GAA177HB2 Hall Sensor For Elevator Floor Position Detection & Leveling Control PNP NC 3100VF Elevator Spare Parts
Precise Leveling and Positioning (Core Function): Installed on the car side, in conjunction with the magnetic shielding plate in the hoistway, it monitors the car's position in real time. Upon reaching a floor, it outputs a signal to the control system, achieving precise leveling within ±1mm, ensuring a smooth, stepless stop and improving passenger comfort.
Speed Shifting and Door Zone Trigger: As the elevator approaches a floor, a deceleration signal is triggered in advance for smooth speed changes. After leveling, a door zone signal is output, allowing the car door to open; this is the safety trigger for automatic door opening.
Safety Interlock Protection: Doors are prohibited from opening when the elevator is not leveled to prevent falls. During operation, the position is continuously monitored, and protection is triggered in case of abnormalities to prevent "overshooting" or "bottoming out," making it a crucial component of the elevator safety circuit.
