Product details

BNC Plug for RG-58 and Similar Cables, 50 Ohm, 4 GHz

The 031-3301: It is part of the 031-33 series, a standard 50 Ohm BNC interface for test equipment, telecom, and instrumentation.

This plug accepts RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cables — the common 50 Ohm flexible and semi-rigid types for short-run RF links. The centre contact is soldered, and the shield is terminated with a clamp that grips the braid.

The connector is rated weatherproof, so it can be used in outdoor or damp enclosures as long as the mating receptacle is similarly sealed. Gold on the centre contact supports the 500-cycle mating life without fretting corrosion at the signal path.
