Vorrichtung zum beruehrungsfreien Erfassen von Gegenstaenden

The device has at least two detection elements (81) positioned transverse to the direction of movement (9) of the device, for detecting transmitted electromagnetic radiation reflected from an object (13). The detection elements are coupled to an evaluation circuit using the reflected radiation intensity for determining the spacing of the object from the detection elements. A recognition signal is provided by the evaluation circuit when the intensity variations and the distance variations lie within defined plausibility limits. USE - For automatic mast detection for electric locomotive. ADVANTAGE - Reliable object detection under all lighting conditions.
