ABB DSQC352B 3HAC031683-004 3HAC024385-001 – Manipulator Harness Axis 1–6 | ABB IRB Robot Series
The ABB DSQC352B (also referenced as 226429, 3HAC031683-004, and 3HAC024385-001) is the OEM-specified internal manipulator harness for ABB IRB-series industrial robots, routing power, signal, and feedback wiring through axes 1 through 6. Procurement engineers sourcing this harness require exact cross-reference accuracy — a single incorrect cable assembly can ground an entire production cell. Konmask.com stocks verified, traceable units to eliminate that risk.
Product Positioning: This harness is a safety-critical, motion-path component. It is not interchangeable with generic cable assemblies. Only OEM-equivalent units with correct connector pinouts, shielding topology, and bend-radius ratings should be installed in ABB IRB manipulators.

Proven Application Environments
- Automotive body-in-white welding and assembly lines
- Foundry and die-casting robot arms (high-cycle, high-temperature ambient)
- Palletizing and material-handling IRB 4400 / IRB 6600 / IRB 6640 cells
- Painting and coating robots requiring EMI-shielded signal integrity
- Semiconductor and electronics assembly (cleanroom-compatible variants)
- Preventive maintenance replacement programs (scheduled harness swap at OEM intervals)
Engineering Advantages
- Full Axis Coverage: Single harness routes all six axes — eliminates multi-segment splice points and associated failure modes.
- OEM Connector Pinout: Exact match to ABB IRC5 / S4C+ controller wiring diagrams — no field modification required.
- Continuous-Flex Rated: Designed for millions of flex cycles at rated robot speed — not a static-installation cable repurposed for robotics.
- EMI Shielding: Dual-layer shielding suppresses encoder feedback noise, critical for high-precision path accuracy.
- Traceable Lot: Each unit supplied with batch traceability documentation on request.
System Architecture & Signal Flow
The DSQC352B harness originates at the robot base (Axis 1 drive / IRC5 cabinet interface) and routes internally through the manipulator structure to the wrist (Axis 6). It carries:
- Motor Power Conductors: 3-phase power to each axis servo motor
- Resolver / Encoder Feedback: Position feedback signals for all six axes
- Brake Control Signals: Axis holding brake engage/release lines
- Thermal Sensor Wiring: Motor winding temperature monitoring (PTC/NTC)
- Safety Interlock Lines: Emergency stop and safety relay circuits
Signal integrity across all conductors is maintained by the dual-shield topology, ensuring the IRC5 motion controller receives clean feedback even in high-EMI welding environments.
Sourcing & Quality Verification
- Units sourced from ABB-authorized distributors and certified surplus channels
- Each harness inspected: connector integrity, insulation resistance, continuity across all conductors
- Packaging: anti-static bag + rigid outer carton, coiled to OEM bend-radius specification
- Lot traceability documentation available upon request (batch number, inspection date)
- 12-month warranty against manufacturing defects

Technical FAQ
Q: Are DSQC352B, 3HAC031683-004, and 3HAC024385-001 the same part?
A: Yes. These are ABB’s cross-reference part numbers for the same manipulator harness assembly. 226429 is the legacy catalog number. All refer to the identical physical component.
Q: Which IRB robot models use this harness?
A: The DSQC352B is used across multiple ABB IRB series models. Please provide your robot model and serial number for definitive confirmation before ordering.
Q: Can this harness be repaired rather than replaced?
A: ABB does not recommend field repair of internal harnesses due to continuous-flex and EMI-shielding requirements. Full replacement is the OEM-specified corrective action.
Q: Is the harness compatible with both IRC5 and S4C+ controllers?
A: Compatibility depends on the specific robot model and controller revision. Confirm with your robot serial number and controller software version.
Q: Do you provide installation support?
A: We provide the OEM wiring diagram reference and connector pinout documentation. On-site installation support is available through our partner network — contact us for details.
