The BNC series includes widely used coaxial connectors suitable for frequencies up to 4 GHz. They are characterised by a practical bayonet lock and are available in versions with 50-ohm and 75-ohm impedance values. The connectors are designed for flexible, semi-flex and semi-rigid cables. PCB connectors of this series are available as solder or press-fit types, while cable connections are made by crimping, clamping or soldering, depending on the design.
