<P>PROBLEM TO BE SOLVED: To provide a sensor device 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. <P>SOLUTION: A sensor device 1 has at least two sensors 5 for sensing an object 4, in which the sensors comprise a transmitter and a receiver for emitting and receiving electromagnetic rays 6, in which the sensors are arranged one next to the other in such a way that they can be mounted parallel to a guide 3a, and the sensors are also oriented in such a way that the electromagnetic rays 6 emitted by them penetrate a monitoring range. In order to enable improved recognition of an obstacle 4, the sensors are embodied as distance sensors for determining the distance from the object 4. In addition, a safety device, a door 2 and a method for monitoring the movement are also proposed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
