ABSTRACT:
A sensing edge for actuating a device to cause a closing door to stop closing upon a force being applied to the sensing edge is provided. The door has a leading edge surface, a first lateral surface, and a second lateral side surface with the first and second lateral side surfaces being oppositely disposed. The sensing edge comprises an elongate sheath positioned adjacent to the leading edge surface of the door and compressible upon application of an external force. The sheath forms a cavity. The sheath has a front side and a back side and first and second oppositely disposed end openings. The front side and back side of the sheath have respective front side and back side apertures extending therethrough. A sensor responsive to an external force applied to the sheath substantially between the first and second openings is positioned within the cavity. A plug is also positioned within the cavity proximate to the first end opening of the sheath. The plug has a first surface facing the cavity, second and third surfaces facing respectively the front and back sides of the sheath and a fourth surface facing the first end opening. The plug has a channel structure extending from the first surface through the plug to the second and third surfaces. At least one electrical conductor is in electrical communication with the sensor for connection with a circuit for controlling the actuation of the door when the sensor detects the application of force to the sheath. The conductor extends through the channel structure from the first surface to one of the second and third surfaces.
