Main wiring harness for harvester display control

We use five primary sealing approaches depending on application requirements: O-ring sealed connectors from TE Deutsch, Amphenol, or Molex; custom overmolded terminations in PUR/TPE/silicone; epoxy or polyurethane potting for permanent installations; adhesive-lined dual-wall heat shrink for transitions and repairs; and custom silicone sealing boots for extreme temperature ranges. Most IP68 assemblies combine two or more methods to achieve redundant sealing.

Yes. We regularly overmold or pot standard connectors to achieve IP67 or IP68 protection when sealed variants are unavailable or too expensive. This requires custom tooling (typically $800-2,500 one-time cost) but eliminates the need to redesign your mating interface. We verify seal integrity with immersion testing per IEC 60529.

Every waterproof harness is tested per IEC 60529 for its specified IP rating. IP67 assemblies undergo 1m immersion for 30 minutes, IP68 assemblies are tested at 3m depth for up to 72 hours, and IP69K assemblies face 80°C water at 100 bar per DIN 40050 Part 9. We also perform 100% electrical continuity and insulation resistance testing (minimum 100MΩ at 500V DC) before and after IP testing to confirm no degradation.

rototype lead time is typically 10-15 working days for assemblies using off-the-shelf sealed connectors, or 3-4 weeks if custom overmold tooling is required. Production lead time is 2-4 weeks depending on volume and connector procurement. Unit cost varies widely by sealing method: O-ring sealed connectors add $2-15 per connection point, overmolding adds $3-8 per termination, and potting adds $5-20 per assembly depending on volume.

For outdoor UV exposure, we recommend PUR (polyurethane) or UV-stabilised TPE jackets, which resist degradation for 3,000+ hours under accelerated UV testing. For continuous submersion, silicone and cross-linked polyethylene (XLPE) offer the best long-term water resistance. Marine applications often require tinned copper conductors and LSZH (Low Smoke Zero Halogen) jackets to meet maritime safety standards. We select materials based on your specific chemical, thermal, and mechanical requirements.
