Key Connector Engineering Considerations​

When specifying connectors for severe vibration, high temperature, or submersible environments:

  • Contact Metallurgy: Choose Gold (Au) plating for millivolt sensor circuits and high-speed CAN networks to eliminate fretting corrosion; use Nickel or Tin for power switching.
  • Secondary Locking: Always utilize wedgelocks (TPA) to prevent terminal back-out under vibration.
  • Sealing Integrity: Ensure wire insulation outer diameter matches cavity seal specifications, and seal all unpopulated cavities with dedicated blind plugs.
