BNC RF connector is a miniature version of the Type C. BNC (Bayonet Navy Connector) has a twist-snap connection. It is available in 50 Ohm and 75 Ohm impedance versions. The BNC product line is a miniature quick connect/disconnect RF connector.
It features two bayonet lugs on the female connector; mating is achieved with only a quarter turn of the coupling nut. BNC connector ideally suited for cable termination for miniature to subminiature coaxial cable(RG-58,RG-316,etc.) Interface dimensions conformable to the Standards: IEC 169-8 CECC 22120 MIL-C-39012,BNC interface MIL-STD-348A/301 BS 9210 N 004 Features/Benefits Bayonet coupling mechanism provides quick mating and unmating.
50 and 75 Ohm impedance designs allow customer to match impedance to system requirements. 50 and 75 Ohm connectors are intermateable to ensure nondestructive mating.
