Abstract
The invention relates to a proximity switch for the detection of objects, comprising a sleeve-type housing, comprising a transducer unit disposed at a measuring end of said sleeve-type housing, the transducer unit comprising a transducer receptacle and a transducer element disposed therein for detecting a physical measurand, comprising a connecting piece disposed at a connecting end of said sleeve-type housing, comprising an electronic assembly disposed on a printed circuit board accommodated in said sleeve-type housing and having a control and evaluation unit adapted to control said transducer element, to evaluate signals measured by said transducer element and to emit switching signals to an environment, wherein variously colored light-emitting diodes are disposed on said printed circuit board at the measuring end and at the connecting end for indicating operational and/or switching states, wherein said transducer receptacle exhibits a transparent region disposed around a housing axis and/or a transparent region at an end face. The proximity switch is characterized in that said connecting piece has a peripheral transparent region, that said transparent regions at said measuring end and at said connecting end are optically homogeneous, that said transparent regions are each capable of being monochromatically illuminated by said light-emitting diodes and that said control and evaluation unit is adapted to control the respective variously colored light-emitting diodes for indicating different operational and/or switching states.
