Rev : 1 | Rev date : 04 Oct 2023
These high-performance coaxial cable connectors are characterized by excellent gas tightness and extremely low losses. The connectors can be installed with basic hand tools. Tab flange of outer connection and use of o-ring sealing simplifies installation of the connector.
The connectors are fully tested for mechanical and electrical compliance to specifications.
They have excellent electrical values and provide outstanding performance for the most demanding applications. The design provides maximum sealing integrity and gas tightness.

FEATURES / BENEFITS

  • Easy installation utilizing only basic hand tools.
  • Tab flare of outer contact attachment means quick and simple installation.
  • No need for sealing compound. The connector is ready for pressurization immediately after installed to the cable.
  • Excellent gas tightness. Overpressure for increased voltage handling is maintained throughout the system.
  • Outstanding VSWR performance improves overall system performance.
  • Totally waterproof, assures safe, long term operation in the harshest of environments. 
  • RoHS (EU) and CRoHS (China) compliant, can be used on a global basis.
