The Miller Sensing Edge MT22 is a vital component for ensuring safety and efficiency in various applications such as rolling fire doors, rolling steel doors, and material handling systems. This durable sensing edge is available in three standard models, with the MT22 size measuring 2” in width and 2” in height.

Crafted with a flexible design, the MT22 sensing edge can easily conform to irregularities in the floor, providing a secure and reliable solution for door operation control. The vinyl jacket covering the sensing edge ensures longevity and protection against wear and tear.

Key features of the MT22 include its compatibility with 2+ inch thick surfaces, customizable options for color, length, and outlet location, and 5-6 inch end flaps for a secure seal. The sensing edge is also equipped with patented Alumaglas™ technology for superior performance.

Manufactured in the US, the Miller Sensing Edge MT22 meets UL 325 standards and comes with a 1-year warranty for added peace of mind. With extended color options, including a chemical-resistant yellow XR5 jacket, the MT22 is a versatile and practical choice for your safety needs.

For a seamless ordering experience, refer to the complete ordering guide provided by the manufacturer to ensure the MT22 is tailored to your specific requirements. Invest in the Miller Sensing Edge MT22 for a robust and reliable solution to enhance safety measures in various door operations.

The MT sensing edge product line consists of three standard models: MT21  (2”W x 1”H), MT22 (2”W x 2”H), and MT33 (3”W x 3”H). When touched lightly, the sensing edge will send an immediate signal to operator controls to stop and/or reverse door operation. The MT edge switch is covered in a durable vinyl jacket. The top tab inserts between the double-L angle bottoms bars on a rolling door. These sensing edges are flexible and can conform to irregularities in the floor.
