Claims

[Scope of utility model registration request]

In a photoelectric switch in which a light-emitting element and a light-receiving element are arranged facing each other and each element is provided with a window or a window fitted with a lens to limit the optical path, at least the shape of the light-emitting part and the light-receiving part of the pixel element or the shape of the lens is A photoelectric switch characterized by one being narrow.
