Optoelectronic sensor arrangement for contact or proximity switch has transparent surface in light path that reflects light to photosensitive element as receiver if touched or approached
Optoelectronic sensor arrangement for contact or proximity switch has transparent surface in light path that reflects light to photosensitive element as receiver if touched or approached
The arrangement has a light beam radiator in a transparent housing, a photosensitive element receiver outside the light path from the radiator and a transparent surface in the light path that reflects light to the receiver if touched or approached. The transparent surface is formed by the housing, which acts as a light conductor and the photosensitive element is arranged immediately close to and outside the housing in the radiation direction. The arrangement has a light beam radiator (1) in a transparent housing (2), a photosensitive element (4) as a receiver arranged outside the light path (3) from the radiator and a transparent surface in the light path that reflects the light to the receiver if touched or approached. The transparent surface is formed by the transparent housing, which acts as a light conductor and the photosensitive element is arranged immediately close to and outside the housing in the radiation direction. AN Independent claim is also included for the following: an illuminated light sensitive switch.
