MCX and MMCX Connector Specifications


Coaxicom MCX Series Connectors feature reliable Snap-On mating. They are 30% smaller than the SMB series and offer an excellent combination of performance, size and weight. They operate to a higher frequency than the SMB (6 GHz compared to 4 GHz). These features make the MCX series ideal for applications w here performance is critical and space is limited. The standard MCX series has a 50 Ohm impedance. For 75 Ohm connectors, add “-75” suffix to the catalog part numbers

MCX Connectors have widespread applications in GPS, data systems and automotive and wireless communications, as well as for laboratory test and measurement use. They are readily available for flexible and semi-rigid cables as shown below. Interface dimensions as well as all other applicate requirements are in accordance with MIL-PRF-39012 and other military standards where the needs exists.


Coaxicom MMCX Series Connectors are intended for applications that require the smallest possible coaxial interact to be used with standard miniature single and double shielded flexible and semi-rigid cables. The MMCX series is a scaled-down version of the MCX series. It features the same reliable Snap-On mating and performance to 6 GHz, but is smaller. Its low profile (0.138 total height above the board, compared to typically 0.236 for the MCX) PWB connectors makes the series the best choice for cellar phones, CPS, and other size-critical applications.

Coaxicom offers both the MCX and the MMCX in versatile edge mount jack receptacles that accommodate board thicknesses from .031″ to .063″. The MMCS IM246EM-1 is unique in that it mounts with the connector mating end flush with the board edge for enhanced space savings and design flexibility.


MIL-PRF-39012, MIL-A-55339, MIL-C-83517 and MIL-STD-348 as applicable.
