WECO Elevator Light Curtain 917A61-AC220V
The WECO 917A61-AC220V is a high-sensitivity light curtain designed for elevator car door anti-pinch safety protection. Using real-time infrared detection, it monitors the door closing area and automatically triggers door rebound when passengers or objects are detected, preventing pinching injuries.
Key Features
- Infrared Obstacle Detection: Dense infrared beam array creates a continuous detection curtain across the entire door opening
- Automatic Door Rebound: Instantaneously signals the door controller to reverse direction when any obstacle is detected
- AC220V Direct Power: Operates directly on standard 220V AC elevator cabinet power without additional transformer
- Strong Anti-Interference: Shielded design prevents false triggering from ambient light, dust, and electromagnetic noise
- Long-Life Operation: Designed for millions of door cycles in high-traffic elevator applications
