Trompeter / Cinch Connectivity Solutions Twinax/Triax Connectors
Trompeter / Cinch Connectivity Twinax/Triax Connectors are manufactured to meet or exceed Mil-Specs governing twinax connectors, specifically MIL-STD-1553B for airborne and ground checkout and MIL-STD-1760 external stores. Trompeter Twinax/Triax Connectors are designed for military applications to protect data signals from extraneous noise through non-signal-carrying shielding. These impedance-matched connectors improve the throughput and interference rejection of digital data transmission systems.
The TRB/TRT series is available as miniature 2-, 3-, and 4-lug, and push-on Twinax/Triax Connectors. TRB series Connectors are all metallic parts with fully enclosed outer conductors and center contacts plated with 50µ" gold. The TRS/TTM series is a subminiature concentric Twinax/Triax Connector for high-density and weight-reduction applications. These connectors are designed for blind mate rack and panel applications.
