Mitsubishi MRL Elevator LOP YA129A389G03L11002

Mitsubishi MRL Elevator LOP YA129A389G03L11002 is a landing operating panel used in Mitsubishi machine-room-less elevator systems.

The LOP is installed at the elevator landing side, where passengers use the call button to request the elevator. Depending on the elevator configuration, the panel may also include direction indication, floor display, call registration light, or other landing-side signal functions.

The main model reference for this page is:

• YA129A389G03L11002

Because this model number is highly specific, replacement should be confirmed by the old panel label, button layout, display style, connector structure, and landing installation position.

Application in MRL Elevator Systems

Machine-room-less elevators use a compact system layout where major equipment is arranged without a traditional machine room. Mitsubishi describes MRL elevators as systems that use gearless traction equipment located in the hoistway, helping reduce building space requirements.

For this reason, landing-side components such as LOP panels must match the original elevator control system and wiring configuration. A panel with similar appearance may still have different signal wiring, button logic, display format, or connector arrangement.

What Buyers Should Confirm

Before ordering Mitsubishi MRL Elevator LOP YA129A389G03L11002, please confirm:

• Complete model number: YA129A389G03L11002
• Front photo of the old landing panel
• Back photo of the panel or PCB
• Button quantity and button direction
• Display type if included
• Connector quantity and wiring direction
• Panel size and mounting hole position
• Floor installation position
• Whether the panel is used for up call, down call, or up/down call

This information helps distinguish the correct Mitsubishi landing operating panel from other similar LOP, HOP, or outbound call panels.

Landing Panel Replacement Notes

A landing panel problem may appear as a button fault, display fault, or signal response problem.

Maintenance teams may inspect the LOP when there are symptoms such as:

• hall call button not responding
• call registration light not working
• landing display not showing correctly
• direction indicator abnormality
• loose connector or damaged wiring
• physical panel damage
• intermittent landing call signal

These symptoms are not always caused by the panel itself. The landing button, PCB board, display unit, wiring harness, power supply, and controller signal line should also be checked before confirming replacement.

Practical Supply Reminder

Do not select YA129A389G03L11002 only by appearance.

Mitsubishi landing operating panels may look similar from the front, especially when the faceplate style, button type, and display window are close. However, the rear PCB, connector layout, and signal definition may be different.

For overseas buyers, the safest confirmation method is to provide clear photos of the original LOP front side, back side, label area, connector area, and installation position before shipment.
