OTIS Photoelectric Sensor DAA629F2 Elevator Leveling Switch Floor Position Detection & Door Safety Control Original Lift Spare Parts
Precise Floor Leveling (Main Function)
Detects the leveling vane at each floor, sending real‑time position signals to the mainboard. Ensures ±1mm accurate leveling, eliminating tripping hazards and improving passenger comfort.
Door Safety Interlock Control
Interlocks with door circuits: only when the sensor confirms full leveling can doors open; prevents door opening mid‑travel and ensures safety.
**Floor Position Calibration & Correction
Acts as a floor reference point, helping the system calibrate position data, correct cumulative errors, and avoid mis‑leveling or floor skipping.

Elevator Sensor – FAQs
Q1: What types of sensors are commonly used in elevator systems?
Elevators use sensors for position detection, leveling, door monitoring, and other control functions. Common sensing technologies include magnetic, inductive, and photoelectric types, depending on the application.
Q2: Can elevator sensors with the same appearance be interchangeable?
Not necessarily. Similar-looking sensors may differ in sensing principles, supply voltages, output logic, detection distances, or connector arrangements.
Q3: What is the difference between NPN and PNP sensor outputs?
NPN and PNP sensors use different transistor output configurations. The correct type depends on the input circuit and wiring requirements of the elevator controller.
Q4: What can cause an elevator sensor to provide an incorrect signal?
Possible causes include incorrect alignment, damaged wiring, unstable power supply, contamination, electrical interference, or sensor failure. The connected controller and sensing target should also be checked.
Q5: What information is required to identify a replacement elevator sensor?
Please provide the original part number, sensing type, supply voltage, output signal, sensing distance, mounting dimensions, and connector details.
