Elevator permanent magnet photoelectric switch leveling magnetic sensor HDYG-1A

Function:
Position detection: used to accurately detect the position of the elevator car. In the elevator shaft, permanent magnetic sensors are installed at certain intervals. When the elevator car runs near the permanent magnetic sensor, the sensor will sense the permanent magnet on the car, thereby sending a signal to the elevator control system to inform the control system of the specific position of the elevator car, so as to achieve functions such as accurate floor leveling and parking.
Speed ​​monitoring: The running speed of the elevator can be monitored in conjunction with other equipment. By sensing the frequency and other information of the permanent magnet passing through, the real-time speed of the elevator is calculated. Once the speed exceeds the normal range, the sensor will transmit the signal to the control system, so that the elevator can take corresponding safety measures, such as braking, to ensure the safety of the elevator operation.
Safety protection: It is an important part of the elevator safety control system. For example, in the case of elevator overspeed, door lock abnormality, etc., the permanent magnetic sensor can detect the relevant state changes in time, and transmit the signal to the safety brake device, triggering the braking action, stopping the elevator and preventing accidents. At the same time, in the elevator door system, it can also be used to detect the opening and closing state and position of the door to ensure the normal operation and safe closure of the door.
