Passengers judge an elevator by how level the car stops. The YX401C097-01A leveling sensor is Mitsubishi’s ±1 mm precision eye, originally designed for NPX, NEX and GVF-L systems. This 24 VDC, 4–20 mA inductive probe continuously measures car-to-landing distance and feeds real-time corrections to the VVVF drive, eliminating the need for mechanical cams or magnets. Nanjing Zhuye Elevator Parts keeps factory-calibrated YX401C097-01A units in anti-static stock for next-day despatch. Below we explain what the sensor does, how to install it in under ten minutes, and the replacement cycle that prevents expensive “out of level” call-backs.
1. What YX401C097-01A Really Is
-
Principle: high-frequency inductive, 2 mm sensing face, non-contact
-
Range: 0–20 mm, linear 4–20 mA, 12-bit resolution (±1 mm)
-
Supply: 24 VDC ±10 %, ripple <200 mV, 20 mA consumption
-
Output: 4–20 mA loop, 500 Ω max load, short-circuit protected
-
Body: M18 × 1 mm stainless, IP67, -25 °C to +70 °C
-
Cable: 3 m PVC, oil-resistant, 4-way M12 plug, gold-plated pins
-
Approvals: CE, RoHS, REACH, UL file E501843
If the signal drifts >±2 mm, the controller logs “Level Deviation” and re-levels before opening doors.
2. Where It Is Used
-
Mitsubishi NPX, NEX, GVF-L passenger elevators 1.0–2.5 m s⁻¹
-
Machine-room-less (MRL) or machine-room (MR) installations
-
New build or modernisation — one part number fits all guide rails 16–19 mm
-
Suitable for indoor shopping malls, outdoor scenic lifts, coastal high-rise
3. Installation – 10-Minute Plug-and-Play
Safety: place lift on inspection, lock main breaker, tag out, prop car to floor level.
-
Remove old sensor — unscrew M18 × 1; unplug 4-way M12.
-
Clean mounting face — remove rust, paint, oil; check gap 2–3 mm to rail web.
-
Hand-tighten YX401C097-01A until face touches rail, back off ½ turn (gap ≈1 mm).
-
Connect M12 plug — brown +24 V, blue 0 V, white 4–20 mA, black shield.
-
Power on — green LED steady; multimeter reads 12 mA ±0.5 mA at floor level.
-
Run one full trip — verify 4 mA at bottom, 20 mA at top, 12 mA at every landing.
No laptop is required; zero and span are pre-calibrated at the factory.
4. Daily Operation – What the Sensor Actually Does
-
Samples gap every 1 ms; averaged over 10 ms to eliminate vibration noise
-
Auto-compensates for temperature; built-in 20 °C reference
-
Built-in self-test every 24 h — if output <3.8 mA or >20.2 mA, “Level Sensor Fault” is logged
-
IP67 stainless body resists pressure washing and coastal salt spray
-
Consumes 20 mA — meets EN 81-20 standby power limits
5. Replacement Cycle & Preventive Maintenance
-
High-speed office (>1,000 starts day⁻¹) – inspect every 6 months, replace sensor every 5 years
-
Residential tower (300–600 starts day⁻¹) – inspect annually, replace every 8 years
-
Low-rise freight (≤200 starts day⁻¹) – inspect every 18 months, replace every 10 years
Replace immediately if:
-
Zero drift >±1 mm after re-teach
-
Output ripple >50 µA (oscilloscope test)
-
Cable insulation cracked or oil-soaked
-
LED off with 24 V present
-
Housing temperature >85 °C with normal ambient
6. Extending Life – 3 Pro Tips
-
Keep gap 1–2 mm; smaller gap causes saturation, larger gap reduces resolution
-
Wipe sensor face monthly; brake-dust paste absorbs HF signal
-
Torque M18 to 25 N·m; over-tightening crushes the O-ring
7. Why Buy YX401C097-01A from Nanjing Zhuye Elevator Parts?
-

-
Pre-calibrated; matches Mitsubishi original zero/span, no re-teach required
-
Anti-static foam box + silica gel — safe for air freight
-
Dual stock: 420 pcs Nanjing, 150 pcs Dubai — next-day delivery to 65 countries
-
Bundle kit: sensor + 3 m M12 cable + 22 mm lock-nut — 5 % discount
-
24 months warranty against drift or leakage
-
7×24 WhatsApp/WeChat video support; average response 10 minutes
Conclusion
The YX401C097-01A leveling sensor is the invisible eye that guarantees perfectly flat landings. A single millimetre of drift can trigger re-levels, callbacks and one-star reviews. Stock a spare from Nanjing Zhuye on every service truck, swap it on schedule, and replace “out of level” panic with a five-minute planned fix — one perfectly flat entrance at a time.
