Claims

[Scope of utility model registration request]

On one side of the case body formed in a U-shape, a communication groove and a cavity groove, in which light emitting/receiving elements, wiring, electric circuit boards, etc. are housed and resin molded, are arranged in series, and are opposed at both protrusions of the case body. A fitting hole for attaching the emitter/receiver element and this small hole are drilled in the inner wall of the tip of the two holes so that the optical axis coincides with the through hole drilled in the outer wall of the tip of both holes, and the hole diameter is selected appropriately. A groove-type photoelectric switch characterized in that the front side of the small hole is airtightly covered with a transparent protective plate made of hard glass or the like.
