Automotive & transport
Identical a thousand times. Reliable for years.
Connection, cable and harness solutions for vehicles, charging infrastructure, rail and test rigs — where vibration, temperature and volume come together.

Where connections move with the vehicle.
A connection that vibrates, runs hot and still has to be identical ten thousand times over.

Where Belko fits
Eight places where the connection decides.
From the charging connector to the harness behind the panel — each one is a starting point in the Belko range.
Application areas
Shock & vibration
A positive lock and support close to the connector, for the life of the vehicle.
Cable & jackets
A jacket chosen for temperature, oil, abrasion and flexing.
Sensors & on-board data
Sensors, cameras and on-board networks, with the right shield.
Harnesses at volume
Built to your drawing and tested — identical from prototype to series.
Sealed interfaces
Road, splash and outdoor conditions: sealed at the connector and the termination.
Power connections
Connectors for charging and power, chosen for current and mechanical load.
Temperature
Jacket and connector both cover the full temperature range.
Test rigs
Cable and connections that are plugged and unplugged every day.
Industry challenges
What mobility asks of a connection.
These rule out whole product families at once — so they come before the part number.
Vibration & shock
Vibration for the life of the vehicle calls for a positive lock and for cable support close to the connector.
Temperature range
Jacket and connector both have to cover the full range. The outer jacket is the part most often overlooked.
Reproducibility at volume
Connections that have to be identical thousands of times over — and keep doing the same thing for years.
Moisture, salt & dirt
Road, splash and outdoor conditions point to a sealed connection — at the connector and at the termination.
Electrical load
Current, voltage and insulation decide the cable and the contacts — alongside the mechanical requirements.
EMC & interference
Power electronics sit next to sensors and data. The shield and how it is terminated decide what reaches the signal.
Oils & fluids
Oils, fuels and cleaning agents narrow the choice of jacket and seal material to what withstands them.
Total cost of ownership
Better interconnect design lowers the cost over the life of the vehicle — not just the price of the part.

Technical expertise
Why automotive engineers choose Belko
- 01
A broad technical portfolio
Around 11,800 articles — connectors, cable, accessories, enclosures and tooling — including Telegärtner and FCT, a Molex company.
- 02
Selection from the requirement
Start from vibration, temperature and volume rather than the part number. A specialist compares the alternatives with you.
- 03
Access to specialist manufacturers
Belko sources components worldwide. If it isn’t in the catalogue, we go and find it.
- 04
Engineering in the design phase
Engineers think along early, identify bottlenecks and propose improvements — before the harness is fixed.
- 05
Harnesses built and tested in-house
Crimped, soldered, braided, overmoulded and electronically tested on Schleuniger, Komax and GWL equipment.
- 06
Supply for series production
Purchasing, sourcing and logistics handled from your enquiry on — with just-in-time stock control and vendor managed inventory.
Search & advice
Need a connection that holds up on the road?
Search the technical catalogue by part number, type or property — or tell a specialist about the vehicle, the environment and the volume.
Engineering questions
Frequently asked engineering questions
How do I find the right connector for my application?
Start from the environment rather than the part number. Temperature, vibration, sealing, electromagnetic interference and expected service life narrow the field faster than a catalogue search does, because they rule out whole families at once. Work through the three questions on this page to land in the right category, then have a specialist confirm the selection against your drawing or specification before you order.
Start with your applicationCan Belko supply custom cable assemblies?
Yes. Belko assembles single wire, multi-conductor cable, ribbon and coax — crimped by hand and by press, soldered, braided, twisted, overmoulded and electronically tested, from prototype through to series production. If you would rather start than call, the cable assembly configurator collects what you already know in seven short steps and a specialist completes the technical configuration from there.
Start your cable assemblyHow do I know whether I need a waterproof connector?
It depends on what the connection is exposed to rather than on where it sits. Outdoor installations, washdown areas, dust, condensation and splashing all point to a sealed connector, and an IP rating is the shorthand for how much of that a component keeps out. Sealing is decided at the termination as much as by the connector itself, which is why the assembly method matters as much as the rating.
What IP67 and IP68 mean for connectorsCan Belko help with shielding and EMC requirements?
Yes. Shielding is a design question Belko's engineers take part in: foil, braid and combined shields behave differently, and the right choice depends on the frequencies involved, the length of the run and how the shield is terminated. Electrical and mechanical requirements are part of design support, which is where the cable, the connector and the termination are chosen together rather than one at a time.
Foil, braid or both?Can Belko help find an alternative for an existing connector?
Yes. Comparing alternatives is part of product selection at Belko, and components that are not in the catalogue are sourced worldwide. Bring the part number you are replacing and, if you have it, the reason you are replacing it — an end-of-life notice, a delivery problem or a requirement that changed. The reason usually decides which properties of the original actually have to be matched.
