automatic sliding door mechanism information

The use of small size and low power DC brushless motor ( the long life and low noise compare with brush motor ), with deceleration of the transmission efficiency, low noise, high-speed gearbox system, and then drive the belt. The internal of the motor has security circuit device, even if the frequent opening and closing, but also to achieve long-term trouble-free operation. 
1. Using DC brushless DC24V65W motor.
2. Starting torque is powerful.
3. With the optical scale of the measurement function.
4. Has a stable rotation torque and speed.
5. Long service life, low operating noise.

Wisdom miniature computer controller
Automatic door mind is totally microcomputer optimized. Internal signal loops adopt no contact control mode, even after longtime working, opening and closing movement is still accurate. Door leaf position setting and adjustment, slide distance setting and adjustment, door leaf opening and closing speed setting and adjustment is accurately controlled by sliding door controller.
The door open immediately if detected an obstacle.
When the doors is closing, if it meets a pedestrian or obstacle, the door leaf will reverse automatically, the door will open immediately, it prevents pinching events and door damaged ,also improves the automatic door working life.
If the electricity is failed, the door will stop moving. However, there is very little resistance, door leaf can easily be opened by hand.
Good modular design offers very easy installation. Only need to fit all components into the guide rail and connect each part well, it can work after activating the power supply.


The automatic slider can be intergrated with access control systems. Like magnetic door lock, exit push button, microwave sensor, infrared sensor, remote control, etc.
