Allen-Bradley 800FM-MT44 Push Button Mushroom Head

Allen-Bradley 800FM-MT44 is a 40 mm non-illuminated mushroom-head push-button operator from the 800F family, featuring twist-to-release action for emergency-stop control. The metal, round 40 mm operator carries a red mushroom cap (plastic) and includes a front ring, designed for 22 mm push-button stations with a mounting hole of 22.5 mm. It is rated IP66 and Type 4/13 for enclosure compatibility, making it suitable for washdown and harsh industrial environments. Key specs include a 10 A thermal current rating for the contact block, a mechanical life of up to 300,000 cycles, and a contact-block durability of up to 10,000,000 cycles. The device is non-illuminated, with the twist-to-release E-stop function and a standard pack quantity of 1. This head is well-suited for safety interlocks and emergency-stop circuits on control panels in manufacturing or process lines where a clearly visible red 40 mm mushroom head and reliable twist-release action are required.
