GPS-3 LHB Button Application

LHB-051A should be understood as a Mitsubishi elevator button replacement item, not a button expansion board or display PCB.

Compared with some newer button series, LHB-051A is often requested for older Mitsubishi elevator panels where the button style, rear plug position, and character plate structure must match the original unit.

Depending on the original elevator panel, this button may be used as:

• floor number button
• door open button
• door close button
• alarm button
• intercom button
• hall call button
• landing call button
• car operating panel button

The exact button function should be confirmed from the old button character, panel position, and rear wiring structure before ordering.

Shape, Character Plate and Plug Confirmation

LHB-051A should not be selected only by front appearance.

Before ordering Mitsubishi Elevator Button LHB-051A, please confirm:

• complete model number on the old button
• whether the old part shows LHB-051A or LHB-052A
• whether the version is G01, G02, G03, G11, G13, or G14
• round hole or square hole structure
• button character or symbol
• plastic letter, transparent plastic letter, or stainless steel letter
• front photo of the button
• back photo of the button module
• back plug or side plug structure
• illumination color if available
• whether it is used in COP, LOP, HOP, or landing call panel
• complete panel photo showing the installation position

This information helps avoid ordering a button with the correct front style but the wrong rear connector, letter plate, mounting structure, or panel fit.

Practical Replacement Notes

Do not replace this button only by the model family name.

LHB-051A and LHB-052A may appear together in market listings, but they should still be confirmed by the actual old button. A small difference in plug direction, mounting depth, hole shape, or character plate may affect installation.

If the button does not respond, technicians usually check the button contact, wiring harness, connector terminals, button board, and related signal circuit before confirming the button fault.

If the button light does not work, the cause may come from the lamp or LED circuit, the button module itself, the COP / LOP board, or the panel wiring.

For overseas buyers, sending clear front and back photos of the old LHB-051A button is the safest way to confirm the correct replacement before shipment.
