Contact Metallurgy & Plating Guide
- Gold Plating (Au): Unmatched resistance to atmospheric oxidation, fretting corrosion, and micro-motion degradation. Imperative for millivolt sensor circuits (knock sensors, Hall-effect crank triggers, wideband lambda) and differential CAN-Bus / LIN communications.
- Nickel Plating (Ni): High mechanical durability and excellent resistance to contact wear during frequent mating cycles. Standard for chassis switching, solenoids, and automotive accessories.
- Tin Plating (Sn): Suitable for cost-sensitive, steady-state DC power delivery (coils, electric fans, lighting), provided high contact normal force is maintained to avoid fretting.
- Solid (Machined) vs. Stamped & Formed (S&F):
- Solid Machined Terminals: Preferred in motorsport and aerospace for exceptional tensile pull strength under heavy vibration. Crimped using 4-indent / 8-indent hand crimp tools (e.g. HDT-48-00).
- Stamped & Formed Terminals: Ideal for production harness assembly and automated reel feeding using standard B-crimp tooling.
Cavity Wire Seals & Insulation Matching
Waterproofing depends on maintaining a uniform seal around the wire insulation:
| Seal Part Number | Wire Insulation OD Range | Material Composition | Ingress Protection Rating |
|---|---|---|---|
828904-1 | 1.2mm - 2.1mm | High-Grade Silicone / Fluorosilicone | IP67 / IP68 Submersion |
828905-1 | 2.2mm - 3.0mm | High-Grade Silicone / Fluorosilicone | IP67 / IP68 Submersion |
Engineering Tip: When using thin-wall high-performance motorsport wire such as Raychem Spec 55 (MIL-W-22759/32) or TXL, verify that the wire outer diameter falls strictly within the seal's minimum specification to avoid capillary water ingress.
Cavity Sealing Plugs (Blind Plugs)
Any unpopulated terminal cavities must be sealed to maintain submersible IP67/IP68 environmental protection:
| Cavity Plug Part Number | Function | Material | Installation Tip |
|---|---|---|---|
828922-1 | Unpopulated Cavity Seal | Thermoplastic / Silicone | Insert with tapered end forward until flush |
- Always install sealing plugs with the flared flange oriented outward towards the wire entry face.
- Push the plug until it rests flush against the rear grommet shoulder.

Harness Assembly & Crimping Best Practices
- Wire Stripping: Strip wire insulation cleanly (recommended 5.0mm – 6.5mm) without nicking or severing individual copper strands.
- Crimp Height Verification: Verify crimp height and terminal pull-out force using a certified calibrated crimper and micrometer.
- Terminal Insertion: Push contacts through the rear elastomeric grommet until an audible tactile click indicates positive retention.
- Secondary Lock Installation: Slide the wedgelock into the front face until it locks flush with the connector housing.
- Service & De-pinning: If de-pinning is required, remove the wedgelock with a hooked removal tool, then gently release the internal plastic retaining finger with a small flat blade screwdriver while pulling the wire from the rear.
