BNC

Developed in the late 1940's as a miniature version of the Type C connector, BNC stands for Bayonet Neill Concelman and is named after Amphenol engineer Carl Concelman. The BNC connector is a miniature quick mating and de-mating RF connector. It features two bayonet lugs on the female connector; mating is achieved with only a quarter turn of the coupling nut.

SV Microwave's 50 Ohms BNC series connectors are miniature and lightweight. They are designed to operate at a frequency of DC to 11 GHz and typically yield low reflection through 4 GHz. BNC connectors can accommodate a large variety of RG and industry standard cables. BNC connectors are ideally suited for cable termination for miniature to subminiature coaxial cable (RG-58, 59, to RG-179, RG-316, etc.)
