The bayonet lock provides quick, secure mating, and the nickel-plated brass body with a gold-plated centre contact supports up to 500 mating cycles. For new builds, evaluate the 75 Ohm BNC product line from Amphenol RF for a form-fit-function match; the 031-70238 is still a viable option for legacy repairs or BOM fills where the cable group and 75 Ohm impedance are locked. This plug is engineered for AT&T 735, 735A, and Belden 735A1 cable groups — the crimp dimensions and ferrule are matched to those dielectric diameters and braid configurations. The centre contact is crimped, and the shield is terminated via a separate crimp ferrule. ## Electrical and Mechanical Ratings The 500 V voltage rating and 4 GHz frequency ceiling cover most baseband video and low-power RF links.","metaTitle":"Amphenol RF 031-70238 BNC Plug, 75 Ohm, 4 GHz, NRND","metaDescription":"Amphenol RF 031-70238 BNC plug, male pin, 75 Ohm, 4 GHz max, 500 V.
