What is a genie garage door optical interrupt wheel?

A Genie garage door optical interrupt wheel is a component used in the safety system of garage door openers. It features a series of holes or slots that allow an optical sensor to detect the presence of an obstruction when the door is closing. If the sensor detects a change in light due to an obstruction, it signals the door to stop and reverse, enhancing safety by preventing accidents. This mechanism is crucial for ensuring that the garage door operates safely around people and objects.
