The recommended height for installing electronic eye sensors of garage door openers is 4 to 6 inches above the garage floor. This specific height is crucial for effective operation as it allows the sensors to detect any obstruction in the garage door's path. Positioning the sensors too high or too low can lead to malfunction or failure to stop the garage door from closing on objects or individuals. By installing the sensors within the 4 to 6 inches range, the system can better achieve its safety function, reducing the risk of accidents caused by the door closing when there is something in its way. This height also helps ensure that the sensors work correctly in most typical home garage settings, balancing between sensitivity to obstructions and preventing false readings from dust, small debris, or pets.
