OTIS Elevator Leveling Sensor GAA177HB1
The OTIS GAA177HB1 is a high-sensitivity photoelectric leveling sensor specifically designed for OTIS elevator floor position detection. It accurately captures the car position signal relative to landing level and transmits stable feedback to the main control board for precise leveling control.
Key Features
- ±1mm Leveling Accuracy: High-precision photoelectric detection ensures accurate floor alignment for passenger safety and comfort
- Fast Response Time: Millisecond-level signal transmission enables real-time position correction during elevator deceleration
- Anti-Interference Housing: Shielded sensor body prevents false triggering from ambient light and electromagnetic noise
- Durable Construction: Industrial-grade components rated for millions of detection cycles in harsh elevator environments
- OTIS Direct Replacement: Plug-compatible with OTIS leveling plate and vane systems for easy installation
