Otis Floor Sensor HAA629F1/F2/F3/F4/F5 – Precision Floor Detection for Smooth, Safe Landings | Nanjing Zhuye Elevator Parts
Every smooth landing starts with a precise signal. The Otis HAA629F-series floor sensors—F1, F2, F3, F4 and F5—are the eyes that tell the controller exactly where the car is in the shaft. Whether it’s a magnetic, inductive or photoelectric version, each sensor outputs a rock-solid signal to within ±1 mm, ensuring levelling accuracy and preventing overrun faults. When a sensor drifts or fails, the car can overshoot, undershoot, or stop between floors. Nanjing Zhuye Elevator Parts keeps the complete HAA629F range in stock, pre-calibrated and ready for same-day despatch—helping you restore perfect landings without costly OEM delays.

Installation method – 10-minute precision swap
-
Place lift on inspection mode; stop car 200 mm above target; switch OFF local breaker; lock & tag.
-
Clean old sensor and target; photograph wiring polarity.
-
Release M12 lock-nut; slide old sensor out; note gap sticker.
-
Insert new HAA629F× until face touches target; back off 2 mm; lock nut 15 Nm.
-
Connect 24 V DC (brown +, blue −); verify LED changes state when target passes.
-
Hand-jog car past floor; oscilloscope shows clean 0-24 V square wave, rise time < 1 µs.
-
Run full-speed pass; levelling error must be ±1 mm vs. tape zero.
-
Apply torque-stripe paint; log gap value and serial number in maintenance book.
Replacement cycle & preventive maintenance
Otis bulletin SB-SEN-2024-05 recommends:
-
Visual inspection every 6 months: check for cracks, cable oil-swelling, LED status.
-
Gap measurement: replace when gap > 4 mm or when levelling error > ±2 mm.
-
Replace every 5 years or 1 million cycles in high-traffic (> 1 000 starts/day).
-
Immediate replacement if:
– LED off while 24 V present and target present,
– switching delay > 1 ms,
– insulation < 1 MΩ between wire and shield,
– housing cracked exposing live parts.
Pro tip: 70 % of premature failures are traced to misaligned targets—re-align every year.
Maintenance tips from Nanjing Zhuye Elevator Parts
-
Always use gold-plated M12 connector for 24 V DC; tin contacts oxidise and cause missed floors.
-
Never apply WD-40; it attracts dust and changes magnetic properties.
-
Keep a box of HAA629F1/F2/F3/F4/F5 in every service van; at 45 g it costs less than one callback.
-
After lightning storm, check 24 V ripple < 1 V; high ripple burns the sensor IC.
-
Order the “Sensor Kit” (sensor + M12 connector + target sticker) from Nanjing Zhuye Elevator Parts to eliminate parts hunting and ensure matched components.
