Photocell is one of the most important safety components used in elevator doors to ensure passenger protection. It continuously monitors the door opening area using optical detection technology, helping eliminate the risk of trapping, collision, or injury during door operation.

Modern photocell systems create a protective detection zone across the elevator entrance, allowing reliable obstacle detection throughout the door passage area. This enables safe identification of passengers, wheelchairs, luggage, carts, and other objects before the doors close completely.

The system typically consists of transmitter and receiver units, connection cables, and a control interface. By generating an invisible infrared detection field across the doorway, the photocell continuously monitors movement within the entrance. When an obstacle interrupts the detection field, the system immediately sends a signal to the door controller, causing the door to stop or reopen.

Photocells are designed to provide reliable operation even in high-traffic environments. Their compact structure allows easy integration into elevator door profiles, making them suitable for both new installations and modernization projects.

Widely used in residential buildings, hospitals, hotels, shopping centers, and public facilities, photocell systems play a vital role in meeting elevator safety requirements and improving passenger protection.

Photocell is an essential elevator safety solution that helps ensure safe door operation, prevent accidents, and provide reliable passenger protection.
