MCX (Micro Coaxial) connectors are miniature RF solutions designed for applications up to 6 GHz. Featuring a snap-on coupling mechanism, these compact connectors offer reliable performance in space-constrained devices. Commonly used in GPS systems, wireless communications, and IoT devices, MCX connectors provide excellent electrical characteristics while being 30% smaller than SMB connectors. Their push-pull design enables quick connections in high-density installations.

Category Insights

MCX connectors perform optimally up to 6 GHz, making them suitable for most wireless applications including WiFi, cellular, and GPS systems. While they can function beyond this range, signal integrity may degrade compared to larger connectors, with increased insertion loss at higher frequencies.
While both are miniature connectors, MCX is slightly larger than MMCX (Micro-Miniature CX). MCX offers better mechanical strength with its 3.5mm diameter versus MMCX's 2.5mm. However, MMCX is preferred for ultra-compact devices as it supports similar frequencies but in a smaller footprint.
Standard MCX connectors are not waterproof, but IP67-rated versions are available for outdoor applications. These weather-resistant variants feature sealed designs with silicone gaskets and corrosion-resistant plating, making them suitable for automotive telematics and outdoor wireless equipment.
MCX connectors are widely used in:
  • GPS receivers and antennas
  • Cellular modems and IoT devices
  • Set-top boxes and TV tuners
  • Test and measurement equipment
  • Medical monitoring devices: Their compact size makes them ideal for PCB-mounted applications where space is limited.
MCX connectors typically withstand 500+ mating cycles, significantly more than MMCX connectors. Their snap-on mechanism provides secure connections while allowing quick disconnection. For vibration-prone applications, look for versions with positive locking features or consider SMB connectors for more robust connections.
