Sealed wire harnesses for marine sensors, EV charging ports, outdoor IoT, and washdown equipment. Peripheral seals, cavity plugs, and overmolded strain relief — validation runs in-house, no third-party lab queue.
IEC 60529 IP ratings describe a 30-minute lab test. A waterproof harness that passes IP67 in the lab can still corrode in the field if the wire seal size is wrong, the cable jacket loses elasticity at −20 °C, or the connector backshell has a tooling-line micro-channel. We build against actual environmental envelopes: temperature swing, UV exposure, chemical contact, and flex count — not just the IP digit.
For builds where sealing is the dominant constraint, you are on the right page. If your harness is also high-voltage, see high-voltage harness — we stack the two specs. If sealing is delivered through TPE overmold rather than a connector seal, route via overmolded harness. For the unconstrained custom baseline, see custom wire harness.
