The bayonet lock provides quick, secure mating, and the gold-plated center contact ensures low and stable contact resistance over 500 mating cycles. ## Crimp Termination and Cable Compatibility The cable group is specified for Belden 4505P — a 75 Ohm precision video coax. Using a different cable changes the crimp die size and the impedance match, so stick with the listed cable or verify the crimp dimensions against the manufacturer's drawing. ## Mating and Mechanical Fit Mating a 75 Ohm plug to a 50 Ohm jack creates a reflection at the interface that degrades return loss. The bayonet lock engages with a quarter-turn, and the nickel-plated phosphor bronze body resists corrosion. The free-hanging (in-line) mounting is typical for cable assemblies; no panel cutout or bulkhead hardware is needed.","metaTitle":"Amphenol RF 031-70572-12G BNC Plug, 75 Ohm, 12 GHz, Crimp","metaDescription":"Amphenol RF 031-70572-12G BNC plug, male pin, 75 Ohm impedance, 12 GHz max frequency, crimp termination for Belden 4505P.
