Product details

75 Ohm BNC Jack — the video/telecom signal path connector

The 031-221-75RFX: The bayonet lock gives 500 mating cycles — enough for a patch panel or test rack where the connector gets reconnected regularly. The kit ships with 4 pieces: the connector body, a locking ring, a lockwasher, and a nut — everything needed to mount it through a bulkhead panel. The shield terminates by soldering to the body.

Panel-mount bulkhead — the hardware is in the bag

This is a rear-side-nut bulkhead mount: the connector body slides through the panel hole from the outside, the lockwasher and nut tighten from the inside. The included locking ring secures the bayonet interface. The nickel-plated brass body gives good RF shielding and corrosion resistance for indoor equipment racks and control cabinets. The solder cup termination is field-serviceable — you tin the center conductor, solder it into the cup, and solder the braid to the shield body. No crimp tool needed.
