AMPHENOL RF 3156331010 BNC Connector

Amphenol's 31-5633-1010 BNC connector is a miniature, lightweight RF connector developed for quick and reliable connections. Featuring a bayonet coupling mechanism, it allows for easy mating and unmating with a quarter-turn of the coupling nut. Designed to accommodate a wide range of RG and industry-standard coaxial cables, this connector is commonly used in applications such as test instrumentation, medical equipment, antennas, base stations, and cable assemblies. Amphenol offers both 50Ω and 75Ω BNC connectors to meet diverse impedance matching requirements, ensuring low signal distortion and optimal performance. Military-grade connectors are produced to MIL-C-39012 specifications, while commercial-grade connectors are easily identifiable with the 'RFX' designation.
