Abstract
A sliding door system employs an electric power link. The electric link includes a ribbon conductor which is enclosed in a protective chain-like guard to provide electrical communication between the sliding door and the door header. Electrical modules such as electromagnetic locks, switches and sensors are mounted directly on the sliding door. Safety sensors are mounted at the leading and trailing edges of the sliding door panels to sense whether an obstacle or traffic has cleared.
