edra high-tech wires for automotive
Car PC
Semi-finished products for electronics
and electro technology
Under the corporate trademark bedra ® Berkenhoff
develops, produces and distributes high-tech wire
solutions for electronic and electrical applications.
Customized wires in various alloys of tin-bronze,
brass, nickel silver and copper.
Highly conductive, spinodal and special alloys are
added. Berkenhoff GmbH offers serrated wires in all
standard sizes and variants. Surface coatings of tin,
nickel, silver or gold round off the product line.
bedra electronic wires – present in all
growth markets
bedra ® electronic wires dominate in markets of the
future: aviation and aerospace, telecommunications,
automotive industry, information technology,
industrial technology and entertainment industry ...
You will find bedra ® electronic wires worldwide in
passive and electro-mechanical components.
Primary areas of application for passive components
are coil formers and capacitors. Electromechanical
components are used for relays and
connector pins.
A novelty in the bedra ® distribution programme are
ribbons and flexible flat cables (FFC).

„Tomorrow's Technology“ with
bedra electronic wires
Electronic assistance and infotainment in the automobile
of the future! – Steering systems without
steering column, brake systems without hydraulic
cables. On the display, usually showing speed and
fuel level, appear e-mail, navigation system or
appointment calendar. The mouse for this is rolling
in the steering wheel. – That’s drive-by-wire!
bedra ® is already supporting well-known drive-bywire
systems suppliers with the intelligent connecting
of vehicle functions. For example with flexible
flat cables in advanced window technology and
with solid contact connectors that are resistant to
environmental conditions.
bedra electronic alloys for telecommunications
With UMTS (Universal Mobile Telecommunications
System), the mobile telecommunication industry is
on the brink of its next performance explosion:
pictures, web sites, video conferences: Data transmission
with up to five megabit per second. That’s
how the world of mobile phones will look tomorrow!
Inside every mobile phone there are 300 to 400 passive
components – interwoven with current-carrying
bedra ® electronic wires. For example in OWF components
filtering out interferences in electrical
signals. Spring contacts of bronze, nickel silver or
special alloys are added. OK! - Talk to us about
electronic wires for your Plug&Play applications.

bedra alloys in electric
and electronic contact systems
Bits, Bytes and Terabytes are shooting through
speech and data strands – which have long been
linked into a global network. This means: billions
of pins of bedra ® electronic wire in board-to-board
connectors, micro-switches, modular connection
systems, relays, resistors and coaxial contacts for
high-speed and multimedia applications.
With bedra ® being your reliable and experienced
partner of developments for integral solutions in

Berkenhoff experience in non-ferrous wires and the
range of more than 100 various alloys for "quality
connections".
A multitude of materials for a multitude
of connections in industrial electronics
Whether racks or robotics! Medical technology or
industrial electronics: passive and electro-mechanical
components are always present. – Connector
pins are serving here as a connecting link between
electric and electronic components: from component
to printed circuit, from assembly to assembly
sub-rack, from device to device. Whether rectangular,
trapezoidal or round connectors, spring elements
or shielded connectors: – bedra ® offers the
multitude of alloys for miniaturised connections
with solid contact. Corrosion resistant, whisker-safe
– and perfectly conductive! In a word: a range of
materials to international standards.

bedra high qualities
for the consumer electronics
High-tech in the consumer electronics is seeking
contact to the "high quality wire". Alloy consistency
(due to the use of virgin metals of highest purity)
shape stability, precision in corner radius and exactly
reproducible quality are imperative even for the
smallest contact pin. In every length, for every profile,
with every surface, serrated or not, and on every
spool. Here again, bedra ® electronic alloys are faced
with high vibration stress and variations in temperature.
bedra ® high-tech wires are outstanding for
their strict adherence to specifications, and a costeffective
and automatic processing.

bedra know-how for speciality
applications in important future markets
Every second development of a bedra ® electronic
wire is the result of a solution to a customer specified
problem. Every customer specified problem our
R+D engineers are confronted with, leads to a keyaccount-task!
Resources and material properties,
process technologies and production logistics must
be adjusted to standards and customer requests –
and brought into an economic cost-benefit-ratio.
Today’s focus of interest are aviation and aerospace
applications (for example network systems for
aircrafts), the recent field of application, traffic
control engineering, and applications for which the
passing of salt spray tests against aggressive media
is of great importance.
