Multipin Circular MIC Connector - 2Pin Female

Multipin Circular MIC Connector - 2Pin Female

First used in the 1970s by Japanese radio manufacturers, for microphone connectors on Citizens Band and amateur radio equipment, these screw-on circular connectors were available with 2, 3, 4, 5, 6, 7, or 8 pins. They often were used for other purposes as well, such as Eastern Asian built soldering stations in 1990s.

These screw-locked connectors can be hard to find as they come under many generic names: "CB connector", "Mobile connector", "Microphone connector", "Power connector"—even sometimes misidentified as XLR connectors.

Even though this circular connector was largely standardized, there was no industry standard for pin assignments. Pin assignments to specific functions varied from manufacturer to manufacturer.
