  • EMI Shielding: solid metal-to-metal coupling, grounding fingers, electroless nickel plating, and thicker wall sections provide superior EMI shielding capability of 65dB minimum at 10 GHz
  • Withstands High Vibration: operates under severe high temperature vibration, through 200°C
  • Withstands High Impact Shock: excellent resistance shock with no electrical discontinuity and no disengagement of the mated connectors
  • Contact Protection: recessed pins in this 100 % scoop - proof connector minimize potential contact damage
  • No Lockwiring: unique, self - locking, quick coupling connector eliminates lockwiring
  • Quick Coupling: completely mates and self - locks in a 360° turn of the coupling nut
  • Moisture Resistance: improved interfacial seal design helps prevent electrolytic erosion of contacts


D38999/24WC35PN is currently used in many applications requiring extremely reliable interconnection. Because of its quick-mating, environmentally-sealed construction, triple-lead thread, self-locking coupling, and EMIRFI-shield this connector guarantees very high performance in most demanding applications. D38999/24WC35PN applications include:

  • Rockets and Space Vehicles
  • Military aircraft
