The Miller Edge MU33 sensing edge is a premium safety solution for sectional doors, hangar doors and material‑handling systems. Designed to activate with even a light touch, this 3‑in‑by‑3‑in profile sends an immediate stop or reverse signal to the operator controls, helping prevent accidents and damage. Its robust vinyl jacket resists harsh conditions and the flexible construction conforms to floor irregularities for a dependable seal. Thanks to patented Alumaglas™ technology and UL 325 recognition, the MU33 offers superior electrical performance and meets modern safety standards. The MU33 is ideal for commercial and industrial settings, but it’s also compatible with residential gates and garage doors, delivering reliable entrapment protection in diverse applications.
Beyond reliability, the MU33 focuses on adaptability. It can be manufactured to your specifications—choose the exact length, color (including high‑visibility striped and chemical‑resistant XR5 jackets) and wire/monitoring type to meet your system requirements. The edge mounts vertically or horizontally and features 5‑ to 6‑inch end flaps that create a complete seal and can be trimmed for a perfect fit. A sealed assembly keeps out dust and debris, ensuring long‑term performance, while the durable construction is backed by a one‑year warranty and proudly made in the USA. With its combination of rapid response, customizable options and rugged build, the Miller Edge MU33 enhances the safety and efficiency of automated door systems.
