What technology is used for automatic doors?

13 June, 2023

Automatic door mechanism technologies can vary. We discuss a few of these below.

Automatic doors enhance accessibility, energy efficiency, security and convenience in a range of buildings. They rely on a range of advanced technologies to operate smoothly and efficiently. Two of the key technologies used in the operation of automatic doors are the opening mechanism and sensors.

What are the different types of automatic door mechanisms?

Automatic sliding doors are an increasingly popular choice for many commercial and public buildings. They offer seamless entry and exit, conserve space, and have a stylish contemporary appearance.


There are different types of automatic sliding door mechanisms, including:

  • Belt Drive Mechanism

This automatic door mechanism uses a belt drive system to smoothly open and close the doors. It offers quiet operation that makes it particularly useful in settings where noise levels need to be managed.


  • Gear Drive Mechanism

Gear-driven automatic sliding doors use a set of gears to control the movement of the doors. They provide reliable and robust operation, making them ideal for high-traffic areas.


  • Telescopic Mechanism

Telescopic automatic sliding doors consist of multiple door panels that slide and stack upon opening. This automatic door mechanism maximises the door opening width, making it suitable for locations where space is limited.


  • Breakout Mechanism

Breakout automatic sliding doors have the ability to partially open in the event of an emergency or power failure. This feature allows people to manually push the doors open for a quick and safe exit.


What sensor is used in automatic doors?

A range of different types of sensors are used with automatic doors to detect the presence of people and to initiate the door’s opening and closing mechanism. The most common automatic door sensor used in automatic doors is the motion sensor. Motion sensors play a crucial role in detecting movement within the proximity of the door which then triggers the door’s response.

The types of sensors that are installed with automatic doors include:


  • Passive Infrared (PIR) Sensors

PIR sensors detect changes in infrared radiation emitted by moving objects such as people. They are commonly used in automatic door systems due to their reliability and effectiveness. PIR sensors work by detecting the heat signature of a person or object and then sending a signal to the door control system to activate the door’s opening sequence.


  • Microwave Sensors

Microwave sensors emit continuous microwave signals and measure the reflections caused by moving objects. They are capable of detecting motion through various materials and are often used in both indoor and outdoor automatic door applications. Microwave sensors provide a broader coverage area and are particularly effective in high-traffic locations or areas with varying environmental conditions.


  • Optical Sensors

Optical sensors use infrared or laser beams to detect the presence of people in the vicinity of the doors. These sensors emit a beam and measure the reflection or interruption caused by a person passing through the doorway. Optical sensors offer high accuracy and sensitivity and are suitable for both indoor and outdoor environments.
