The BNC75 Series connector is a 75 Ohm BNC type connector designed to be compatible with standard 50 Ohm BNC connectors. It features an easy-to-use bayonet lock system for quick and secure mating. This connector is suitable for coaxial cables with diameters ranging from approximately 3mm to 6mm. It is reliable at high frequencies, with 12G products supporting 12G (UHD)-SDI (SMPTE ST-2082) transmission. The series complies with Japan Electronics and Information Technology Industries Association (JEITA RC-5233) specifications.
