Abstract
A sensor (10) is provided for detecting an object (20) in a monitored zone (18), having at least one sensor element (36) for detecting a sensor signal; having a switch output (30) for outputting a binary object determination signal; and having an evaluation unit (28) that is configured to generate the object determination signal from the sensor signal in dependence on the detected object (20) and to determine, in a teaching phase, a switching point that determines the association between the sensor signal and the object determination signal. The evaluation unit (28) is further configured to detect a respective sensor signal for a plurality of detection situations in the teaching phase, with the associated object determination signal being predefined for the respective detection situation and with the switching point being derived therefrom.
