The kit ships as three pieces — one connector body, one centre contact, and one ferrule — so a single order code covers the terminated cable-end assembly. This plug accepts RG-55, 142, 223, and 400 cable groups. The shield termination is crimp; the centre contact can be crimped or soldered. For a field-terminated BNC that holds impedance through the transition, match the cable group listed — the dielectric and centre-conductor dimensions are tuned to 50 Ohm for those types. ## Mating Cycles and Contact Plating The bayonet lock gives a positive quarter-turn mate without tools.","metaTitle":"031-4427 Amphenol RF BNC Plug Male Pin, 50 Ohm, 4 GHz","metaDescription":"Amphenol RF 031-4427 BNC plug, male pin, 50 Ohm, 4 GHz max.
