TNC Connectors

TNC Connectors

The TNC connector series is a miniature, threaded weatherproof series with a constant 50 Ω impedance and a frequency range of DC to 11 GHz. The TNC series shares its contact design with the BCN series, utilizing a threaded coupling nut for secure mating and higher frequency performance than the BNC.

TNC connectors are produced with standard and reverse polarity. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors. Amphenol accomplishes this by inserting female contacts into plugs and male contacts into jacks to ensure quality. Other manufacturers may use reverse threading to accomplish reverse polarity keying.

As a result of their versatility and durability, TNC connectors are ideal for a variety applications.
