Crafted with precision, the MU21 sensing edge features a compact size of 2”W x 1”H, making it ideal for 2-3 inch thick surfaces. The edges are custom-manufactured to meet user specifications, offering flexibility in color, length, and outlet location. Whether mounted vertically or horizontally, the MU sensing edge delivers exceptional performance.
Built to withstand rigorous conditions, the sensing edge switch is encased in a durable vinyl jacket that ensures longevity and resilience. Its flexible design allows it to conform to floor irregularities, while the top tabs securely wrap around the leading edge of sectional doors for seamless integration.
Key features of the Miller Sensing Edge MU21 include extended color options, such as the yellow chemical-resistant XR5 jacket, and patented Alumaglas™ technology for superior electric performance. Additionally, the sealed assembly is impervious to dust and debris, providing uninterrupted operation.
For added peace of mind, the MU21 comes with a 1-year warranty and is proudly made in the USA. Recognized as a UL 325 Component, this sensing edge is a trusted safety solution for modern operators.
Enhance safety and efficiency with the Miller Sensing Edge MU21, a reliable choice for a wide range of applications. Upgrade your security measures with this premium product designed to meet the highest standards of quality and performance.
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.
