項記載の光電スイツチ。[Claims for Utility Model Registration] (1) In a photoelectric switch having a light emitting/receiving section and detecting an object based on an optical signal, the photoelectric switch is provided in front of at least one of the light emitting/receiving elements of the light emitting/receiving section, a light shielding plate that blocks the light emitted from the light projecting section or the light given to the light receiving section; and a light amount adjusting means that adjusts the amount of light emitted from the light projecting element or given to the light receiving element by displacement of the light blocking plate. A photoelectric switch comprising: (2) The light-shielding plate has a threaded groove formed therein, and the light amount adjustment means includes a sensitivity adjustment bolt that engages with the threaded groove, and the light-shielding plate is moved by the rotation of the bolt. A photoelectric switch according to claim (1) of the utility model registration, characterized in that: (3) The utility model characterized in that the light amount adjusting means is a member formed integrally with the light shielding plate, and the light amount is adjusted by rotating the light shielding plate by rotating the light amount adjusting means. Scope of Registration Claim No. (1)
Photoelectric switch described in section.
