ruban: by.B is a strategic step towards serving

our business customers even more effectively –

with selected products, high availability and direct

ordering. In the defence sector, we are definitely

seeing increasing demands in terms of quality,

robustness and specification compliance. We are

currently analysing intensively how we can further

expand our product range in this segment. In doing

so, we strictly adhere to regulatory requirements

and work closely with certified manufacturers. Our

focus is on being a reliable partner wherever precision

and safety are required.

>>

”The electronics sector

remains a growth area -

also in Germany“

Elektronik Praxis: Mr Ruban, in conclusion, how

do you see the future of the electronics industry

and Germany as a business location?

Holger Ruban: The electronics industry plays a

central role in almost all areas of the future – from

the mobility transition to digitalisation and energy

supply. Accordingly, we see stable, if not increasing,

demand in the long term.

As far as Germany as a location is concerned, the

foundations are there – strong industry, excellent

research, committed small and medium-sized enterprises.

Now it is important to promote innovation,

reduce bureaucracy and invest in education and

infrastructure. If we succeed in doing so, Germany

will remain a strong location for innovation – and

a relevant driver for the electronics industry in

Europe.

The interview was conducted by Margit Kuther

from the trade magazine Elektronik Praxis.

with the functionality of the control panel.

Salt and corrosion: Salt water and dust

cause rust, damage and corroded

markings, which shortens service life.

UV radiation: Continued UV radiation

causes colours to fade, deteriorates

materials and weakens seals.

Frequent washing: High-pressure

cleaning can damage components and

seals without appropriate protection.

APEM protection solutions:

APEM‘s customised HMI solutions

are designed for use in harsh

conditions:

Protective seals and coatings: ensure

IP protection (up to IP69K) against

dust, water and chemicals.

Points to consider when

selecting the best enclosure

for a new project

The project design has been finalised. The functionality

and features have been signed off and the PCB

layout has been committed. Despite the entreaties

of enclosure manufacturers to specify the enclosure

early in the design cycle, in the real world the enclosure

is quite often one of the last components to be

considered, despite the disproportionate impact and

cost that a poor selection can have.

The enclosure ensures mechanical protection for

the housed electronics and it protects against the

ingress of dust, water and other substances. The

material from which it is manufactured will be suitable

for the environments in which the product will

be installed. It provides security against unauthorised

access and it provides suitable surfaces for the

installation of external components.

The key criteria.

Size

It is often easier to reconfigure the PCB during the

development process than to have to specify an

unnecessarily large enclosure. How large and what

shape are the PCB and other components? How

much space is needed on external surfaces for any

indicators, switches, connectors, cable entries and

similar components? What space is required for

board-mounted components, stand-alone electromechanical

components or multiple horizontal

boards?

Installed environment

For outside installation, UV stability is an issue for

plastic enclosures. For road and rail applications,

shock and vibration must be considered. Will the

ingress of dust and water be a possible problem?

Are there likely to be oil and chemicals present? Is

impact resistance a problem? Are particularly high

or low temperature expected?

Enclosure materia

The main choice is between ABS and polycarbonate

plastic, aluminium, stainless steel and GRP.

Polycarbonate and GRP are better for outdoor use

because of their resistance to UV embrittlement and

colour fading.

Die-cast and extruded aluminium enclosures are

robust, non-corrosive, lightweight, non-magnetic,

easily machined, gives good impact resistance and

are electrically conductive. For applications where

protection against shock damage is important,

where EMC is likely to be an issue or where high

temperatures, dust or water are expected to be present,

an aluminium enclosure is often the preferred

choice.

Stainless steel is particularly suited for use in pharmaceutical

and food processing plants, where its

cleanability, strength, and corrosion resistance are

beneficial. It also has high impact resistance.

GRP is light weight, stronger than many metals,

non-magnetic, non-conductive and it is chemically

inert.

Environmental sealing

The relevant standard is IEC 60529. Over-specification

can easily lead to excessive cost. Is the product

likely to be immersed in one metre of water (IP68),

or is it going to be used in a benign office environment

(IP54), in an aggressive environment (IP65) or

will it be installed in a food or pharmaceutic manufacturing

environment, where frequent cleaning

with high temperature, high pressure water jets is

required (IP69)?

EMC

Aluminium enclosures will provide a degree of EMC

likely to be more than sufficient for most commercial

applications. Plastic enclosures are non-conductive

so they provide no EMC attenuation, but they can

be given an internal conductive coating to create a

conductive surface.

Modifying standard products

to suit the project

While standard products have many benefits such

as field-proven designs, good availability and no

up-front NRE costs, they will inevitably need to be

modified for use in the project. The design engineer

has three choices.

1. Purchase standard products

If there is in-house capability, to modify the enclosure

as a part of the overall manufacturing process

could be the best way to proceed. However, more

standard units than are wanted will have to be

bought to allow for set-up procedures, prototypes

and wastage.

2. Outsource the modifications

to external suppliers

There are the additional costs, time penalties and

logistical complications associated with managing

the process of sub-contracting, often to multiple

suppliers.

Use the enclosure manufacturer

By far the best option is for the original manufacturer

to provide a modified version of a standard

enclosure configured to the specific requirements

of the project.

Hammond’s in-house capability includes

- Holes

- Cutouts

- Tapping and countersinking

- Pressed-in hardware such as studs

and standoffs

- UV digital printing

- Silk screening

- Special colours

- Special length extrusions

- Pre-installed accessories

Labelling in

Industry 4.0 -

orientation creates

efficiency

In a digitalised industry, data, networking and efficiency count more

than ever. But it all starts with something seemingly simple: clear,

reliable labelling. After all, no digital structure can function without

clear physical order. Whether in the control cabinet, on machines or in

logistics, professional marking is the backbone of Industry 4.0.

Fast and flexible:

manual marking on site

When things have to be done on the spur of the

moment or no printer is available, manual marking

offers a smart alternative. Pre-printed or blank labels

can be marked directly with a permanent ink pen

and adhere securely to cables, equipment or components.

Ideal for service teams and small volumes,

HellermannTyton provides high-quality materials for

every application – from self-laminating labels for

harsh environments, to pre-punched panel plates

for use in equipment manufacturing.

High-quality and efficient:

thermal transfer printing at

the point of use

For high-volume or complex marking tasks, thermal

transfer printers combined with TagPrint Pro software

offer a powerful system which enables data

import, standards-compliant layouts and seamless

process integration – all on site. Whether heat shrink

sleeves, labels or cable markers, the print quality

is durable, precise and even suitable for extreme

industrial conditions.

The solution for every industry

IEach industry has its own marking needs and

HellermannTyton has the right solution for each

one. From automation to energy, rail to medical

technology, our portfolio includes printable heat

shrink sleeves, durable polyester or vinyl labels

and laser-engraved signs that withstand heat,

cold, chemicals and UV exposure – for maximum

clarity and lasting identification.


31

Robust marking for

long-lasting information

Plastic or metal plates are the preferred choice

where information must remain visible over time –

like type designations or inspection markings. They

can be securely attached with cable ties and printed

in-house, improving efficiency in both mechanical

and electrical engineering.

Orderliness in the switch cabinet

Clear labelling in the control cabinet saves time,

reduces errors and boosts safety. The Helatag series

from HellermannTyton delivers a coordinated solution

with matched carriers and markers for terminals,

devices and cables. Paired with thermal transfer

printers, even complex series labelling can be implemented

quickly and in compliance with standards.

Making safety visible

Markings that warn, inform or guide help ensure

operational safety. HellermannTyton offers a broad

range of standard-compliant warning and inspection

labels – ready to personalise for use on machinery,

during maintenance or for statutory inspections

such as DGUV testing.

RFID technology:

digital transparency meets

robust practice

RFID transponders with integrated sensors bring a

digital edge to industrial identification. These tiny

chips provide unique object IDs and record data like

temperature, pressure or humidity – wirelessly and

in real time.

Designed to perform in demanding conditions –

from moving equipment and hard-to-reach areas

to autoclaves – RFID helps cut wear, reduce maintenance

and support reliability. Passive variants

operate without a power source, while semi-passive

versions offer extended data storage and battery

options for long-term monitoring in logistics, production

or building services.

Backed by decades of plastics expertise, Hellermann-

Tyton RFID solutions are easy to integrate with cable

ties, screws or rivets. Our advantage: the fusion of

robust construction, smart features and practical

installation – unlocking new potential for quality

assurance, maintenance and automation.

New everyday hero:

QPD STAK/ STAS installation

connectors for

sun protection systems

Connecting sun protection systems is no challenge

with the right installation connector. The QPD STAK/

STAS 3 with IDC cutting connection eliminates the

hassle of loosening and tightening screws. Tedious

assembly is a thing of the past with this innovative

connection technology.

The mains connection of external blinds, venetian

blinds, roller shutters and awnings is usually made

via a four-core connection cable, which is connected

to the motor using the STAK 3 connector (field side,

socket) and the STAS 3 mating connector (device

side, pin). Installing these connectors used to be a

complex and time-consuming task, as a large number

of screws had to be tightened to connect the

conductors and provide strain relief for the cable.

With the QPD STAK/STAS 3 installation connectors

from Phoenix Contact, this connection can be made

in no time at all, even in hard-to-reach installation

situations and under harsh weather conditions. No

special tools or screwdrivers are required thanks to

Quickon quick connection technology.

The connection technology offers secure installation

in just a few steps: After stripping the cable, it is

simply fed through the union nut into the connector

housing of the QPD STAK/STAS 3 and the individual

conductors are fixed in the clamping body. The union

nut is then tightened. The connector‘s insulation

displacement terminal cuts through the conductor

insulation, establishing a reliable, gas-tight electrical

contact. The strain relief is automatically provided by

the seal; no additional work is required (see QR code

for installation video). Both rigid and flexible cables

with a cross-section of up to 1.5 mm² can be connected.

Since there is no need to strip and attach

a splice protector to the conductors or to laboriously

loosen and tighten screws, connection time

is reduced by up to 80% compared to conventional

connection techniques. This significantly reduces

not only the installation time on the building but

also labour costs.

The splash-proof and dust-proof housings (IP54)

also ensure a high level of protection outdoors and

guarantee a reliable and long-lasting electrical installation.

Even extreme temperatures (-40 °C to 100

°C) cannot affect the power distribution. The QPD

STAS 3 comes with a high-quality, corrosion-resistant

stainless steel bracket pre-mounted to ensure a

secure connection of the coupling. The QPD STAK/

STAS 3 connectors are plug-compatible with classic

motor connections for external blinds, Venetian

blinds, roller shutters and awnings.

The strategic role of oscilloscopes in

the automotive and battery industries

with high-precision

measurement technology

from Stäubli Isoprobe

In the rapidly evolving automotive and battery

industries, the demand for precise, safe and repeatable

measurements is constantly increasing.

Oscilloscopes – essential tools for analysing

electrical signals – play a central role in development,

validation and fault diagnosis throughout the

entire product life cycle. Whether analysing high-voltage

drive systems in electric vehicles or verifying

battery management systems (BMS),

reliable conclusions about signal integrity,

functional safety and system stability would be

impossible without modern oscilloscope

technology.

Precise measurement technology does not begin

in the device, but at the point of signal acquisition

– specifically at the probe. This is where Stäubli

Isoprobe measurement solutions come into play:

thanks to their excellent insulation and mechanical

robustness, they deliver the necessary signal

quality even in the most demanding environments

with high voltages and frequencies.

Oscilloscopes in automotive applications

In the automotive industry, various functional tests

are carried out for validation purposes. Some of these

involve high voltages in the kilowatt range and

can be performed with Stäubli Isoprobe probes.

Modern vehicles – especially battery-electric and

hybrid drives – have complex electronic architectures

with numerous control units (ECUs), highvoltage

components, sensors and communication

buses such as CAN, LIN or automotive Ethernet.

Oscilloscopes with mixed-signal functionality (MSO)

enable the parallel acquisition of analogue and

digital signals, which is indispensable for debugging

and timing analyses.

Another key area is the validation of driver assistance

systems (ADAS), especially radar and lidarbased

modules. This requires high-frequency signal

processing in the GHz range, where oscilloscopes

with high bandwidth and trigger capability as well

as suitable RF probes are crucial. Stäubli Isoprobe

probes with high-voltage capability enable precise

measurement in electromagnetically demanding

environments and contribute to compliance with

EMC limits.

In power electronics – e.g. in the analysis of inverter

and motor controls – transient-capable probes

are indispensable. Oscilloscopes with sample rate

timing (e.g. >1 GS/s) in combination with Stäubli

Isoprobe probes enable precise analysis of switch

edges or overvoltages.

Oscilloscopes in battery development

and testing

In battery development, the focus is on validating

cell chemistry, BMS functionality and thermal behaviour

under load. Oscilloscopes are used here to:

- Accurately measure cell voltages in the mV range

- Analyse cell balancing circuits

- Resolve charge/discharge cycles in time

- Detect fault conditions such as overvoltage,

ground bounce or EMC interference.

Stäubli Isoprobe probes offer a reliable basis for

precise measurements thanks to their high voltage

resistance and high signal purity – even with fast

bus interfaces such as SPI, UART or I²C.

In accordance with IEC standards (e.g. IEC/EN

61010-031:2015), passive oscilloscope probes from

the Isoprobe series can measure voltages to earth

up to max. 10,000 V, CAT II (Isoprobe II) or 1,000 V,

CAT III/600V, CAT IV (Isoprobe III) and comply with

strict regulations regarding air and creepage

distances – essential for product safety. In combination

with Stäubli Isoprobe probes, high-voltage

events up to the kV range can also be safely detected

without risk to measurement equipment or

personnel.

Bürklin order-no. 20K9205 20K9223

Conclusion

The electrification of the powertrain, increasing

electronics density and complex safety requirements

make high-performance oscilloscopes and highquality

probes indispensable tools in the automotive

and battery environment.

Stäubli‘s Isoprobe technology significantly expands

the performance capabilities of modern oscilloscopes:

their robust mechanical design and reliable

electrical isolation create the conditions for reproducible

and standard-compliant measurements –

even in harsh environments.

Engineers not only get precise measurement results,

but also a high level of safety and efficiency in

everyday testing. In a market where innovation and

regulation go hand in hand, this is a strategic advantage

– for tomorrow‘s quality, measurable today.

Ethernet communication

How to implement

single-pair Ethernet

with power-over-data

lines

Single-pair Ethernet is becoming increasingly popular in

industrial networking due to the simplified cabling with just

one twisted pair of wires. When power is added to this, the SPE

transmission standard with Power-over-Data-Lines is unbeatably

simple. The following reference design shows how to implement

SPE with PoDL.

The reference design for Single-Pair Ethernet (SPE)

with Power-over-Data-Lines (PoDL) from Würth

Elektronik (WE) is a system that can transmit data

between two points via a two-wire cable. The central

device supplies the peripheral device with power via

the same two wires over which the data is simultaneously

transmitted.

In the literature, Single-Pair with PoE is often also

referred to as SPoE, which is used in the following

explanations.

SPoE basics

SPoE differs from PoE in its definition and implementation.

It includes:

- a unique power coupling technique used

in a 2-wire circuit.

- simultaneous transmission of power and

data via a symmetrical, twisted pair of wires.

The data connections are realized via a single pair

of wires, AC-coupled at each end to avoid ground

loops. The PoE system transmits power simultaneously

with the data. Figure 1 shows the basic

circuit of the SPoE system. On the left-hand side of

the circuit diagram is the Power Source Equipment

(PSE) with the PHY (physical layer in the OSI model).

On the right-hand side is the Powered Device (PD,

load) and another PHY. The PHYs establish the data

connection and the PSE supplies the PD with power.

The data connection is capacitively decoupled (C1 -

C4) from the power and the power supply is inductively

decoupled (L1 - L4) from the data. The interface

is referred to as a „Media Dependent Interface“ or

„Port Interface“ (MDI/PI).

The integration of power supply alongside data

transmission requires a robust, classification-based

power supply protocol to ensure compatibility between

power sourcing equipment (PSE) and powered

devices (PD). The protocol is defined in IEEE 802.3cg

(SPoE, 2019) and explained in detail in [1].

Figure 1: Basic circuit of an SPoE system.


49

Figure 3: Top side of the PSE board, the SPE interface is located on the left,

the connection can be made either via a 3-pin plug-in terminal or an SPE connector.

The electrical requirements for SPoE are defined in

the following IEEE standards:

- IEEE 802.3cg (10BASE-T1):

Bandwidth 0.1 to 20 MHz, range up to 1000 m.

- IEEE 802.3bw (100BASE-T1):

Bandwidth 0.3 to 66 MHz, range up to 40 m.

- IEEE 802.3bp, (1000BASE-T1):

Bandwidth 1 to 600 MHz, range up to 40 m.

The cables used for SPoE differ from the standard

cables used for Ethernet [2].

SPoE requires cables that are defined in IEC 61156,

i.e. „multicore and balanced pair/quad cables for

digital communication“. Standard CAT 6 or CAT 7

cables, even if they are shielded, are not suitable.

SPoE can be integrated into a mixed system with

common industrial Ethernet protocols such as

Ethernet/IP, Profinet and EtherCAT and can provide a

simultaneous power supply for end devices. Figure 2

shows a typical setup.

SPoE hardware topology

The hardware topology of the SPoE reference design

RD041 consists of two boards, the PSE circuit and

the PD circuit. The interfaces with primary transient

protection, common mode chokes, transformers

and secondary transient protection to the PHY are

the same for the PSE and the PD.

Power and data are coupled together at the interface

via a power coupling network.

The SPE transmission path operates at a data rate of

10 Mbit/s with an amplitude of approx. 2.5 VPP, the

operating voltage on the two-wire line is 20 to 24

VDC.

The PSE and PD implementation are described in

detail in the paper of the reference design RD041

[1].

Figure 3 shows the top side of the WE PSE board,

Figure 4 the top side of the WE-PD board.

Further information on the implementation of the

PSE and PD boards with detailed circuit information

can be found at [1].
