AMPHENOL RF 312318RFX TNC Connector
Amphenol's TNC connectors, like the 31-2318-RFX, are miniature, threaded weatherproof units developed in the late 1950s. Featuring a constant 50 Ω impedance and operating from DC to 11 GHz, they are ideal for commercial applications such as antennas, base stations, cable assemblies, and WLAN networks. The threaded coupling interface ensures stability in vibration-intensive environments, and reverse polarity options prevent mismating. These connectors offer a cost-effective solution for a wide range of RF applications.
