ABSTRACT:
A conductive cord connection system for a movable sliding door with an electrical sensing edge provides a simple and inexpensive cord arrangement. The conductive cord extends, with the door closed, directly from the sensing edge through a door bracket and a wall bracket to a motor operator. With the wall bracket, which frictionally holds the cord, positioned adjacent to the door and spaced from the door bracket, a distance that is one half of the distance of total door travel, the traveling cord portion is substantially straight in the full open and closed positions of the door. When the door is opening or closing, a loop formed in the traveling cord portion does not exceed in length 25 percent of the full door travel.
