ABSTRACT:
A sensing edge for causing a closing door to open by actuating a device upon force being applied to the sensing edge. The sensing edge includes an elongate outer sheath compressible upon application of external pressure. A sensor is positioned within the elongate outer sheath for sensing the application of force to the sheath. Upon force being applied to the sheath, the sensor actuates a device for controlling the door. The sheath includes an aperture extending through one of the end surfaces. Electrical conductors that are in electrical communication with the sensor extend through the aperture, outwardly from the one end surface beyond the side surface of the door and into the internal area of a track to which the door is mounted. The sensor includes a flexible hood which extends outwardly from one end surface of the sheath and into the track area. The hood has second and third apertures extending therethrough. An installer of the sensing edge can place the conductors through either one of the second and third apertures and therefore allow for the electrical conductors to be positioned proximate either the first or second side surface of the door such that the sensing edge is bilateral.
