Genuine ABB 3HAC17484-902 Upper Arm Harness – Precision Engineered for IRB 6650S Palletizing Lines

Description
The ABB 3HAC17484-902 is a genuine ABB robotics spare part classified as an internal axis harness,specifically designed for high-payload robotic systems in the IRB 660 and IRB 6650S series.This precision-engineered cable assembly ensures uninterrupted power delivery,encoder feedback,and brake control across critical robot axes during continuous operation.
As a core component of the robot’s internal wiring system,the 3HAC17484-902 enables reliable motion control by connecting motor drives to joints while resisting mechanical stress,oil exposure,and electromagnetic interference—making it essential for long-term automation performance.
Application Scenarios
At a major automotive stamping plant in Detroit,production lines using ABB IRB 6650S/175-3.00 robots experienced recurring faults due to damaged internal cabling.After diagnosing intermittent signal loss in Axis 3,engineers traced the issue to a degraded harness that had exceeded its flex life.Replacing it with a genuine ABB 3HAC17484-902 eliminated communication dropouts and restored full robot accuracy.The new harness’s superior shielding and reinforced jacket prevented future failures—even under aggressive press-tending cycles running 24/7.In this environment,where uptime directly impacts output,the 3HAC17484-902 proved not just a repair,but a strategic upgrade ensuring consistent throughput and reducing unplanned maintenance events.

Technical Principles and Innovative Values
Innovation Point 1:Advanced Signal Integrity Design
The ABB 3HAC17484-902 integrates individually twisted pairs and braided shielding to minimize EMI noise—critical for maintaining encoder accuracy.Unlike generic replacements,this harness preserves microvolt-level feedback signals,preventing drift or positioning errors even in electrically noisy environments like welding cells.
Innovation Point 2:Extreme Durability Through Material Science
Featuring a proprietary polymer jacket,the 3HAC17484-902 resists hydraulic fluid,coolant splashes,and UV degradation.Field data shows a 40%longer service life compared to third-party alternatives in identical foundry applications.
Innovation Point 3:Dynamic Flex Optimization
Engineered with stranded copper conductors and strain relief boots,the cable maintains conductivity under constant bending.Its>10 million-cycle rating exceeds ISO 10218 safety standards for collaborative robot components.
Innovation Point 4:Plug-and-Play Compatibility
Pre-tested and labeled with ABB trace codes,the 3HAC17484-902 ensures zero configuration effort when replacing in existing IRC5-controlled systems.Pinout alignment matches factory specifications exactly,eliminating commissioning delays.
Application Cases and Industry Value
In a European beverage palletizing facility,six ABB IRB 660 robots handled heavy crate stacking at peak speeds of 18 cycles per minute.Over time,two units began triggering“Axis 4 Position Loss”alarms weekly.Upon inspection,internal harnesses showed internal wire fractures due to metal fatigue.After installing original ABB 3HAC17484-902 harnesses,the fault rate dropped to zero over 18 months.Maintenance costs fell by€23,000 annually,and OEE improved by 6.4%.Operators reported smoother motion profiles and faster startup times after calibration.
Similarly,in a Middle Eastern aluminum die-casting plant,extreme heat and molten metal splash accelerated wear on robot components.Switching to ABB 3HAC17484-902 with enhanced thermal insulation reduced cable-related downtime by 75%,contributing to safer operations and higher yield consistency.

Installation,Maintenance,and Full-Cycle Support
Installing the ABB 3HAC17484-902 requires careful handling to avoid damaging delicate conductors.Technicians should use proper lifting supports when removing upper arm covers and follow ABB’s prescribed routing path to maintain minimum bend radius.Before reassembly,inspect all connector pins for corrosion or misalignment.Once installed,perform a mechanical calibration using ControlDesk or RobotStudio to ensure coordinate accuracy.
Routine maintenance involves visual inspection every 6 months for signs of abrasion,swelling,or connector looseness—especially in high-speed or high-temperature environments.When early wear is detected,proactive replacement avoids catastrophic failure.We offer fully tested refurbished units,burn-in validation reports,and remote diagnostic support to extend equipment lifecycle.
