RP-MCX Connectors

The MCX (Micro Coaxial) series is available with 50 or 75 ohm options, and has 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.

A robust range of connectors are available, including printed circuit board and cable connectors, as well as 12G optimized products.

Features and Benefits

  • Available for 50 or 75 ohm applications
Applications
  • WLAN
  • Global Positioning System (GPS)
  • PC/LAN
  • Automotive
  • Base Station
  • Head End Equipment
  • Radios
  • Wireless/Network Antenna
  • Instrumentation
  • Telecommunications
