The ABB Bailey NKCL01-50 INFI-Net Cable is a precision-engineered communication cable designed specifically for ABB’s INFI-Net control network, which serves as the critical backbone of Bailey INFI 90 and Harmony Distributed Control Systems (DCS).

The NKCL01-50 model — with its 50 feet standard length — is ideally suited for medium-length interconnections between controllers, modules, and network components in industrial automation environments. Its dual-shielded construction ensures that data integrity is maintained even in environments with high electromagnetic interference (EMI) or mechanical vibration.

This cable delivers the consistent, noise-free transmission needed for high-speed, real-time process control. Whether deployed in existing ABB installations or as part of a new system rollout, the NKCL01-50 is widely trusted across industries for its reliability, durability, and ABB-certified performance.
