AMPHENOL RF 31220N75 BNC Connector
Amphenol's 31-220N-75 BNC connector is a miniature, lightweight RF connector developed for applications requiring quick and reliable connections. It utilizes a bayonet coupling mechanism, allowing for easy mating and unmating with a quarter-turn of the coupling nut. Ideal for terminating miniature to subminiature coaxial cables, this connector is commonly used in test instrumentation, medical equipment, and various communication systems. Amphenol offers both 50Ω and 75Ω BNC connectors to meet diverse impedance matching needs, with options for crimp/crimp, clamp/solder, and field serviceable termination styles. Military grade connectors are produced to MIL-C-39012 specifications.
