Claims

[Scope of utility model registration request]

A photoelectric switch in which an optical block and a circuit board are integrated into a case, and the optical block includes a cap located at the front of the case and a cap located at the rear of the cap. The optical holder is provided with an optical holder engaged with the cap so as to be coaxial with the cap, and the cap is a cylindrical body with an open rear end. The optical holder is a cylindrical body with a photoelectric element fitted therein, and a mounting leg protrudes from the rear thereof, and the circuit board is a lens.
A photoelectric switch characterized in that a front end portion is attached to the mounting leg and the photoelectric element is electrically connected to the mounting leg.
