MMCX Connector Definition

Date Updated: September 10, 2019 FAQ #4159


I have heard the connectors used on Shure earphones called "MMCX."   Do these letters meaning anything, besides 2,110 in Roman numerals?


MMCX = Micro Miniature CoaXial connector.  The connector on the earphone cable is a male plug with a custom plastic overmold.


This connector was developed by Amphenol. It is available from Digi-Key as part ACX1276-ND.
