Pressure sensitive sensing edges or edge sensors are used as signaling and initiating devices on machinery or as safety devices where pinch points exist on automatic machinery doors. Edge sensors in signaling or initiating applications are typically actuated by an operator's deliberate hand or foot motion. Edge sensors are used in safety applications to stop or reverse automatic doors or moving machinery. These sensing edges offer cushioning to absorb over travel that occurs between the stop command and the actual end of motion. Sensing edge systems consist of the edge itself and an edge controller to interface with the equipment controls.
