Custom Cable Assemblies & Wire Harnesses

You’ve reached the home of the world’s #1 supplier of custom cable assemblies for aftermarket OBD-II and Jbus devices.

Atek, located in Orange County, California, has been supplying custom cable assemblies & wire harnesses to customers worldwide since 1996. We provide our customers with the dual benefits of offshore pricing and onshore service, including refreshingly responsive communication, first-rate business integrity, and the high level of technical expertise that can only be developed from years of experience.

Our production facilities are ISO certified and our cables are RoHS-compliant and guaranteed to match your approved specifications and samples. We do not compromise on quality – everything we quote and manufacture is made using top quality components, including connector housings, terminals, wire, fuses, tubes, braided sleeving, and other accessories. Whenever possible, we use UL listed parts and materials. We do not take cost-saving shortcuts that sacrifice the quality of your cable assemblies.

We can make cable assemblies and wire harnesses with multi-conductor jacketed cable, flat cable (including but not limited to ribbon cable), and discrete / hook-up wire. For applications in extreme temperature environments we can offer wire with expanded temperature range ratings.

The assembly and manufacturing processes we offer include cutting, stripping, tinning, crimping (including IPC/WHMA-A-620 Rev. A compliance), soldering, terminating, splicing, twisting, sleeving, tubing, heat shrinking, taping, and molding.

We focus in particular on automotive aftermarket cable assemblies, including vehicle telematics and diagnostics, but we make many other kinds of cable assemblies as well, including for sensors and instruments, displays, point-of-sale (POS) scanners and terminals, kiosks, and many other kinds of devices and equipment.

Whatever your application is, send us an email or give us a call to discuss your particular requirements. We can work from your descriptions, sketches, drawings, and/or samples.

Working with our proactive sales engineers will make your life easier, keep your projects on schedule, and result in delivery of both good cable assemblies AND a good experience!
