Elevator use encoder encoder 

I. Overview This device is suitable for all movable car-bottom elevators that require overload signals and escalators that require energy-saving operation. It can also be used for mechanical limit or proximity switches. This device has a very high cost performance. It uses Hall sensors to achieve non-contact induction work. In this way, the system does not directly bear the elevator load, so it has the advantages of long working life, good stability, and convenient installation and debugging. The defect that mechanical overload switch is easily damaged. 2. Main features 1. Non-contact induction working mode, no mechanical movement of itself, directly installed at the original overload switch of the elevator, without changing the elevator car structure. 2. The use of ultra-high and strong induction magnet to maximize the system's anti-interference ability. 3. High positioning accuracy, small size, convenient installation and debugging, simple structure and low price.
