AMPHENOL RF 312381 TNC Threaded Connector
Amphenol RF's TNC connectors, like the 31-2381, are threaded connectors developed in the late 1950s. They feature a threaded interface for secure mating, particularly in vibration-intensive environments. These connectors offer a constant 50Ω impedance and operate from DC to 11 GHz, making them suitable for a wide range of applications including antennas, base stations, cable assemblies, cellular networks, instrumentation, and radar systems. They are available in standard and reverse polarity configurations to prevent mismating. Commercial-grade TNC connectors are easily identifiable with the 'RFX' designation and are ideal for cost-effective solutions in various commercial applications.
