Automatic doors, a familiar sight in our daily lives, are frequently disregarded, despite their importance in modern infrastructure. These doors, which open automatically as a person approaches, have transformed accessibility and convenience in both business and residential environments. This article goes into the world of automatic doors, covering their history, mechanisms, types, benefits, and potential future developments.
History
When were automatic doors invented?
The notion of automatic doors dates back to the first century AD, when mathematician Heron of Alexandria in Roman Egypt is credited with creating the first known mechanical door. His invention used heat from a fire to create air pressure in a brass jar, which then pumped water into nearby containers. These containers served as weights that, via a sequence of ropes and pulleys, opened the temple’s doors about the time people were supposed to arrive for worship.
Evolution and Modern Advancements?
Engineers Horace H. Raymond and Sheldon S. Roby of Stanley Works created the contemporary automatic door in 1931. The patent can be found here. They created the first model of an optical device that activated the opening of an automatic door, which was put at Wilcox’s Pier Restaurant in West Haven, Connecticut. Dee Horton and Lew Hewitt designed the first sliding automatic door in 1954, with a mat actuator. They co-founded Horton Automatics Inc. in 1960 and introduced the first commercial automatic sliding door to the market. Microwave motion detectors became widely used in automated doors when the Gunn diode was invented in the 1970s. In 1980, the first automatic doors using an infrared sensor were Introduced.

How Automatic Doors Work?
Automatic doors are a common feature in both business and residential buildings, offering a simple and hands-free entry and exit. But how do these doors work? Automatic doors operate using a mix of sensors, motors, and control systems.
Sensors & Trigger Mechanism
The sensor is the primary component of an automatic door system. Sensors are devices that detect motion or presence in a given location. Automatic doors use a variety of sensors, which include:
- Microwave Sensors: produce microwave pulses and measure their reflection off a moving object. When a person or object approaches the door, the time required for reflection changes, causing the door to open.
- Infrared Sensors: operate by emitting infrared light. When a person or item interrupts this light, the sensor alerts the door operator to open the door.
- Pressure sensors: are commonly utilized in mat actuators. When someone steps on the mat, the pressure causes the door to open.
Door Operators & Mechanism
The door operator is activated when the sensor causes the door to open. The motorized mechanism that opens and closes the door is called the door operator. Different kinds of door operators are needed for various kinds of doors, including swing, revolving, and sliding doors.
When sliding doors are used, the operator usually moves the door along a track using a chain drive, gear, or belt. A mechanical arm is used by swing door operators to push or pull the door open. Typically, a motor located in the central shaft of a rotating door rotates the door.
Control Systems
The automatic door’s brain is the control system. It gives commands to the door operator after receiving inputs from the sensors. The speed at which the door opens and closes, the amount of time it takes for the door to begin closing, and the hold-open duration are all programmable in the majority of control systems.
Safety Features
One important feature of automatic doors is safety. Safety sensors used in the majority of automatic doors stop the door from closing in the event of an impediment. In the event of a power outage or other emergency, certain doors also contain a manual override feature that enables manual door opening.
Sensors, door operators, and control systems all work together seamlessly to operate automatic doors. Together, these elements offer a practical and secure route for both people and cargo.
