Liftmaster MA002, CONNECTOR, 12 PIN
The LiftMaster MA002 is a 12-pin connector used as a removable wiring terminal strip on select LiftMaster gate and barrier operator control systems. Connectors like this are small parts, but they matter because loose or damaged terminals can create intermittent inputs, accessory failures, false commands, or hard-to-trace control problems. MA002 is commonly seen in Mega Arm and Mega Arm Tower service parts, including MADCBB, MATDCBB, and related DC barrier gate operator families where the parts diagram calls for a 12-pin removable connector. It is also searched as MA-002. Before replacing it, confirm that the control board uses the same 12-pin layout and that the problem is not actually a damaged board header, broken field wire, or incorrect accessory wiring.

Technician Note
If the connector is burned, melted, or repeatedly loosens, inspect the wire size, terminal torque, connected accessory, and board header before replacing only the plug.
Before Ordering Checklist
- Confirm the connector is 12 pin.
- Match the board location and terminal orientation.
- Inspect the board header for bent or damaged pins.
- Label all wires before removing the old connector.
- Verify each accessory input after reconnecting wiring.
Professional Advisory
Low-voltage control wiring should still be handled carefully. Incorrect accessory wiring can damage boards or create unsafe gate behavior.
Product Questions and Answers
Is MA002 a control board?
No. MA002 is a 12-pin removable connector / terminal strip, not the control board itself.
What operators commonly use MA002?
It is commonly associated with LiftMaster Mega Arm and Mega Arm Tower style barrier gate operator parts lists.
Can I use any 12-pin connector?
No. The connector must match the board header spacing, orientation, and LiftMaster parts diagram.
Why would this connector need replacement?
Cracked plastic, stripped screws, corrosion, missing terminals, or damage during board replacement are common reasons.
Should wires be labeled before replacement?
Yes. Labeling wires before removal helps prevent accessory wiring mistakes.
