ABB 3HAC11440-1 Manipulator Harness Axes 5-6 for IRB 7600 Robot

Manipulator Cable Harness for ABB IRB 7600 Axes 5-6

Specifications

Industrial Applications

• Carries axis-5 and axis-6 motor power and encoder feedback inside the IRB 7600 upper arm.
• Routes the signal path from the upper-arm division point to both wrist motors.
• Service replacement of a degraded, abraded or connector-damaged wrist-axis harness.
• Used in foundry, welding and heavy-material-handling cells where the IRB 7600 runs in high-cycle or high-temperature duty.

Design Purpose

The wrist axes 5 and 6 sit at the end of a long, constantly moving upper arm. Running each conductor back to the cabinet separately would create a thick, stiff and failure-prone loom. ABB instead routes the power and feedback for both wrist motors through one defined harness path — out from the division point R2.M5/6 to the axis-5 connectors R3.FB5 / R3.MP5 and the axis-6 connectors R3.FB6 / R3.MP6. This keeps the wrist flexible and makes the wiring serviceable as a single assembly rather than a nest of loose cables.

That is also why the harness is revision-specific. Its length, connector set and clamp positions are tied to the exact upper-arm version and robot variant. Mechanical similarity between two robots does not make their harnesses interchangeable — the documented article number, robot variant and harness revision must match. This is therefore a confirmed-fitment spare, not a generic cable you cut to length.

Common Failure Modes

• Insulation fatigue or jacket cracking from repeated wrist flexion in high-cycle duty.
• Connector oxidation or pin corrosion from foundry particulate, humidity or washdown.
• Abrasion where the loom rubs the upper-arm heat plate or clamps.
• Intermittent axis-5 / axis-6 feedback or motor-power faults from a damaged conductor.
• Misrouted excess cable causing tension or jamming through wrist travel.
• Loss of revolution-counter or calibration data if the SMB battery is disconnected without a prior backup.

Why Choose Us

• Genuine ABB 3HAC11440-1 IRB 7600 axes 5-6 manipulator harness — the upper-arm cable assembly, not a generic cable.
• Fitment confirmation: we verify your robot serial, variant and harness revision from the label and ABB spare-parts table so you receive the correct wrist branch (R2.M5/6 to R3.FB5/MP5, R3.FB6/MP6).
• Foundry Plus advisory: we flag gasket 3HAC033489-001 so the service scope is complete.
• Condition confirmed before ordering (new original or used original); quotation-based supply with no stock or dispatch-time promises.

Related Products

• 3HAC031851-001 — ABB SMB-unit DSQC633A (serial measurement board on the robot). Confirmed for the IRB 7600 family; relevant because harness service can disconnect its battery and trigger a revolution-counter update — plan calibration afterwards.
• 3HAC033489-001 — ABB Foundry Plus sealing gasket, recommended during this harness's service on Foundry Plus robots. Listed so the service scope is complete.
• 3HAC14139-1 — ABB IRB 7600 axis-5 single-branch harness. This is the axis-5-only branch, not the 5-6 assembly in 3HAC11440-1 — confirm which branch your robot needs before ordering.
