BNC

The BNC connectors incorporate a bayonet lock interface which provides a rapid and reliable connection.

This connector range is suitable for the standard ranges of flexible and semi-rigid cables and is also available in PCB and panel mount versions.

The characteristic impedance of the BNC coaxial connectors is 50 or 75 ohm.

BNC connectors meet the specification of IEC 169-8 and
MIL-C-39012.
