Automatic doors are a part of our everyday lives, so it would be hard to imagine going to a supermarket and having to open the door yourself with a full trolley. They allow easy access to buildings for those with disabilities, and they promote high levels of hygiene as they eliminate the need for physical contact. But how do they actually work? In this blog post, we will go through the mechanics and fundamentals of how automatic doors work.

How Automatic Doors Work

Automatic doors open automatically as soon as a person approaches them. However, all types of automatic doors have different levels of sophistication and complexity. They all require a sensor to activate their opening and closing. When the sensor detects a cue, it sends a signal to the door operating mechanism.

Sensors

All automatic doors are equipped with sensor systems which detect a person or object in their vicinity. They use different technologies, such as microwave pulses or passive infrared sensors to detect movement, which then sends a signal to the operating mechanism to open the door.

Operating Mechanism

The operating mechanism is the brain behind how the sensors are triggered. It is powered by an electric motor, which, in turn, opens the door according to the specific type you have. The speed, timing, and direction are determined to allow the door to open smoothly and safely, so people can pass through with ease.

Activation Methods

Automatic doors are activated through the following methods:

  • Motion Sensors: These sensors detect movement within a designated range. When a person approaches the door, the sensors trigger the door to open.
  • Push Buttons: These allow users to open a door by pressing a button.
  • Proximity Sensors: These rely on a signal from a key card, a fob, a smartphone, or any other device that has been programmed to allow access to specific areas.
  • Pressure Mats: Installed on the floor near the door, they detect the weight of a person standing on them.

Types Of Automatic Door Mechanisms

  • Sliding Doors: Operate on a track system with panels that slide horizontally to open or close.
  • Swinging Doors: Pivot on hinges to fold back onto themselves to open or close.
  • Revolving Doors: Move continuously to allow multiple people to enter or leave at a time.

Safety

When it comes to automatic doors, safety is a priority. There are specific safety measures in place to prevent accidents.

  • Safety Sensors: Additional sensors are installed near the edges of the door to detect any obstructions.
  • Emergency Opening: In case of power failure or emergencies, automatic doors are equipped with manual override mechanisms, allowing people to open the door manually.
