Our lift light curtain adopts advanced infrared sensing technology, forming a dense protective light grid across the elevator doorway. It detects passengers, goods and obstacles in real time, instantly reversing door movement to prevent pinching accidents. Featuring strong anti-interference, stable operation and long service life, it is compatible with most passenger lifts, freight lifts and residential elevators. Strict quality testing ensures reliable performance in long-term use.
· Full-height infrared light grid, 360° comprehensive anti-pinch protection.
· Ultra-fast response, sensitive detection, no blind spots.
· Excellent anti-interference capability, stable operation day and night.
· Easy to install & durable, wide compatibility with various elevator models.
