This is a bayonet-lock BNC, rated to 2 GHz with a 0.15 dB insertion loss, and built for 500 mating cycles. The body is zinc die-cast with a nickel finish, the centre contact is brass with gold plating, and the dielectric is polyethylene. It's specced for RG-179, 179A, 179B, 187, and 187A cable groups. Both the shield and the centre contact are crimp-terminated. The cable group is RG-179, 179A, 179B, 187, and 187A — these are the 75 Ohm, small-diameter coaxial cables common in video and broadcast patch panels. The kit includes the ferrule for the shield braid and the sleeve for the jacket, so the crimp tooling just needs the right die for the RG-179 OD. The 75 Ohm impedance and 2 GHz frequency ceiling are the defining specs — this is a video/broadcast BNC, not the 50 Ohm version used in RF test equipment or telecom. The 500 mating cycles are good for a field-service connector; the gold-plated centre contact handles the repeated connect-disconnect without fretting. The 500 V rating is the dielectric withstand between centre and shield, not a continuous power rating — this is a signal connector, not a power interconnect.","metaTitle":"TE Connectivity 5221185-8 BNC Plug, 75 Ohm, 2 GHz, Obsolete","metaDescription":"TE Connectivity 5221185-8 BNC plug, male pin, 75 Ohm, 2 GHz, crimp termination for RG-179 cable.
