RP-Triax Connectors

RP-Triax Connectors

Amphenol Triax connectors are used in applications where maximum RF shielding and minimum noise radiation is required. Triax are engineered for superior performance, and are built to the highest quality standards.

They are the perfect solution for harsh environments with high temperatures. They can also be tested and approved for use in the nuclear reactor chambers.

Features and Benefits
  • 5000V peak with Teflon insulators allows for high temperature applications
  • Solder/Clamp assembly procedure requires no special crimp tools
  • Precision machined for consistent performance provides dependability
  • Specialty insulators available for nuclear standards
  • Available in ⅞-20 and 11/16-24 threading, Triax C, Triax BNC and Triax TNC coupling
  • Industrial
  • Military
  • Instrumentation
