Product details

50 Ohm RP-TNC Plug for RG-Type Cables, 11 GHz

The Amphenol 122372RP is a reverse-polarity TNC (RP-TNC) plug with a female socket center contact, designed for field termination onto common RG-type coaxial cables. It ships as a complete three-piece kit: the connector body, the crimp contact, and the ferrule, so you're not hunting for loose parts at the bench.

This plug is listed for RG-55, RG-223, and RG-400 cables — common 50 Ohm double-shielded types used in comms and instrumentation.

Construction and RF Performance

The body is machined brass with a nickel finish — corrosion-resistant for outdoor or industrial cabinet use.
