• Photo Eye Sensor

  This is a safety device that prevents the elevator door from closing on passengers or objects in the doorway. It consists of two parts: a transmitter and a receiver. The transmitter sends a beam of light across the doorway. When an object interrupts the beam, the receiver detects it, and the door will reverse and open.

• Safety Edge

  The safety edge is installed on the bottom of the elevator door. It is a pressure-sensitive strip that works like a photocell. If an object or person is in the way when closing, the safety edge will sense the pressure and automatically reverse the door to prevent injury or damage.
