How Garage Door Sensors Work
Garage door safety sensors stop the door from closing on objects. They detect obstacles and send signals to the door opener. This prevents accidents and damage.
The sensors work by creating an invisible beam across the door opening. When something blocks this beam, the door will stop or reverse.
How Infrared Sensors Create A Safety Beam
Two sensors face each other on either side of the door. One sensor sends an infrared light beam. The other sensor receives this beam.
As long as the beam is clear, the door can close. If the beam breaks, the sensors tell the door opener to stop closing.
Wiring Connections Between Sensors And Door Opener
Sensors connect to the door opener with low-voltage wires. These wires carry signals to and from the sensors.
The wiring must be secure to avoid false signals or sensor failure. Proper wiring ensures the sensors work every time.
Power Supply And Signal Transmission
The sensors get power from the door opener unit. This power runs through the sensor wires.
Signal transmission happens instantly when the beam is blocked. This quick response keeps people and pets safe.
Common Types Of Sensors

These sensors protect you, your family, and your belongings by stopping the door from closing if something is in the way. Knowing how each sensor works can save you from costly repairs and potential injuries.
Photoelectric Sensors
Photoelectric sensors use a beam of light to detect objects in the path of the garage door. If the beam is broken, the door automatically reverses or stops closing. These sensors are popular because they are reliable and easy to install.
Have you ever noticed how the door stops when a pet or child crosses the threshold? That’s the photoelectric sensor at work, keeping everyone safe.
Pressure Sensors
Pressure sensors detect resistance when the garage door hits an object. These are usually installed on the bottom edge of the door. If the door meets an obstacle, the sensor triggers the door to reverse immediately.
These sensors are especially useful in busy garages where objects might be left on the floor. They add a layer of protection by sensing direct contact, not just a broken beam.
Infrared Sensors
Infrared sensors emit invisible rays that detect motion or heat near the door. When something passes through the sensor’s range, it sends a signal to stop or reverse the door. This technology is often used alongside photoelectric sensors for extra safety.
Imagine pulling your car into the garage and the door stops if a person suddenly appears. Infrared sensors provide that quick reaction to unexpected movement.
Magnetic Sensors
Magnetic sensors use magnets to detect whether the door is fully closed or open. They don’t detect obstacles but ensure the door operates correctly by monitoring its position. These sensors are crucial for alerting you if the door isn’t properly sealed.
Have you ever wondered why your garage door won’t close all the way? A faulty magnetic sensor could be the reason, signaling a misalignment or obstruction.
