Electric Actuator Exists on the Sliding Terminal

Since there is a sliding terminal in the electric actuator, it is easily wear, the life is short, and there is a fixed dead zone, and it is difficult to install freely, it is difficult to implement the cover debugging.
In addition, the single-loop potentiometer and the bearing gear are used in a multi-rotating electric actuator, resulting in a large-ener-worn of the electric actuator to solve the easy-to-worn loss of the use potentiometer, there is a short life, and there is a fixed dead zone. It cannot be installed, the return is large. The defects have detected a valve bit in a non-contact Hall sensor. This magnetic sensor has the characteristics of non-wear, high precision, no fixed dead zone, small back, and achieving free cover debugging.
