The term “reverse-polarised connectors” is used where, for example, a standard cable plug has a female centre contact, instead of a male centre contact. Reverse-polarised connectors are very popular in WLAN applications.

TNC connectors are supplied with a threaded coupling, are vibration resistant and can be used up to frequencies of over 6 GHz. The impedance is controlled at 50 Ω.

Mating face sealing for TNC between plug and jack (mated) meet IP 68 requirements.
