Where should garage door opener electronic eye sensors be installed for proper function?

The appropriate installation height for garage door opener electronic eye sensors is crucial for their effective operation. Installing the sensors 4 to 6 inches above the garage floor ensures they can accurately detect obstructions in the path of the garage door without being too high, which may allow small objects to pass under them, or too low, which could lead to false triggers from debris on the floor.

Positioning the sensors within this height range allows for optimal functionality. At this level, the sensors are still close enough to the ground to detect people, pets, or objects that could block the door's path, significantly enhancing safety by preventing accidents. The design of most garage door systems anticipates this height to ensure reliability and compliance with safety standards.

Options that suggest mounting the sensors either lower or higher than this range may lead to decreased effectiveness and safety hazards, as they could miss detecting smaller obstructions or be falsely activated by movement or reflections at inappropriate heights.
