The Miller Sensing Edge MU22 is a reliable and versatile product designed to enhance safety and efficiency in various applications. With three standard models available, including the MU22 (2”W x 2”H), this sensing edge ensures prompt signaling to operator controls for stopping or reversing door operation with just a light touch.

Crafted with a durable vinyl jacket, the MU sensing edge is built to withstand the rigors of commercial environments and can easily conform to floor irregularities. The flexible design allows for seamless installation on both vertical and horizontal surfaces, making it ideal for use in commercial sectional doors, aircraft hangar doors, and material handling systems.

Featuring optimum dimensions for 2-3 inch thick surfaces, the Miller Sensing Edge MU22 can be custom manufactured to suit specific requirements regarding color, length, and outlet location. The addition of 5-6 inch end flaps ensures a secure seal, with the option to trim for a custom fit. The MU22 is also available in extended color options, including a yellow chemical-resistant XR5 jacket for added durability.

The MU22 boasts a sealed assembly that is impervious to dust and debris, while its patented Alumaglas™ technology offers superior performance, especially for electric applications. Recognized as a UL 325 Component, this product comes with a 1-year warranty and is proudly made in the USA.

For a comprehensive ordering guide and detailed specifications, please refer to the provided links and guidelines. The Miller Sensing Edge MU22 is a reliable solution that prioritizes safety, adaptability, and quality, making it an essential addition to any industrial or commercial setting.

The MU sensing edge product line consists of three standard models: MU21  (2”W x 1”H), MU22 (2”W x 2”H), and MU33 (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 MU edge switch is covered in durable vinyl jacket, and its flexibility allows it to conform to floor irregularities. The top tabs wrap around the leading edge of a sectional door.
