How Do Automatic Doors Work?

Here at ABC Industrial we know that a lot of our customers are shopping for something other than roller shutters, which is why we have such an extensive product line. In fact, our range of automatic doors are the best of the best when it comes to efficiency, durability and charisma. But how exactly do they work? Fret not, the ABC team are on hand to tell you everything you need to know…


Automatic doors work using sensors that are able to detect when a person is approaching them. In fact, various types are used. For example, optical sensors are put into place in order to signal the opening and closing of the doors whilst other sensors are placed near the sides in order to track motion. A particular type of sensor known as a pressure sensor acts like a scale that detects a large amount of pressure around the doors and if that weight exceeds its programming the doors will open. This type of sensor can also be considered a secondary sensor too.


Whilst sensors are used to detect a person’s presence, it is the opening and closing mechanisms that actually drive the doors to allow people through in either direction The mechanism is often attached via a cog or auxiliary drive to the doors and then connected using rubber belts that are able to manipulate the doors function.  If the automatic doors are a sliding variety however then rollers are put into place. One of the biggest problems of the modern world is trying to keep up with the technological advances that are released each year. After all, automatic doors are surely a modern invention! With this said, they offer a range of great benefits such as allowing us to operate hands free, keeping buildings warmer where people have a tendency to leave regular doors open and improving the efficiency of foot traffic.
