Where is the Sensor on an Automatic Door?

Automatic doors are a convenient and efficient way to allow people to enter and exit a building. The key to their automation is the presence of sensors that detect the presence of a person and trigger the door to open or close.

So where are these sensors located on an automatic door? In most cases, there are two types of sensors that are used:

• Presence sensors
• Activation sensors

Presence sensors are typically located in the door stiles and are sometimes called safety beams. Other presence sensors are mounted overhead on the door header and are designed to detect if anyone is standing in the threshold of the door way. Both sensor types typically use infrared technology in order to detect the presence of a person.

Activation sensors, on the other hand, are typically mounted on both sides of the automatic door header and detect when a person is actively trying to enter or exit. These sensors commonly use microwave technology to detect motion. When a person moves towards the automatic door it can detect the person’s motion. Newer automatic doors feature combination sensors which combine a motion activation sensor and a threshold detection presence sensor all in one.

Both types of sensors are essential to the proper functioning of an automatic door. Without them, the door would not be able to open or close automatically, which would defeat the purpose of having an automatic door in the first place.
