In the intelligent manufacturing, food processing, biomedical, semiconductor clean room, and other environments, cleanliness and pass-through high-efficiency requirements of the place, the traditional button-type door opening method has long been unable to meet the demand for “zero contact” operation. At this time, a combination of high response, no contact, and safety equipment – a light curtain sensor contactless fast door- is becoming the mainstream choice.
What is a light curtain sensor contactless speedy door?

Light curtain sensor contactless fast door means that the door body is equipped with a high-precision infrared light curtain sensing device, which can detect the movement signal of personnel, forklift trucks, or other objects in real time and automatically start the door opening action, without physical contact with any button, remote control or pull rope. It realizes precise identification through infrared raster scanning, which improves the passage efficiency while safeguarding health and safety.
The core advantage of light curtain induction fast door
Truly realize “contactless operation”.
In clean environments such as food workshops and medical GMP workshops, it is easy to bring in contaminants by touching the door with the hand. The light curtain induction technology completely avoids the physical contact between humans and the door, and guarantees the safety of the production environment.
Fast response, improve the efficiency of passage
High-frequency operation area is most afraid of slow response of the door body. Light curtain induction has millisecond response speed, when people or forklifts enter the induction area immediately start, significantly reducing the waiting time.
Typical application scenarios
Light curtain induction contactless speed door is suitable for the following typical scenes:
Clean room workshop passage: preventing contamination, guaranteeing aseptic environment
Cold chain logistics area separation: automatic rapid opening, reduce temperature loss
High-frequency operation storage entrances and exits: efficient dust prevention, energy saving and consumption reduction.
AGV robot passageway: accurately recognizing automatic equipment, avoiding misopening and misclosing.
Configuration Upgrade Recommendations
To further enhance the performance and intelligence level of the door, it is recommended to use it in combination with the following systems:
Bi-directional light curtain sensing system: for bi-directional access areas
Anti-collision self-repairing curtain: even after being hit by a forklift truck, it can automatically return to the track.
Linked access control and identification systems: for greater control and security in the use of the door.
Conclusion
The light curtain induction contactless speed door not only solves the contact pain point during high-frequency passage. But also realizes a clean, safe, and efficient integrated door control solution through intelligent control and safety configuration. It is undoubtedly the first choice for future development in industries that emphasize production safety and sterility standards.
