The Curtain Of Light Elevator is a photoelectric safety detection system designed to protect passengers during elevator door closing operations. It forms a dense infrared beam network across the elevator door opening to detect any obstruction and immediately trigger a door reopening signal.
This system is widely used in passenger elevators, modernization projects, and maintenance replacements where reliable door safety performance is required.
It is designed for OEM manufacturers, elevator integrators, maintenance companies, and global distributors requiring stable supply and standardized technical compatibility.
