R-TNC, R-SMA, R-BNC

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 and are available in three different series: R-SMA connectors are supplied with a threaded coupling, are vibration resistant and can be used up to frequencies of over 6 GHz (depending on type). The impedance is controlled at 50 Ω. R-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. R-BNC connectors are supplied with a bayonet coupling. Connector designs are available with crimp cable termination. Mating face sealing for series R-SMA and R-TNC between plug and jack (mated) meet IP 68 requirements; series R-BNC meets IP 54 requirements.
