Allen-Bradley 800EP-MJT4 Mushroom Button Operator

Allen-Bradley 800EP-MJT4 Mushroom Button Operator is a rugged, red, non-illuminated mushroom-style 22.5 mm control actuator from Rockwell Automation’s 800EP family. The MJT4 variant is a push-pull operator designed for panel-mount installations, providing a large, tactile actuator that’s easy to identify and operate in demanding industrial environments. This non-illuminated head is color-coded red for clear signaling in control circuits and is typically used as a manual input in automation lines where a reliable, decisive action is required. As part of the 800EP portfolio, the MJT4 integrates with standard 22.5 mm back-of-panel components and mounting schemes within Allen-Bradley control architectures, ensuring compatibility with compatible frames, housings, and related 800EP operators. The combination of red mushroom head, non-illuminated operation, and a 22.5 mm footprint makes it a common choice for stop or control inputs on machinery and conveyors, where quick recognition and robust mechanical action are important for operator safety and process reliability.
