Description
🔹 Product Introduction
The ABB 128877-103 is identified in parts catalogs as a SP1200 IR Detector Cable, rather than a PC board. It is an interconnection component associated with ABB SP1200 infrared detection equipment and is used to carry signals between compatible detector components and the related system hardware.
When replacing this part, verify the complete part number, cable connectors, length, and equipment configuration. The model number alone does not establish compatibility with other ABB detector or automation systems.

🔧 Fault Troubleshooting and Common Questions
- Detector signal is missing: Inspect cable connections, connector pins, and the cable jacket for damage.
- Intermittent detector readings: Check for loose connectors, broken conductors, or contamination at the connection points.
- Can another cable replace it? Only if the connector type, pinout, length, and electrical requirements match the original specification.
- Is this a PC board? Available catalog information identifies 128877-103 as an infrared detector cable. Confirm the physical item and label if the listing describes it as a PC board.
⚠️ Safety Precautions
Switch off and isolate the associated equipment before disconnecting the cable. Follow the manufacturer’s service procedure, avoid pulling on the conductors, and ensure that connectors are fully seated before returning the system to service.
