A [BNCConnector BNC-Connector] is a [CoaxialCable coaxial cable] connector. While there are a handful of different [BNCConnector BNC] flavours, they all provide the same high quality connection. Because of the high quality of [BNCConnector BNC-Connectors], they are extremely common in commercial use (Telecommunications, Video broadcasting, etc), and on medical and test equipment, where performance is critical.



"BNC" stands for "Bayonet Neill Concelman", and is named after engineer Carl Concelman who invented the connector in the late 1940's. [BNCConnector BNC-Connectors] mate using a 2-stud bayonet coupler, requiring only a quarter-turn of the connector.



Many people may know the 50 Ohm version of [BNCConnector BNC-Connectors] from an old [Ethernet] standard called [10base2]. Other people may know the 75 Ohm version from high-end [DVD] or older [VHS] players. [BNCConnector BNC-Connectors] these days are often rated to a maximum frequency anywhere between 1 GHz and 10 GHz.



In [WLAN Wireless LANs], [RPBNCConnector Reverse-Polarity BNC Connectors] are more common, and [RTBNCConnector Reverse-Thread] versions also exist, although are extremely rare. An alternative to the [BNCConnector] is the [TNCConnector TNC-Connector].
