MCX
MCX Connectors
Description
MCX connectors conform to the European CECC 22000 spec and were introduced in
the 1980’s. While the MCX uses identical inner contact and insulator dimensions as
the SMB, the outer diameter of the plug is .140 inches, which is 30% smaller than the
SMB. This series provides designers with options where weight and physical space are
limited. MCX provides broadband capability though 6 GHz with a snap-on connector
design. A range of connectors are available, including printed circuit board and cable
connectors and they are all used in the Automotive, Wireless LAN, Broadband and
Wireless Infrastructure markets.
