This is a single-port, female socket with a bulkhead front-side nut mount and right-angle through-hole solder termination. The zinc die-cast body carries a nickel finish, the center contact is brass with gold plating, and the dielectric is polyethylene.
What the Ratings Mean
The 50 Ohm impedance and 4 GHz frequency ceiling define this as a standard BNC for RF instrumentation and telecom signal paths — the 4 GHz limit is the upper end of practical BNC bandwidth before mode conversion degrades the signal. The 500 V rating gives headroom for test equipment and broadcast video applications where isolation matters. 500 mating cycles is typical for a BNC bayonet interface; the gold-plated center contact supports repeated connect/disconnect without corrosion on the signal path.
Panel mount through a bulkhead with a front-side nut, right-angle PCB tails for the signal and shield solder termination. The bayonet lock provides quick mate and positive retention — standard for BNC. The board guide and isolated features noted in the series help with alignment and prevent ground loops in mixed-signal assemblies.
