MCX Connectors
   
MCX Connectors MCX connectors conform to the European CECC 22220 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.
