Amphenol's BNC connectors are miniature, lightweight RF connectors developed in the late 1940s. They offer a quick-connect/disconnect design with a bayonet coupling mechanism, making them ideal for applications requiring frequent connections and disconnections. These connectors are commonly used with miniature to subminiature coaxial cables like RG-58, RG-59, RG-179, and RG-316. Amphenol offers both 50Ω and 75Ω BNC connectors to meet diverse impedance matching needs, catering to applications in telecommunications, broadcast, instrumentation, and medical equipment. Military-grade connectors are produced to MIL-C-39012 specifications, ensuring high performance and reliability.
