SC113X 4mm Dip Type One Pole Position Detecting Car Window Hall IC Sensor

Application of Hall IC sensor in car window

Modern automobile windows use automatic electronic control methods. For the window control system, safety is a necessary condition. When the window moves up and down, the force generated is between 200 N and 300 N, and the instantaneous (within 10 ms) force can reach 100 N. So when the hands or other body parts of the arms are placed inside, it is easy to cause pinch injuries. In order to prevent unnecessary damage to the human body caused by windows and related requirements, the electric window control system in the car must strengthen safety protection measures. Among them, the Hall IC sensor plays an important role in the anti-pinch of car windows.

In the power windows of automobiles, the electric power is mainly used for lifting and lowering. In addition, it is also equipped with a corresponding electronic control system, which is mainly responsible for the detection and control of the rotation direction and working status of the motor. Therefore, the rising/falling of the window is completed, and a series of operations are started/stopped. In the window control system, the Hall IC sensor mainly plays the role of circuit current change and detection of motor movement. During the window lifting process, the Hall sensor can accurately measure the number of cycles of motor rotation to determine the current travel position of the window, so that when the window is lifted to a certain position, the power supply can be turned off and the motor can stop working in time . When a car window is stuck due to mechanical failure or human body parts, not only will the motor be burned out due to the excessive rotor current generated when the motor stops, but also the body parts stuck in the car window will be damaged. Hall sensors are used to detect changes in the magnetic field caused by the current in the motor circuit. When the current caused by the motor shutdown exceeds the safety threshold, the window control system can adjust the motor's reverse rotation in time to avoid clamping accidents or motor damage caused by it.
