Amphenol's BNC connectors are miniature, lightweight RF connectors developed in the late 1940s. They offer a quick connect/disconnect mechanism with a quarter-turn bayonet coupling. Suitable for a wide range of applications including medical equipment, test instrumentation, antennas, base stations, and telecommunications, these connectors are available in various grades (military, industrial, commercial, and performance) to meet diverse system requirements. Amphenol offers both 50Ω and 75Ω BNC connectors, ensuring compatibility with different cable impedance needs. Reverse polarity options are also available for enhanced keying and safety.
