Durable Brass and Beryllium Copper Twinax Triax Connectors Bel Fuse LPTWA-78 for Digital Data Bus
Cinch Connectivity Solutions: Twinax/Triax Connectors
Cinch Connectivity Solutions, a division of Cinch Connectivity Solutions, offers a comprehensive range of Twinax/Triax connectors designed for high-performance applications in military, space, and testing environments. With a legacy of over 100 years in manufacturing, Cinch provides reliable, high-quality connectors and cable assemblies. Their Twinax/Triax connectors are engineered to meet or exceed stringent military specifications, including MIL-C-49142, with some series developed directly from Trompeter's concentric twinax/triax connector designs. These connectors are ideal for applications requiring noise-free guarded circuits, digital data bus, video pairs, MIL-STD-1553B (airborne/ground, primary/redundant), and baseband circuits. Key features include machined parts to close tolerances, brass bodies with nickel plating, and heat-treated beryllium-copper contacts with gold plating for durability and conductivity.
