What is a BNC connector?

A BNC, bayonet Neill Concelman, is the coaxial connector that locks with a quarter turn of its bayonet ring. It is made in 50 ohm and 75 ohm builds, and analog closed circuit television runs on the 75 ohm build. Match the impedance to the cable, and choose crimp or compression termination to suit the coax in hand.

Defined by IEC 61169-8, the sectional specification for the BNC interface, published by IEC.
