Connections that keep machines running.

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.

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.

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.

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.

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.

A description of the application is enough to start — you do not need a part number. What speeds it up is the environment the connection sits in, what it has to connect, the quantity you need now and the quantity you might need later, and a drawing, datasheet or photograph if you have one. An attachment usually saves a round trip. Your question reaches a technical specialist, not a form inbox.
