BNC cable - what is it?
You will come across BNC cables in high-frequency, video and audio technology. We'll explain what BNC is about.
What is a BNC cable?
BNC cables have certain characteristics and areas of application. The following key data can be used to describe BNC. You can find application examples and photos in the following picture gallery.
- BNC is a widely used coaxial cable, similar to a DVB-C antenna cable.
- BNC cables are used particularly in radio and video technology.
- BNC is designed with a characteristic impedance of 50 or 75 ohms for high-frequency signals up to 4 or 2 GHz.
- The bayonet catch holds the connector in place even when the tension is high. Thanks to the widespread T and L pieces, you can also attach BNC to the back of devices to save space.
- BNC was developed by Paul Neill and Carl Concelman based on the C-connector by Octavio M. Salati and patented in 1951.
- The abbreviation probably stands for "Bayonet Neill-Concelman", but the terms "Bayonet Nut Connector", "Bayonet Nail Connector", and "British Naval Connector" as well as some others are used occasionally.
In the next practical tip we will show you how to cleverly stow your cables.

Due to the bayonet lock, the BNC connector must always be inserted in the correct orientation.
After a small turn, the connector engages and secures the connection.
BNC is also used in audio technology, for example in microphones with a BNC connector. You can find out what you should consider when buying a microphone in [[//praxistipps.chip.de/mikrofon-kaufen-welches-rauche-ich_37245|diesem]] practical tip.
The cable goes into the ICP connector on the preamplifier. ICP provides a power supply and signal transmission over the same line - in contrast to phantom power at [[//praxistipps.chip.de/iffere- Zwischen-klinke-und-xlr_16794|XLR]].
Digital signals are also transmitted via BNC
for example Word Clock for synchronizing devices.
BNC can be converted to an unbalanced jack using an adapter
or to cinch.
BNC and L plugs are typical of BNC, so that cables can be connected in a space-saving and kink-proof manner even behind devices and at angled positions.
