ABB Bailey NKHS03-15 Hydraulic Servo Termination Cable

The ABB Bailey NKHS03-15 Hydraulic Servo Termination Cable is a specialized, high-integrity interconnect cable designed for use with hydraulic servo valve systems, particularly within Bailey INFI 90 or Symphony DCS control architecture. This model serves a critical role in signal transmission between electro-hydraulic actuators and their respective control modules or termination interfaces.

Designed with precision shielding, high-temperature insulation, and rugged industrial-grade connectors, the NKHS03-15 ensures low-noise, interference-resistant communication—ideal for high-response servo control circuits. The 15-meter cable length provides installation flexibility while maintaining electrical performance across critical control environments such as power generation, refining, heavy machinery, and process automation.

As part of ABB Bailey’s high-reliability control cable series, the NKHS03-15 integrates seamlessly with ABB’s legacy and current generation I/O systems, guaranteeing long-term operational consistency and system compatibility.

FAQ

1. Is the NKHS03-15 compatible with third-party hydraulic servo controllers?

   Primarily designed for ABB Bailey systems, but with compatible pinouts, it may be adapted for third-party integration.

2. Can the cable be ordered in custom lengths?

   Yes, while 15 meters is the standard length, custom lengths can be ordered from ABB through authorized distributors.

3. Does the cable support analog or digital signals?

   It supports both, depending on the servo controller interface—typically analog feedback and control voltages.

4. What environments is the cable rated for?

   It is rated for high-temperature, vibration-prone, oil-contaminated, and EMI-heavy industrial environments.

5. Is re-termination possible on-site?

   Not recommended. The factory termination ensures shielding continuity and proper contact—field termination may void warranty.

6. Does ABB provide documentation or wiring diagrams with the cable?

   Yes, technical data sheets and wiring diagrams are available for authorized users and integrators.

7. Is this cable suitable for use in hazardous areas (ATEX)?

   The cable itself is not ATEX-certified but may be routed in ATEX environments if installed per local codes with proper sealing.

8. How is the cable identified in panel or junction box layouts?

   The cable features continuous external markings for part number and directionality to facilitate tracing.

9. Is the cable affected by vibration or flexing?

   It has excellent resistance to mechanical vibration, and the jacket is tested for repeated flexing cycles in control environments.

10. What is the shelf life of this cable?

    If stored in dry, UV-protected, and temperature-controlled environments, the shelf life exceeds 10 years.
