MCX

The MCX connectors incorporate a 'snap on' latching action for easy and fast connection. Compared to SMB connectors, they offer 30% reduction in installation space and weight. The frequency range is up to 6 GHz.

This connector family is suitable for the standard range of flexible and semi-rigid cables as well as for PCB and panel mounting.

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

MCX coaxial connectors meet the specification of IEC 1169-36 and CECC 22220.
