ツチ。[Claims for Utility Model Registration] It is placed inside a machine that handles photosensitive materials, and detects the presence or absence of an object based on whether or not infrared rays pass through the detection space and reach the light receiving element, and this is detected electrically. In addition to outputting with ON and OFF signals,
An operation indicator light housed in the display window of a case equipped with a light-receiving element lights up to indicate the presence or absence of object detection. A photoelectric switch characterized by a removable sticker that converts into visible light and emits light.
