How Do Garage Door Sensors Work

The traditional form of sensor is mechanical in which a moving garage door reverses due to physical contact with an object but photoelectric sensors have become mainstream.

How do garage door sensors work.

If the sensor doesn t receive the beam emitted by its opposite number the door won t close. They can also prevent damage to the garage door and the garage system itself. In turn the electric motor engages a track and pulley system which then opens or closes your garage door. This system allows them to detect obstructions like your car or a kid on a bike.

They are part of the automatic garage door system. When the device detects any person or object in the path of a closing garage door it signals the motor to stop the downward action and switch the motion into reverse to stop the obstacle being crushed. Do both garage sensors need to be green. How garage door sensors work in the majority of cases a photo eye sensor will be installed on the garage door sensor.

Garage door sensors protect your family possessions and pets by not allowing the heavy garage door to close if there is anything in the glide path. The infrared beam from the garage door opener sensors isn t able to be seen by human eyes. The sensors are normally about 4 inches above the ground. In general garage door sensors block the door from closing if there is an object nearby.

They do this by using an electric eye sensor that crosses the doorway. When you press the remote control you use to open your garage door it sends a signal to the sensors to open the door. The purpose of a photo eye sensor is to detect if anything is blocking the path of the garage door. They notify your garage door system of any potential obstruction that would disrupt the downward trajectory of the garage door.

In fact these safety sensors have been required by law since 1993. These infrared sensors are placed on either side of your garage door about two to six inches off the ground. Photo eye sensors detect objects as well as people. The units are placed near the ground on either side of the garage door.

If the beam of light is interrupted while the garage door is closing the door will stop and rise back up. The infra red sensors that facilitate your garage door opening system are placed on either side of your garage door doors and they stand approximately six inches off of the ground. Garage door sensors work with the use of a photo eye system. As long as the beam isn t interrupted the door will open or close normally.

This precaution ensures that the door doesn t close when your car is in the doorway. The same mechanism kicks in when other objects are placed near the door too. What do garage door safety sensors do. Your garage door sensors perform a vital function.

Safety sensors were invented as a result of accidents happening with automatic doors coming down on top of people cars and animals. Garage door sensors utilize a photo eye sensor and a beam of infrared light that goes between the two units.
