| 摘要 |
A sensor device is proposed for monitoring a mobile moving element, guided in a guide, with respect to undesired collisions of the moving element with an object which is located in a monitoring range, having at least two sensors for sensing the object, wherein the sensors comprise a transmitter and a receiver for emitting and receiving electromagnetic rays, wherein the sensors are arranged one next to the other in such a way that they can be mounted parallel to the guide, and the sensors are also oriented in such a way that the rays emitted by them penetrate the monitoring range. In order to enable improved obstacle recognition, the sensors are embodied as distance sensors for determining the distance from the object. In addition, a safety device, a door and a method for monitoring the movement are proposed. |
