High-speed roller shutter door has the functions of heat preservation, moisturizing, cold preservation, insect proof, windproof, dust-proof, soundproofing, fireproof, anti-odor, lighting, and quick opening and is widely used as industrial plant doors, workshop access doors, warehouse doors, anti-moist doors, dust doors, anti-air convection doors, etc.  

The fast rolling door has unique performance such as  high stability, superior pass-ability, intelligent handling, fast opening and closing, and low noise. It is divided into radar induction control, geomagnetic induction control, photoelectric induction control, and rope sensing control. Its switching speed is 20 times that of ordinary steel rolling doors, which can greatly increase the production efficiency of the factory.

Following is a introduction of Sensor function at high-speed roller shutter door

1. Radar induction control: The microwave emission is used to sense the moving object. When the object enters the emitting area, the microprocessor will immediately send a signal, and the door will automatically rise to the top. According to the preset delay time, the door will automatically drop. The sensitivity and sensing distance of the sensing are adjustable, and this function is automatically effective.

2. Geomagnetic detection control: The presence of the vehicle is detected by the change in inductance that occurs in the rectangular coil buried under the ground. When the vehicle passes through the sensing area, it will immediately send a signal, and the door will automatically rise to the top. After the car leaves the sensing area, it will automatically drop according to the preset delay time, and its sensing sensitivity can be adjusted.

3. Remote control: The effective distance is 30 meters. When the vehicle is about 5 meters away from the door, the driver will manually send a signal to let the door open. After passing, press the transmitter to descend, or use the automatic automatic delay to drop the position. Different doors can be controlled by using the 1-12 button to control them.

4. Manual drawstring control: The working environment has a narrow space and frequent access. When the radar or geomagnetic signal is mishandled, the pull rope is used to control the door to open and close.

5. Photoelectric induction control: Retro-Reflective type photoelectric sensor with effective distance 20m and opposed type photoelectric sensor with different detection distance for selecting: 10m, 25m and 50m etc. Photoelectric sensor signal is divided into normally open type and normally closed type, used according to door requirements, effective distance of material inlet and outlet.
