Product description
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 mainly used 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.
