In the event of a fire, it is necessary to spray water to fight the fire. When the elevator leveling limit photoelectric switch is sprayed with water, no water can enter its interior to ensure that it can work normally after being sprayed with water. General photoelectric switch outlet holes and potentiometer knobs are not sealed or the sealing effect is not good, and the light-transmitting window adopts an independent transparent light-transmitting window that needs to be installed in conjunction with the housing. The transparent light-transmitting window is easy to allow external interference light to enter and interfere with the normal operation of the switch. The installation of the window and the shell takes man-hours and increases the cost of the switch. If the cooperation is not good, the protection level is difficult to reach IP66 or above.
