特徴とする透過形光電スイツチ。 The light emitted from the light emitter is received by a light receiver placed opposite to the light emitter, and the presence or absence of the detected object is detected by blocking the light by a detected object that crosses the optical axis of the light emitted from the light emitter. A transmission-type photoelectric switch for detecting a light source, the light-emitting device is equipped with a light-emitting element having a vertically elongated slit on the front surface of the light-emitting device case, and a lens placed in front of the light-emitting element. .
