MCX Type RF Connectors

Please note that you only need to register as a member for the first time.

MCX (Micro Coaxial Connectors) are small snap-on type rf connectors approximately 30% smaller than SMB type, enabling compact, space-saving mounting. They are used in communication systems, GPS, medical equipment, and vehicle antennas.

Some MCX,MMCX type RF connectors are available for purchase from Digi-Key.

No cables with MCX connectors are available in stock.

Trivia: About Cables

MIL Standard
Compliant with US military standards for cables. Begins with the initials "RG" and is also called Mil-Spec.

Since this connector is smaller than the SMB connector, high-density mounting can be achieved in a small space, not only for wiring in equipment but also for connection between subassemblies that make up the equipment and between equipment.

Compared to the threaded coupling method, the snap-on coupling method is used, making connection easier. Since the connectors can be coupled by simply pushing the connectors together, this method is suitable for locations where tightening screws is difficult and space is limited.

MCX connectors are also available in 75 Ω as well. MCX 75 Ω connectors are recommended for video, broadcasting, home appliances, and factory automation equipment with lower operating frequency bands.
