ZR-335-11Z-M20 Limit Switch For Elevator

The limit switch for elevator is an important control device to ensure the safety of the elevator, which is used to monitor the moving status and position of the elevator during operation, and prevent the elevator from accidental injury or accident due to overload, speeding or failure. Its main role includes the following aspects:

1. Control the elevator track limit: The elevator limit switch controls the elevator within the safe range by monitoring the position and movement speed of the elevator in the process of going up and down, avoiding the elevator from exceeding or deviating from the track limit during operation, and protecting the elevator infrastructure and the personal safety of passengers.

2. Acceleration and speed control: The elevator limit switch can also control the movement of the elevator according to the specified acceleration and speed limit to ensure the smooth operation and safe operation of the elevator.

3. Monitoring elevator load weight: Elevator load weight is an important indicator of elevator operation. The elevator limit switch can monitor the load weight of the elevator in real time to avoid accidents and damage caused by elevator overload.

The realization principle of limit switch for elevator:

1. Electronic sensor control: Electronic sensors can detect the physical parameters such as the position, speed and load of the elevator, and input the control signal into the control system to realize the limitation and protection of the elevator.

2. Mechanical control system: The mechanical control system measures and controls the physical parameters such as the upstream and downstream range, speed and load of the elevator by setting up sensors, limiter and other mechanical devices. When the elevator is running, once the elevator is found to deviate from the limit range or overload, the mechanical control system will immediately stop the elevator operation and issue an alarm signal.
