KONE Elevator Leveling Sensor 61U 61N KM86420G03 DS-25

KONE 61U / 61N KM86420G03 DS-25 is a U-shaped electronic leveling sensor used in compatible KONE elevator shaft-positioning systems.

The sensor detects the corresponding vane or triggering plate as the elevator car approaches the landing. Its signal helps the elevator control system identify the leveling or positioning area.

KONE officially describes KM86420G03 as an Electronic Shaft Switch Oscillator. In the elevator spare-parts market, it is also commonly called:

• KONE 61U Sensor

• KONE 61N Sensor

• KONE DS-25 Leveling Sensor

• KONE KM86420G03

• KONE U-Type Leveling Switch

• Elevator Shaft Position Sensor

• Elevator Leveling Inductive Sensor

Confirm 61U and 61N Before Ordering

The 61U and 61N sensors may be supplied as a matched set or as separate versions, depending on the original installation. Their wiring definition, signal type, connector, and mounting position should be checked carefully.

Before ordering, please provide:

• KM86420G03 label

• 61U or 61N marking

• DS-25 model marking

• complete sensor photos

• connector and wire configuration

• cable length

• mounting-hole spacing

• sensor-slot dimensions

• installed-position photo

• triggering vane photo

• controller information

• quantity required

A sensor with the same U-shaped housing may still use a different PNP/NPN signal type, connector definition, or mounting arrangement. It should not be selected by appearance alone.

Replacement may be considered when the elevator has unstable leveling signals, intermittent shaft-position detection, damaged wiring, broken housing, or inconsistent sensor response. Technicians should also inspect the triggering vane, mounting clearance, bracket alignment, connectors, power supply, and shaft wiring.

Installation and functional testing should be completed by qualified elevator technicians. The elevator’s leveling accuracy and related positioning signals must be checked before normal operation resumes.

For buyers in Saudi Arabia, Jordan, Egypt, Iraq, UAE, Kuwait, Brazil, Colombia, Spain, and Italy, clear photos of the old sensor, connector, and triggering vane are recommended before shipment.

FAQ

Is KM86420G03 a photoelectric sensor?

It is commonly marketed as a photoelectric or U-type leveling sensor, while KONE officially calls it an Electronic Shaft Switch Oscillator. The original signal and wiring configuration should be confirmed.

Are 61U and 61N the same sensor?

They belong to the same leveling-sensor system, but their signal or installation position may differ. Do not assume they are interchangeable without checking the old markings and wiring.

Can another DS-25 sensor replace it directly?

Not automatically. Confirm the voltage, PNP/NPN signal type, connector, cable, slot size, and mounting dimensions first.

What photos should I send?

Please send the full label, connector, cable, front and side views, installed position, and the related triggering vane.
