BNC
Amphenol
Description
Developed in the late 1940’s, the BNC is a
miniature version of the Type C. BNC stands for
Bayonet Neill Concelman and 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.
Primary Applications - Ideally suited for cable
termination for miniature to subminiature coaxial
cable (RG-58, 59, to RG-179, RG-316, etc.)
Features/Benefits
• Bayonet coupling mechanism provides quick
mating and unmating.
