Understanding Garage Door Sensors

Garage door sensors, also known as photoelectric sensors or photo eyes, are installed near the bottom of the garage door tracks. They work by emitting an invisible beam of infrared light between two units. When an object or obstruction interrupts the beam while the garage door is closing, the sensors detect the interruption and signal the garage door opener to stop and reverse the door’s movement. This safety feature prevents accidents and damage caused by the door closing on objects or people.

There are two main types of garage door sensors: photoelectric sensors and pressure (or contact) sensors. Photoelectric sensors use an infrared light beam to detect obstructions, while pressure sensors rely on physical resistance or pressure to detect objects in the door’s path.
