Amphenol's 000-5275 BNC connector is a miniature, lightweight RF connector developed in the late 1940s. It utilizes a bayonet coupling mechanism for quick and reliable mating and unmating, making it ideal for cable termination in miniature to subminiature coaxial cable applications (RG-58, 59, to RG-179, RG-316, etc.). Available in both 50Ω and 75Ω impedance options, these connectors cater to a wide range of system requirements and are commonly used in test instrumentation, medical equipment, antennas, and broadcast applications. Military-grade versions adhere to MIL-C-39012 specifications, ensuring high performance and reliability.
