ことを特徴とする光電スイツチ。 It is equipped with an optical block main body and a case that houses the main body, and the block main body includes a light projection lens that focuses the light rays from the light emitting element and irradiates them in a certain direction, and a light projection lens that collects the light rays reflected by the object to be detected. A light-receiving lens that focuses a portion of the light and makes it incident on the position detection element is incorporated, and the integration is performed by fitting a protrusion provided on the outer periphery of each lens into a groove provided in the block main body, and An optical filter is disposed on the front surface of the block body through which the light beam passes, and the block body is housed in the case and filled with resin so that the optical filter is located in an opening provided in the case. In the photoelectric switch, the optical filter is provided with a portion that fits into the groove so as to press down both lenses, thereby sealing the inside of the optical block body from the outside. A photoelectric switch.
