Allen-Bradley 800FP-MT44PX01 Programmable Logic Controller Module

The Allen-Bradley 800FP-MT44PX01 is a 22 mm twist-to-release emergency stop pushbutton designed for rugged control panels and safety circuits. It features a red 40 mm diameter mushroom cap and a 22.5 mm mounting hole, compatible with Type 4/4X/13 enclosures and rated for IP66/IP69K. It provides one normally closed contact, with a contact block rated up to 600 V (A600, Q600) and 10 A, terminated via screw terminals. The E-stop is non-illuminated—no illumination module or lamp is included—and the twisting-to-release actuator unlocks by turning, rated for at least 300,000 cycles. Surface mounting is supported, and the unit is CE certified, originating from China. This product is intended for use as an emergency stop in machinery such as conveyors, presses, and packaging lines, where a resettable stop is required to safely halt equipment and protect operators. Operating temperature is -25 °C, and humidity is up to 95% RH between 25–60 °C, with storage down to -40 °C. The MT44PX01 designation identifies a 40 mm actuator with a 22 mm grip and a standard NC contact configuration in the Allen-Bradley 800F pushbutton family.
