The 132168RP is an SMA plug to SMA reverse polarity plug adapter designed for RF applications. It is constructed with a durable, gold-plated brass housing and a natural Teflon insulator for reliable performance. The contact pin is made from gold-plated beryllium copper to ensure a stable electrical connection. This in-series adapter is used to interface between standard and reverse-polarity SMA connectors, which are often found in Wi-Fi hardware and other wireless communication systems.
