Product Description
4-Pin Male Panel Connector for Radio Microphone and Electrical
The CMC-4MP is a rugged 4-pin circular metal panel-mount connector designed for microphones, communications equipment, and low-voltage electrical applications. This GX16-4-style connector features a 16 mm threaded coupling system that provides a secure, locked connection resistant to vibration and accidental pulling.
It is well suited for Ham Radio and CB Radio microphone applications, as well as control panels, electronic equipment, test equipment, and other low-voltage applications requiring a durable 4-conductor connection.
