What we help with — Cable and Wire Harness Assembly

Cable and Wire Harness Assembly sourcing for St. Louis programs

Custom cable assemblies, wire harnesses, and overmolded connectors built to IPC/WHMA-A-620.

Our harness bench builds discrete wire harnesses, ribbon assemblies, coax and RF jumpers, fiber assemblies, power cables, and overmolded custom connectors. Termination capabilities cover crimp (hand and automated), solder cup, IDC, IDT, and ultrasonic. Common connector families include Molex, JST, Hirose, TE/Deutsch, Amphenol, LEMO, Glenair, and MIL-DTL-38999/26482 circulars for defense and aerospace. Build to IPC/WHMA-A-620 Class 2 or Class 3 with full continuity, hipot, and DWV testing. Volumes range from one-off prototype cables to production runs in the tens of thousands, with kitting and packaging support for downstream box-build. Conformal sleeving, braided shielding, expandable mesh, heat-shrink boots, and custom labeling are routinely included. We match each project to a shop with the right connector experience and certification scope — the right harness house for a medical device is rarely the right one for a UAV ground station.

Why SmartFab

Why St. Louis teams source cable & wire harness through SmartFab

One RFQ, one accountable partner

One cable & wire harness RFQ from St. Louis returns one accountable manufacturing quote — sized for your volume, your certifications, and your lead time.

Supply chain headache, eliminated

We own sourcing, production, and follow-up on every St. Louis cable & wire harness program so your team ships product instead of chasing shops.

Better supplier fit

Harness work is connector-family and certification driven — defense circulars, medical USP Class VI, and consumer overmolds each route to different shops. For St. Louis programs in aerospace & defense, that means placing the build on a line with the right certifications and volume profile from day one.

Build approach

Build approach for St. Louis cable & wire harness programs

When we route a cable & wire harness RFQ for a St. Louis customer, we evaluate the build against facilities in our network on three axes: certifications (does it need IPC/WHMA-A-620 Class 3 or AS9100?), volume (prototype, low-volume, production), and lead time. St. Louis's Boeing Defense presence and the broader agtech corridor need AS9100, ITAR, and ruggedized harness partners — our Midwest bench is structured for that mix.

For aerospace & defense programs in St. Louis, we typically return one accountable manufacturing quote within 24–48 hours.
