Amphenol RF Twinax Connectors

Amphenol RF Twinax Connectors are used with 78Ω and 95Ω conductor cables and operate from 0MHz to 200MHz. Due to the improved shielding characteristic (>30dB), these connectors are used in balanced low level and high sensitivity circuits. Amphenol RF Twinax Connectors meet the applicable sections of MIL-DTL-3655. They feature keyway polarization to ensure system integrity and prevent signals from being mixed. These connectors are ideal for computer network applications.


  • Polarized key and keyway construction guarantees correct dual-contact mate
  • Large threaded connectors designed for rugged use
  • Crimp contacts for cost-effective installation
  • Clamp assembly allows quick assembly without requiring special tools
  • 2-stud bayonet design allows quick and easy coupling
  • Weatherproof when mated


  • Military/Aerospace
  • Computer networks/LAN
  • Industrial
