GAA177HB2 Hall Effect Leveling Sensor

The GAA177HB2 is a magnetic hall effect sensor designed for elevator floor position detection and leveling control. Installed on the car side, it works with magnetic shielding plates in the hoistway to provide precise ±1mm leveling accuracy and speed shift signaling.

Key Features

• ±1mm Precise Leveling: Hall effect sensing with magnetic shielding plates ensures accurate floor alignment and stepless stopping
• Dual Function Output: Provides both leveling position signal and speed shift point detection for comprehensive motion control
• PNP NC Output: PNP normally-closed output configuration for fail-safe operation in safety-critical applications
• Magnetic Sensing: Non-contact magnetic detection immune to dust, oil, and ambient light for reliable long-term operation
• 3100VF Compatible: Designed for compatibility with 3100VF and similar elevator control systems
