The Amphenol 132195RP is a reverse-polarity SMA (RP-SMA) plug with a female socket center contact, built for RG-55, 142, 223, and 400 series coax cables. The reverse-polarity interface means the center contact is reversed compared to standard SMA — a female socket on the plug side — so it mates with an RP-SMA jack that has a male pin. Rated for 50 Ohm impedance up to 12.4 GHz, with a 500 V voltage rating and 500 mating cycles.
This plug is designed for RG-55, 142, 223, and 400 cable groups — the crimp ferrule and solder center contact are sized to match those specific coax diameters and dielectric dimensions. The shield terminates via crimp, the center conductor solders into the beryllium copper contact. For a clean RF assembly, strip the cable per the manufacturer's dimensions for the chosen coax type; the PTFE dielectric supports the impedance through the transition. The threaded coupling nut provides a vibration-resistant mate, and the gold-on-gold contact interface holds up through the rated 500 mating cycles without signal degradation.
