What is a BNC connector?

The BNC connector (Bayonet Neill-Concelman connector) is one of the connectors for connecting a coaxial cable. A lock called the Bayonet mount allows quick and easy attachment / detachment by rotating the ring at the tip of the connector. Suitable for use with thin coaxial cables, the characteristic impedance is 50Ω or 75Ω. It is widely used as a signal line for video equipment, communication equipment, and measuring equipment.
