ABB IRB 6600/6650 Series: Comprehensive Robot Cable Harness Range and Technical Overview

The ABB IRB 6600 and IRB 6650 series are high-payload industrial robot platforms deployed across heavy-industry sectors including automotive body-in-white assembly, foundry operations, chemical processing facilities, nuclear decommissioning cells, and petroleum refinery material handling. With payload ratings from 125 kg to 235 kg and reaches up to 2.55 m, these manipulators represent ABB's mature 6-axis architecture for floor-, wall-, and inverted-mount configurations. The internal cable harness system — routed through the manipulator base, lower arm, and upper arm — is a critical maintenance item with defined replacement intervals under ABB's Preventive Maintenance schedule. Part numbers in the CR82350010, CR82350042, and 3HAC prefix families are the primary OEM references for this harness assembly.

The Evolution of IRB 6600/6650 Cable Harness Architecture

The IRB 6600 platform was introduced in the early 2000s as a successor to the IRB 6400 series, inheriting the S4C+ controller ecosystem before transitioning to the IRC5 controller cabinet. The internal cable harness architecture evolved across three distinct generations:

Generation 1 (S4C+ era, ~2001–2005): Harnesses used discrete multi-pin Burndy-style connectors with separate power and signal looms. Replacement required full loom extraction from the base casting. Cross-reference prefix: CR82350010 / B36D4P-07028.

Generation 2 (IRC5 transition, ~2005–2012): ABB consolidated signal and power routing into a unified harness assembly for axes 1–4, reducing connector count and improving MTTR. The 3HAC16331-1 assembly is the primary OEM part number for this generation, covering manipulator axes 1 through 4 as a single replaceable unit. Cross-reference: CR82350042 / B6305Q-02454.

Generation 3 / Current (IRC5 with SafeMove, ~2012–present): Harnesses incorporate additional shielded conductors for SafeMove2 encoder feedback and dual-channel brake circuits. Backward compatibility with Gen 2 mounting points is maintained, but connector pinouts differ. Operators running mixed fleets must verify harness revision codes before substitution.

Sealing & Protective Components

• 3HAC028352-001: Cable entry gland kit, IP67; used at base cable entry point during harness replacement to restore ingress protection rating.
• 3HAC16332-1: Cable clamp set, axes 1–4 harness routing; includes all nylon saddle clamps and stainless fasteners specified in ABB service manual section 4.3.
• 3HAC025339-001: Protective conduit sleeve, lower arm; replaces outer sheath on harness routing channel; required when original sleeve shows abrasion damage.

Quality Control for the IRB 6600/6650 Cable Harness Range

Cable harness assemblies for the IRB 6600/6650 series undergo a structured inspection and test protocol before dispatch:

• Visual inspection: Full loom examination for jacket abrasion, connector pin corrosion, and strain relief integrity at all termination points.
• Continuity test: 100% conductor-by-conductor continuity verification against ABB wiring diagram 3HAC16331-1 Rev. C (or applicable revision).
• Insulation resistance test: 500 VDC megger test between all conductors and shield; minimum acceptance threshold 100 MΩ.
• Connector mating test: All M23, Burndy, and JST connectors mated and de-mated 5 cycles to verify locking mechanism and contact retention force.
• Shield continuity: Drain wire and braid shield continuity verified end-to-end; critical for SafeMove encoder feedback integrity.
• Documentation: Each assembly ships with a test record, part number label, and country-of-origin certificate.
