The BNC series is the most commonly used coax connector. With its bayonet coupling mechanism this
connector can be used up to 4 GHz. Both 50 and 75 Ω impedances are available. Connector styles are
available for flexible, conformable and semi-rigid cable types. Versions of the BNC connector are available for
mounting to printed circuit boards using both through-hole soldered and through-hole press-fit techniques. Both
crimp and clamp cable termination processes are used for this series. BNC connectors are used for signal,
data and video transmission applications.
Mating face sealing for BNC connectors between plug and jack (mated) according to IP 54. The classifications
are general statements for the relevant series. Individual connectors may deviate from the values shown. If in
doubt, please consult our engineers.
