What is an elevator door sensor?
The elevator door sensor is typically a small electronic device used to detect the status of the elevator door and ensure safety. These sensors are usually located at the edge or above the elevator door and can be photoelectric sensors, contact switches, or pressure sensors. Their main function is to detect whether a person or object is blocking the door from closing, thus preventing accidental injuries. Visually, elevator door sensors may appear as small square or circular modules, housed in plastic or metal casings. Their primary role is to ensure safety by preventing the door from closing when someone or something is in the way, avoiding injuries. Additionally, the sensors ensure that the elevator does not operate when the door is not fully closed, enhancing passenger safety.
