The Hirose BNC75 Series offers 75 BNC connectors designed to be compatible with standard 50 BNC connectors. These connectors feature an easy-to-use bayonet lock system for secure and convenient mating. They are suitable for coaxial cables with diameters ranging from approximately 1.5 to 6, such as 1.5C-QEV.CW. The series complies with Electronic Industries Association of Japan's temporary specifications (EIAJ RCX-5233) and is ideal for applications requiring reliable 75 impedance, including network analyzer test sets and test port terminations.
