BNC Adaptor

BNC Connector (acronym of " Bayonet Neill-Concelman") is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. 

mating is fully achieved with a quarter turn of the coupling nut. BNC Connectors are manufactured for 50Ω and 75Ω impedance applications, such as Radio -frequency equipment, Television, test instruments and video signals (CCTV). The BNC was originally designed for military use and has gained wide acceptance in video and RF applications to 2 GHz. Typically the male connector is fitted to a cable, and the female to a panel on equipment.
