As our society continues to evolve, an abundance of new products emerge in our daily lives. The introduction of industrial folding doors brings convenience to our lives and also adds a touch of color.

Industrial doors are the main product we are introducing to you today. The principle of voltage division detection for industrial door potentiometers is as follows: The total travel distance of the door, S, is linearly correlated with the total resistance, R, of the rotating potentiometer. The reducer's减速轴is connected to the rotating head of the potentiometer. The potentiometer's terminals are connected to the power supply. As the door operates, the rotating head of the potentiometer rotates with the reducer shaft. The resistance between the potentiometer's tap terminal and ground changes, and so does the voltage. By detecting the voltage at the potentiometer's tap terminal through an AD converter, the position information of the door can be determined, which is the principle of voltage division detection.
