Cable & wire harness assembly, discrete to multi-branch.

Industrial and mil-spec cable, wire, and harness assembly to IPC/WHMA-A-620 Class 2 & 3 — from simple discrete wires to complex multi-branch, multi-connector builds.

Overview

Where failure isn't an option, we're already qualified.

SEI maintains an extensive crimp tooling library built over decades of harness work, so odds are good we already have the applicator your connector system needs. Crimped terminations are pull-tested to verify mechanical integrity, and we perform potting per your specification where the design calls for it. From point-to-point jumpers to harnesses spanning dozens of branches and connector types, every build is made to print with full traceability.
