Automatic sliding doors have become a standard feature in modern commercial buildings, hospitals, hotels, and public facilities due to their convenience, accessibility, and hygienic hands-free operation. But have you ever wondered what happens behind the scenes when the door opens as you approach?
As a leading automatic door opening system supplier, Teeky International explains the working principles of automatic sliding door openers—from the key components involved to how they function together in real time.
Basic Overview
An automatic sliding door opener is a system that automates the movement of a door panel, allowing it to open and close without manual effort. The process is typically triggered by motion sensors and powered by an electric motor, all managed by a central control unit. The system is designed to respond instantly and safely, ensuring smooth operation for all users.
Key Components of an Automatic Sliding Door Opener
Understanding how the system works begins with identifying its core components:
1. Motion Sensors
Motion or presence sensors (usually infrared or microwave) detect when someone approaches the door. Once triggered, they send a signal to the control unit to initiate opening.
2. Control Unit
The control unit is the brain of the system. It receives input from sensors and determines how the door should respond. It also manages settings such as door speed, hold-open time, and obstacle detection.
3. Drive Motor and Gearbox
The motor converts electrical energy into mechanical motion to slide the door open or closed. A gearbox reduces the motor’s speed while increasing torque, ensuring controlled, powerful movement.
4. Track and Roller Assembly
The door panel is mounted on a track and guided by rollers that allow it to slide smoothly. The motor is usually connected to a belt or chain drive that pulls the panel back and forth.
5. Safety Sensors
Additional sensors near the bottom of the door detect obstacles or people standing in the doorway. If something is in the path, the door will stop or reverse to prevent injury.
6. Manual Override and Emergency Features
In case of power failure, systems often include a manual release function, allowing users to operate the door manually. In emergency exits, a break-out system may allow the door to swing open.
How the System Works — Step by Step
Step 1: Detection
A motion or presence sensor detects a person approaching the door.
Step 2: Signal Transmission
The sensor sends a signal to the control unit to initiate the opening sequence.
Step 3: Door Activation
The control unit activates the motor, which pulls the door open along the track via a belt or gear system.
Step 4: Open Hold Time
The door remains open for a preset duration (e.g., 3–10 seconds) or until no more motion is detected.
Step 5: Closure
If no further movement is detected, the control unit commands the motor to close the door smoothly.
Step 6: Safety Check
During closing, safety sensors ensure nothing is in the path. If an obstruction is detected, the door will stop or reverse.
