The three-inch wide MU33 sensing edge was specially developed for aircraft hangar doors and material handling systems. MU33 is manufactured to your exact specifications for color, length, and outlet location. Install by wrapping the top tabs around the leading edge of a three-inch thick door or surface to minimize risk of injury and damage to aircraft and other equipment. The flexible jacket that covers the internal edge switch allows MU33 to conform to slight irregularities in the floor or other surfaces. When touched lightly, the sensing edge will send an immediate signal to operator controls to stop and/or reverse door operation.
