TNC Series RF Connectors

TNC RF Connector

RF Connectors > TNC Series RF Connectors

Description

Developed in the late 1950’s, the TNC stands for Threaded Neill Concelman and is named after Amphenol engineer Carl Concelman. Designed as a threaded version of the BNC, the TNC series features screw threads for mating. TNC are miniature, threaded weatherproof units with a constant 50 Ω impedance and they operate from 0 - 11 GHz.

There are two types of TNC connectors: 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. Other manufacturers may use reverse threading to accomplish reverse polarity keying.

Features & Benefits

  • Threaded coupling interface ensures connector will not de-couple in vibration-intensive applications
  • Many TNCs are recognized under the component program of Underwriter’s Laboratories and have undergone stringent testing from an independent laboratory
  • Performance from 0 - 11 GHz operations in many applications
