Cables, hubs, and custom cable assemblies.

A US-based cable assembly supplier for USB-C, HDMI, Ethernet, coax and fiber cables, USB-C hubs, and custom assemblies — molded, terminated, and 100% tested. Standard types or built to your drawing.

Why source connectivity from Kestner

A cable assembly manufacturer, not a reseller

We came up in cable and wire manufacturing. Custom cable assemblies are cut, stripped, terminated, overmolded, and 100% continuity-tested on a qualified partner line.

Overmolded and custom to your drawing

Bring a drawing or a sample. We build connector-to-connector assemblies, custom overmolds, and bulk cable — USB, DC, coax, fiber, and circular connectors.

Certified where it matters

USB-IF and e-marking on USB-C, UL AWM and CMR/CMP jacket ratings, TIA-568 for Ethernet, HDMI ATC, and RoHS — the marks your team audits against.

One accountable US contact

You buy from a US-based company and reach a person who prices and owns the outcome, in US business hours.

The marks every build carries.

Product certifications on the label, the packaging, and the documentation your procurement team audits against — verifiable by file number on request.

Connectivity — common questions

Can you make custom cable assemblies to our drawing?

Yes. We build custom cable assemblies to your drawing or sample — cut, strip, terminate, overmold, and 100% continuity-tested, with your part number and artwork on the carton.

Do you overmold custom connectors?

Yes. We produce overmolded cable assemblies with custom strain-relief boots and connector housings, from USB and DC barrel to circular (M12) and connector-to-connector builds.

Are your USB-C cables USB-IF certified and e-marked?

Yes. USB-C cables are built to USB-IF spec with e-marker chips on assemblies rated 100 W and above, and UL AWM 2725 jacket ratings.

Do you supply bulk cable?

Yes. Bulk Ethernet (Cat5e/6/6a), coax (RG6/RG59/RG11), and other cable on the spool or box, alongside finished assemblies.

What is the minimum order quantity and lead time?

Both depend on the assembly and how much is customized. Send your drawing and target volume and we will quote MOQ, lead time, and price together.

Can I choose whether my cable is made in Vietnam or China?

Yes. Our core cable lines run in both Vietnam and China on one drawing set, so you elect the country of origin — documented per unit — without requalifying the product. That makes China-plus-one and tariff planning a line on the purchase order, not a project.
