Photocell

Photocells, also known as photoelectric sensors, serve as integral safety devices within elevator systems, specifically in relation to door operations. These sensors utilize infrared or visible light to detect obstacles or obstructions in the path of the elevator doors.

Installed near the elevator door edges, photocells emit beams of light across the doorway. When an obstruction interrupts this beam, the sensor detects the interruption and triggers the door to either stop closing or reopen, preventing the doors from closing on passengers or objects.

These sensors are meticulously designed to enhance safety by ensuring that elevator doors operate smoothly and securely. By swiftly detecting any obstruction, whether it's a person, an object, or any other obstacle, photocells play a crucial role in preventing accidents and minimizing the risk of injuries within the elevator.

Photocells significantly contribute to passenger safety and convenience by providing an added layer of protection against door-related accidents. Their ability to detect obstructions and promptly halt door movements ensures a safer and more reliable elevator experience for passengers, making them an essential safety feature in modern elevator systems.
