The nickel-plated zinc alloy body and gold-plated brass centre pin handle the signal path, with a PTFE dielectric maintaining the 75 Ohm characteristic through the interface. This plug is listed for AT&T 735, 735A, and Belden 735A1 cable types — a 75 Ohm dual-shield or tri-shield coax with a solid dielectric. The shield termination is crimp, not clamp or solder, so the correct crimp die for the cable OD is required. The 45° angle mounting option in the free-hanging (in-line) orientation allows the cable to exit at an angle from the panel, useful in tight rack enclosures where a straight plug would strain the cable. ## RF Performance and Mechanical Life Rated to 3 GHz maximum frequency with 0.2 dB insertion loss — typical for a 75 Ohm BNC in video distribution; above 3 GHz the return loss climbs and the connector becomes a mismatch.","metaTitle":"Amphenol RF 031-80405 BNC Plug, 75 Ohm, 3 GHz, 500 Cycles","metaDescription":"Amphenol RF 031-80405 BNC plug, 75 Ohm impedance, 3 GHz max, 500 mating cycles.
