Amphenol's TNC connectors, like the 031-2367-RFX, are miniature, threaded, weatherproof units developed in the late 1950s. Designed as a threaded version of the BNC, they feature screw threads for mating and maintain a constant 50Ω impedance, suitable for DC to 11 GHz applications. These connectors are ideal for commercial applications where cost-effectiveness is important, offering a reliable solution for antennas, base stations, cable assemblies, and more. They are available in standard and reverse polarity interfaces, ensuring compatibility and preventing mismating.
