R-SMA

The term "reverse-polarized connectors" is used when, for example, a standard cable plug has a central contact with internal polarity instead of a central contact with external polarity. Reverse polarization connectors are used mainly in WLAN applications and are available in three different series: R-SMA connectors are supplied with a threaded connection, resistant to vibrations and can be used at frequencies above 6 GHz (depending on the type). Impedance is controlled at the level of 50 ohms.
R-TNC connectors are supplied with a threaded connection, resistant to vibrations and can be used at frequencies above 6 GHz. Impedance is regulated at the level of 50 ohms.
R-BNC connectors are supplied with a bayonet connection. There are possible versions of connectors with cable crimping.
