The MCX (Micro Coaxial) series is a 50 Ω series with broadband capability ranging from DC to 6 GHz. In addition, the MCX series features secure, fast and easy snap-on/ snap-off coupling. MCX connectors were introduced in the 1980s and conform to the European CECC 22220 spec.

This series provides designers with options where weight and physical space are limited. 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.
