Product Introduction
The ABB DSTK150 (26390603-A) is a specialized ribbon cable assembly designed for internal interconnection within Bailey INFI 90 and ABB robot control systems. It serves as the critical physical link that routes signals between circuit boards and the system backplane.This flat ribbon cable ensures reliable data transmission and power distribution within the control module. Weighing approximately 1 kg, it is engineered to fit precisely within standard industrial control enclosures. (Always verify the exact OEM part number 26390603-A on your existing cable, as ribbon cables are highly specific to connector pinouts and wire counts).
Installation & Configuration Guide
Preparation
Ensure the control chassis is completely de-energized and locked out. Gather appropriate screwdrivers and an ESD wrist strap. Document the routing path and orientation of the existing cable before removal.Removal (5–10 min)
Carefully disconnect the ribbon cable from both ends. Release any retaining clips or connectors gently to avoid damaging the fragile pins. Remove the DSTK150 from the enclosure, noting how it is routed and secured.Installation (10 min)
Route the new DSTK150 exactly as the original, avoiding sharp bends or pinch points. Align the connector keys precisely before seating. Press firmly and evenly until all connectors lock into place. Secure any cable ties or retention clips.Power-On & Test
Restore power to the system. Monitor the module status LEDs for normal operation. Verify that all signals routed through this cable are communicating correctly. Check for any intermittent faults that could indicate a misaligned connector.
Troubleshooting Quick Reference
- Module not communicating: Reseat both ends of the DSTK150. Check for bent pins on the connector. Verify the cable is not pinched or damaged.
- Intermittent signal loss: Inspect the cable for cracks, creases, or worn insulation. Ensure the cable is not routed near high-voltage lines or heat sources.
- Multiple I/O failures: This cable may carry multiple signal lines. A single connector issue can affect many channels. Reseat and inspect both connectors thoroughly.
- No power to sub-module: Verify the power pins on the ribbon connector are making proper contact. Check for blown fuses on the source board.
- Cable too short/tight: Do not force or stretch the DSTK150. Re-route or verify you have the correct OEM length.
Dimensions, Mounting & Wiring Notes
- Size: Custom ribbon length; verify against OEM 26390603-A specification
- Mounting: Internal routing with retention clips or cable ties; avoid sharp bends (min bend radius applies)
- Wiring: Keyed connectors for proper orientation. Do not force connectors; they are designed to mate only one way.
FAQ
Is this the same as part number 26390603-A?
Yes. DSTK150 is the commercial designation, and 26390603-A is the OEM part number. Always cross-reference both to ensure compatibility.Can I use a generic ribbon cable instead?
No. The DSTK150 has specific wire counts, pinouts, and connector types. A generic cable will likely not match the connector keying or signal routing.My cable looks fine but signals are failing. What now?
Internal wire breaks can occur without visible damage. Reseat the connectors first. If the issue persists, replace the DSTK150 as a diagnostic step.Do you test these cables before shipping?
Yes. Each DSTK150 undergoes continuity testing on every wire and connector pin verification to ensure no open circuits or shorts exist.Can I repair a damaged ribbon cable?
Not recommended. Ribbon cables are not field-repairable. Replace the entire DSTK150 assembly to maintain system reliability.How do I know if I need this exact cable?
Check the OEM part number printed on the existing cable or in your system’s hardware manual. Even minor revisions can have different pinouts.
