LC-MV59X Hall Proximity Sensor for Elevator Load Detection
Non-contact magnetic sensing for movable-car-bottom load detection, with a 2–9 mm sensing-distance range, 12–24 VDC supply and relay output.
Product Overview
LC-MV59X senses a magnet fitted to the movable car bottom without mechanical contact. The threaded cylindrical body and mounting nuts allow its sensing face to be positioned relative to the magnet.

Dimensions and Installation
The complete dimension drawing identifies the sensor body and lead-end dimensions. All dimensions shown are in millimetres.
The sensor and magnet are arranged beneath the movable car bottom. The installation illustration shows the sensing location, mounting support and 2–9 mm effective movement range.
- Prepare a suitable mounting support for the sensor.
- Position the assembly near the middle of the movable car bottom where practicable.
- Attach the magnet with its marked face directed towards the sensor.
- Align the magnet with the centre of the sensing face and keep both faces parallel.
Frequently Asked Questions
How does LC-MV59X detect the elevator load condition?
The Hall proximity sensor detects a magnet fitted to the movable car bottom. Movement changes the magnet-to-sensor gap; the sensor provides a relay signal for the load-detection arrangement.
What power supply and output does it use?
LC-MV59X uses a 12–24 VDC supply and provides relay output with one normally closed contact and one normally open contact.
What sensing gap and cable length are specified?
The specified sensing-distance range is 2–9 mm. The pre-wired cable has a standard length of 1.2 m.
How should the sensor and magnet be positioned?
Position the sensor near the middle of the movable car bottom where practicable. Align the marked face of the magnet with the centre of the sensing face and keep the two faces parallel.
