Infrared photo beam sensor and safety edge protection device for PVC high speed door

PVC high speed rolling shutter door has the characteristics of heat preservation, collision prevention, insect prevention, windproof, dustproof, sound insulation and so on. It can realize fast operation, open and close the door. Therefore, it is widely used in production space with strict environmental requirements, such as food, electronic workshop, printing and packaging, chemical industry, pharmaceutical, dust-free workshop, logistics and storage and other places. Some users will ask whether the fast rolling shutter door can ensure the safety of people or objects? There are two main safety protection methods for fast rolling shutter doors: photoelectric protection device photo beam sensor and airbag. 

1. Safety adge (airbag). 

It is composed of a receiving end device and a transmitting end device. The transmitting end device controls the air pressure switch and sends the circuit. The sealing at the bottom of the air bag is installed to trigger the air pressure switch under the door body and curtain. Remove the object rear door will automatically drop, this function is effective in manual automatic, to ensure the safety of people and cars. Wireless airbag device has the advantages of high reliability, easy installation and easy maintenance.   

2. Photo beam sensor 

When the fast rolling shutter door uses reflective photoelectric switch, the induction range is 0-5 meters (shooting type is suitable for more than 5 meters range position) installed on both sides of the door post, the height is 30 to 40 centimeters. When the door body runs automatic descent, someone or an object blocks the sensor, the door will stop descending immediately and automatically rise to the top. When the object is removed, the door automatically descends to the bottom. Both automatic and manual.
