What is an Automatic Sliding Door and How Does It Work?

An automatic sliding door is a type of door that uses a sensor to detect motion for opening or closing. These doors are commonly used in areas with high pedestrian traffic, such as shopping malls, hospitals, hotels, and airports. The advantages of automatic sliding doors include energy efficiency, hygiene, security, and convenience.

The working principle of automatic sliding doors is as follows: A sensor located above or beside the door emits infrared beams to scan the area in front of the door. When a person or object enters this area, the sensor detects it and generates an electric signal. This signal activates a motor, which opens or closes the door. When the area in front of the door is clear, the sensor cuts off the signal, and the motor closes the door.
