Abstract
A door system includes a sensor device for monitoring a vertical door edge. The sensor device has a transmitter that generates a light beam that runs along the vertical door edge, and a receiver to receive the light emitted by the transmitter. Further, an element of the sensor device is mounted in a region of a base of the door, with the sensor element being either in or on the base in front of the vertical door edge.
