Abstract

PURPOSE: To make the detection start position and the end position fixed to improve the detection position precision by providing a hood, which is placed in the front side of a projector element and a light receiving element and has a slender aperture part with parallel long side parts, in the photoelectric switch main body.
CONSTITUTION: Hood 5 which has a slender front aperture part 8 with parallel long side parts at the tip is provided on photoelectric switch main body 1, and the light from projector element 2 is irradiated from this aperture part 8 to the external. The light from this aperture part 8 has long side parts 11a and 11b long and parallel with each other and becomes narrow beam 11 having the section of an approximately long rectangular form. In case that this beam 11 is irradiated to detected object 13, which is transferred by the transfer path, to detect it, the detection start position and the end position are not shifted and are fixed even for transfer positional shift of detected object 13. As the result, the output signal of light receiving element 3 becomes waveform d, so that operation control of succeeding-stage units can be performed stably.
