TNC Connectors Introduction TNC Connectors Introduction

TNC connector is a threaded version of BNC connector, and the thread is 7/16”-28. With a medium size compared with SMA connector and N connector, TNC connector is commonly used in military radio telecommunication system.

Most TNC connectors are the 50 ohm type, but 75 ohm TNC connector also is available to join with 75ohm coaxial cable like RG6, RG59, RG179.

RP (Reverse Polarity) TNC is a variation of the TNC specification which reverses the polarity of the interface. This is usually achieved by incorporating the female contacts normally found in jacks into the plug, and the male contacts normally found in plugs into the jack. RP TNC connectors are widely used by WiFi or 2.4G WLAN equipment manufacturers.

Mechanical Feature:

TNC male

  • Inner thread of 7/16-28UNEF-2B on coupling nut, Inner diameter is from 10.135mm to 10.337mm
  • Male center contact
  • Silicon Rubber O-ring inside
  • Insulator nestles up throughout against outer contact, and an air gap between center contact and insulator for 50 ohm TNC male
  • Reduced insulator in mating end, and an air gap between center and outer contacts for 75ohm TNC male

TNC female

  • Outer thread of 7/16-28UNEF-2B with O.D. from 10.919~11.084mm for mating
  • Female center contact
  • Insulator surrounds female center contact wholly for 50 ohm TNC female
  • Part of female center contact doesn’t be surrounded by insulator and an air gap between center contact and outer contact for 75 ohm TNC female
