置。 Between the light emitting optical system and the light receiving optical system, which consist of a light emitting element and a light receiving element attached to one holder, and a lens block that is attached to a case and integrates a light emitting lens and a light receiving lens. In the infrared light shielding device for a photoelectric switch in which an inserted light shielding plate blocks infrared light leaking between the two optical systems, the light shielding plate is integrated with a rubber gasket between the case and the lens lock or with the holder. An infrared light shielding device for a photoelectric switch, characterized in that a portion through which leaked infrared light passes is particularly thick.
