AMPHENOL RF 315431 BNC Connector
Amphenol's BNC connectors, like the 31-5431, are miniature RF connectors developed in the late 1940s. They offer a quick and reliable bayonet coupling mechanism, making them ideal for applications requiring frequent connections and disconnections. Available in 50Ω and 75Ω impedance designs, these connectors cater to a wide range of systems. They are commonly used in test instrumentation, medical equipment, antennas, base stations, and cable assemblies, providing low reflection and consistent performance. Military-grade connectors adhere to MIL-C-39012 specifications, ensuring high reliability and performance.
