Product details

Why the polarity swap matters for your RF line

The Amphenol RF 112514RP is a reverse-polarity BNC (RP-BNC) plug with a female center socket, intended for applications where standard BNC polarity is deliberately avoided — common in wireless infrastructure, ISM-band radios, and certain Wi-Fi access points where the equipment maker wants to prevent accidental mating with a standard BNC antenna.

Cable prep and crimp fit

This plug is designed for RG-55, RG-142, RG-223, and RG-400 coax — the crimp ferrule and center contact are sized to those specific cable dielectrics and braid diameters.

Frequently asked questions

What cable groups are compatible with 112514RP?

The 112514RP is designed for RG-55, RG-142, RG-223, and RG-400 coaxial cables. Using a different cable group will change the impedance and may compromise the crimp retention.

Is 112514RP a male or female connector?

The 112514RP is a reverse-polarity BNC plug with a female center socket. It mates with a standard RP-BNC jack (which has a male center pin).
