50 Ohm BNC Jack for RG-58 Cable Assemblies
The 000-36800-RFX: The 50 Ohm impedance matches the standard for test equipment, networking gear, and RF instrumentation, so this jack belongs in a 50 Ohm signal chain, not a 75 Ohm video or broadcast line. Rated to 4 GHz, it covers the full BNC band with headroom above the 2-3 GHz ceiling many economy BNCs hit.
This jack is built for the RG-58 cable group — RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. The shield termination is a crimp ferrule over the braid; the center contact crimps onto the signal conductor. For a field-service or production harness shop, this means one crimp tool handles both operations if the die set matches the contact and ferrule dimensions.
Bayonet Lock and Mating Cycles
The fastening type is a bayonet lock — the standard BNC push-and-twist coupling. It mates with any 50 Ohm BNC plug (male) that has the standard bayonet pins. The 500-cycle rating is typical for a gold-plated BNC; the nickel body finish and brass shell hold up to repeated connect-disconnect in test-lab or field-service use.
