Abstract
An adjustable height sensing edge for a door to protect persons, equipment and the door from impact damage from closing movement of the door by actuating a stopping device upon detecting an object in contact with the sensing edge, the device stopping the closing movement of the door. The adjustable-height sensing edge comprises a base member having opposing first and second surfaces. The first surface of the base member is adapted for attachment to the door. A first sensorless compressible spacer member having opposing first and second sides is provided. The first side of the sensorless spacer member is attached to the base member. A force sensor is provided for sensing the object in contact with the sensing edge and activating the stopping device. The force sensor has opposing first and second sides, with the first side of the force sensor being connected to the second surface of the base member.
