BNC Jack for RF Signal Paths — 50 Ohm, 4 GHz
The gold-plated phosphor bronze centre contact handles 500 mating cycles before the plating wear starts to shift contact resistance; for a BNC that is a solid field-service life.
Mounting and Termination — Bulkhead Kit with Hardware
Termination is solder cup on the centre contact and a solder shield connection; the installer tins the centre conductor and the braid, then solders each cup.
Ratings and Signal Integrity
Rated 500 V — the voltage limit is set by the air gap and PBT dielectric, not the contact spacing. The isolated feature (listed as a feature) means the shell is not tied to the centre contact path — the ground is carried through the panel mount and shield solder connection.
