The centre contact is beryllium copper with silver plating, mated through a PTFE dielectric, and the brass body gets a nickel finish. ## Lifecycle Status — Obsolete, Sourced via Surplus The centre contact is solder-terminated — the beryllium copper pin solders to the cable centre conductor, and the clamp secures the braid. Panel mounting uses a flange with two holes; the bayonet coupling nut on the plug side locks with a quarter-turn. The PTFE dielectric keeps the impedance stable through the solder process, but take care not to overheat the centre pin during soldering — the PTFE can flow if the iron dwells too long.","metaTitle":"BNC-PJ-188/U(40) BNC Jack, 50 Ohm, 1 GHz, Obsolete","metaDescription":"BNC-PJ-188/U(40) BNC jack, 50 Ohm, 1 GHz max, 500 mating cycles, RG-188A cable, panel mount.
