| description | The utility model discloses a photoelectric sensor. The device comprises a light emitting module and a light receiving module, the signal light can be reflected to the light receiving module through areflecting plate arranged on one side of the light emitting module; characterized in that it is characterized in that it comprises, a plurality of groups of diaphragms are arranged between the spherical lens of the light receiving module and the light receiving tube; the center of the diaphragm is provided with a light hole located in a signal light focusing path. The periphery of the diaphragm is fixed to the surface of the inner wall of the shell of the light receiving module, stray light can be prevented from irradiating the receiving tube at a short distance by arranging the accurate receiving diaphragm, the detection distance is increased, optical signal concentration and low return difference are achieved, and misoperation generated when a high diffuse reflection object is detectedat the near end of a produ |
