。[Scope of Claim for Utility Model Registration] (1) A cylindrical structure that connects one end of the light emitting optical fiber 3 and the light receiving optical fiber 4 to the photoelectric switch body 1, and forms a detection surface on the other end of these optical fibers. A detection head 5 is provided, and a connecting portion 7 having an outer diameter smaller than that of the detection head is integrally formed on the side of the photoelectric switch main body 1 of the detection head, and a connecting portion 7 having an outer diameter smaller than the outer diameter of the detection head is provided. Both the optical fibers 3 and 4 are covered with a protection tube made of plastic material between the detection head 5 and the detection head 5 of this protection tube.
An optical fiber type photoelectric switch whose side end is connected to the connecting part 7. (2) The optical fiber type photoelectric switch according to claim 1, wherein a protrusion 9 is provided on the outer periphery of the connecting portion 7 to prevent the protective tube 11 from coming off.
