YG-25 G1 Magnetic Proximity Leveling Sensor U-Slot Elevator Floor Position Switch 250V 3A Lift Replacement Safety Spare Parts

YG-25 G1 is a U-slot magnetic proximity leveling sensor exclusively designed for Mitsubishi passenger elevators, also known as permanent magnet leveling switch. It adopts built-in dry reed tube magnetic induction principle, no power required for sensing trigger. The flame-retardant black plastic housing and galvanized metal bracket feature IP67 dustproof & splashproof performance, strong anti-vibration and anti-electromagnetic interference capacity, stable signal output even in complex hoistway environment. It matches all mainstream Mitsubishi elevator control systems, standard installation hole position for direct replacement without modification.

Precise Floor Level Position Detection
When the magnetic leveling vane passes through the U-slot, the internal reed tube switches on and sends position signal to elevator mainboard. It achieves millimeter accurate car floor stop to eliminate tripping risks for passengers.
Door Opening Safety Interlock Control
The control system only permits car and landing door opening after receiving complete leveling signal. It locks door circuit while elevator running to prevent dangerous half-open door operation.
Elevator Position Calibration Reference Signal
Provides fixed floor reference point for main control system to correct cumulative position error, effectively solve floor deviation, mis-landing and floor skipping faults.
Running Speed Deceleration Trigger
Transmits deceleration signal in advance when the car approaches target floor, enabling smooth slow-down and stable stop without elevator shaking.
Fault Alarm & System Protection
If sensor signal loss or abnormal triggering occurs, the elevator will trigger fault code and limit operation, reminding maintenance staff to replace parts timely and avoid safety hazards.
