●BNC series is most widely used as 50Ω coaxial cable connectors.
●This series is used specially for interface of frequent  fit-in/pull-out  instruments by small  size/
light weight bayonet lock mechanism.

Note:
BNC  series  is  intermateable  with  BNC75  series. (75Ω group)
●If 75Ω cable is used for this series, the frequency to be applied must be below 200MHz.   For  more  than  200MHz,  BNC75  series  must  be used.
