KONE Elevator Leveling Sensor 77U 77N 77S 61U 61N – 1 Pack
KONE Elevator Leveling Sensor 77U 77N 77S 61U 61N – 1 Pack
KONE-Compatible Elevator Leveling Sensor – 77U / 77N / 77S / 61U / 61N
Keep your elevator running smoothly and stopping precisely at every floor. This high-reliability magnetic induction leveling sensor is engineered as a direct-fit replacement for KONE elevator systems, offering accurate floor-detection signals, a rugged build, and straightforward installation — all in a single pack.
Key Features
- Impact & Pressure Resistant Construction: Reinforced steel pipe internal structure combined with a high-strength, flame-retardant engineering plastic housing effectively resists collisions, compression, and dust infiltration during installation and long-term operation — extending service life and reducing maintenance costs.
- Accurate Leveling Detection: Built-in high-precision magnetic induction core components output stable, accurate floor-position signals under normal operating conditions, ensuring the elevator car stops smoothly and precisely at each designated floor level.
- High-Quality 1.5 m Connection Cable: Oxygen-free copper conductors wrapped in a wear-resistant, anti-aging PVC insulating sheath deliver low-loss, interference-free signal transmission — minimising cable replacement frequency and simplifying on-site wiring.
- Multi-Model Compatibility: Available in models 77U, 77N, 77S, 61U, and 61N with a standard M12 thread mounting structure, perfectly fitting KONE series elevator leveling systems across a variety of installation positions.
- Wide Voltage Adaptability: Premium high-load electronic components support working voltages up to 250 V, adapting reliably to varying elevator power supply environments and reducing failure rates caused by voltage fluctuations.

Frequently Asked Questions
Q: Which elevator models is this leveling sensor compatible with?
A: This sensor is designed for compatibility with KONE elevator systems. It is available in models 77U, 77N, 77S, 61U, and 61N (Normally Closed) with a standard M12 thread mount, covering a wide range of KONE series leveling system configurations.
Q: What does "Normally Closed" (NC) mean for this sensor?
A: A Normally Closed sensor maintains a closed (conducting) circuit in its default state. When the magnetic target (vane/plate) passes through the sensor's detection zone, the circuit opens, sending a signal to the elevator control system to indicate the floor-level position. Always verify that your KONE elevator controller requires an NC-type sensor before ordering.
Q: How is this sensor installed?
A: The sensor features a standard M12 thread mounting structure, allowing it to be threaded directly into the existing mounting bracket on the elevator car or shaft. Connect the 1.5 m PVC-sheathed cable to the corresponding terminals on your elevator controller. Always follow your local elevator maintenance regulations and have installation performed by a qualified elevator technician.
Q: What voltage range does this sensor support?
A: This leveling sensor supports working voltages up to 250 V, making it suitable for a wide range of elevator power supply environments and accommodating typical voltage fluctuations found in commercial and residential elevator installations.
