How do Automatic Doors Work?

As the world becomes increasingly automated, it’s no surprise that automatic doors are becoming more and more common in commercial buildings. These doors are designed to open and close on their own without the need for any human interaction. They can be installed in a wide variety of businesses, from storefronts, to offices, to airports. We’ll discuss how automatic doors work, why they’ve become so popular, how to maintain them, and ways automatic doors can benefit your business.

How Automatic Doors Work

Automatic doors work by using a variety of sensors and mechanisms that detect when someone is approaching the door to open and close it accordingly. The most common type of automatic door is the sliding door, which slides open and closed on a horizontal track. They are usually made of glass and metal, and they are most commonly used at business entry points and appear more inviting to customers and visitors.

Automatic doors can have two main types of sensors: motion sensors and pressure sensors. A motion sensor detects when someone is walking up to an automatic door and triggers the door’s mechanisms to open. The sensor triggers the door to close once the motion is gone. Pressure sensors, on the other hand, detect the weight of someone stepping on the ground in front of the door to trigger it to open.

In addition to these sensors, automatic doors also use a variety of small parts and mechanisms to open and close when triggered. Typically, they function with a motor at the top of the door that is connected to a system of gears by a belt or a chain. When the motor is triggered, it turns and pulls the door along the track.

Why Automatic Doors are Popular

We rely quite a bit on automation these days, and our doors are no exception. Originally invented to make moving around buildings easier for staff, automatic doors are often found in higher-end hotels, storefronts, and offices for their sleek appearance and ease of use. They are also popular in healthcare facilities, as they eliminate the need for people to touch the door and help prevent the spread of germs.

They can also help businesses save on energy costs. Since these doors automatically open and close, they eliminate the possibility of a door accidentally being left open and can help keep the building better insulated.

How to Maintain Automatic Doors

Like any piece of equipment, automatic doors require regular cleaning and maintenance. This ensures they stay working properly and last a long time. The biggest maintenance these doors need is regular cleaning. The sensors, glass, and tracks must be cleaned to ensure they work properly. A dirty sensor can struggle to recognize motion. Debris buildup on the track can cause the doors to struggle to move. Cleaning your automatic door will help it work properly consistently and for longer.

The mechanical parts of the door also need to be inspected every once in a while. The motor, gears, belts, and tracks all should be examined for signs of wear and tear that may need to be replaced. If you notice any issues, it’s important to contact your door technician to have it repaired!

Regular service is also important to maintaining your automatic doors. It can be easy to forget about inspecting your doors! Having your technician check on them every once in a while is a great way to ensure they stay perfectly functional and are repaired when needed.

How Automatic Doors Can Benefit Your Business

Automatic doors can have quite a few perks. Here are a few:

1. Easy Access

Automatic doors make it easy for customers, clients, and visitors to enter and exit your building. They don’t have to worry about which way the door swings, how heavy the door is, etc.

2. Modern Touch

These doors can instantly update the storefront of any building, making your entrance feel more upscale and polished.

3. Temperature and Energy

These doors can help regulate the temperature in your building by keeping the outside air from entering. This can also help reduce energy costs.

4. Cleanliness

Automatic doors are easy to clean because they are usually made of glass and metal. They’re also easy to keep clean, too. Because your visitors won’t have to touch the doors, they don’t accumulate germs and smudges nearly as fast as other types of doors can.


Automatic doors are an incredibly convenient door option for you and your business visitors. They can elevate your entrance, prevent the spread of germs, lower your energy costs, and make entering and exiting your business a breeze. By keeping them clean and well-maintained, they can last you quite a while, too.
