MCX Connectors

MCX ConnectorMCX connector has smaller size compared with some RF connectors like SMA connector, SMB connector. MCX connector is designed to have snap-on mating. Besides, MCX connector series are available for RF cables type, PCB type and SMT type. MCX connector commonly is used for 0~6GHz.

Wellshow Technology manufactures various MCX connectors and custom MCX RF cable assemblies in Taiwan. We can provide good quality products in short time and welcome OEM or customized RF connector. Contact us by email or call us 886-2-24270488 to start business!

MCX Connector Series

All MCX Connector

MCX Plug Connector

MCX Jack Connector


The MCX coax connector series was developed in 1980’s confirm to the European CECC 22220 specification. MCX series has snap-on coupling mechanism design and offer broadband capability through 6 GHz.
MCX connector are less than SMB approximately 30% in mounting space. 50 ohm and 75 ohm connectors are available.

MCX connector’s snap-on mating design reduces installation time and MCX connectors are commonly used in GPS, Wireless LAN(W-LAN), GMS and Telecommunications.
