Small thin proximity sensor for industrial robot hand

The utility model discloses a small thin proximity sensor for an industrial robot hand. Proximity sensor comprising a proximity sensor body, a sensor protection device is further included, the bottomof the sensor protection device is sleeved with the top end of the proximity sensor body; the sensor protection device comprises a top cover. The bottom of the top cover is connected with the top endof the proximity sensor body in a sleeved mode, the outer wall, close to the bottom, of the top cover is in threaded connection with a limiting screw, the end of the limiting screw penetrates into thetop cover and abuts against the outer wall of the proximity sensor body, rotating grooves are formed in the top face and the side face of the top cover, and rotating blocks are rotatably connected into the rotating grooves. According to the utility model, through the cooperation of the above structures, the rotating block can realize the switching between two states, i.e., the switching between the vertical state and the t
