UR3e

3 kg payload with infinite wrist rotation

The UR3e is the lightest, most compact, and most precise robot in the lineup. ±360° rotation on every wrist joint suits screw driving, finishing, and assembly work needing tight tolerances at a 500 mm working radius.

Maximum Payload: 3 kg (6.6 lbs)
Reach: 500 mm (19.7 in)
Max TCP speed: 3 m/s
Weight: 11.2 kg (24.7 lbs)
Footprint: ⌀ 128 mm (5.0 in)
Repeatability: ±0.03 mm

Wrist 3 Infinite Rotation
Unique to the UR3e, infinite rotation of the last wrist joint enables continuous processes, simpler programming, and higher uptime in high-cycle applications. Continuous motion: enables uninterrupted rotation for screwdriving, dispensing, polishing, and other spindle-based processes without forced stops or reversals. Higher uptime: eliminates unwind moves and reset motions, reducing cycle interruptions in repetitive, high-volume production. Simpler programming: removes joint angle limits and reduces motion complexity, making programs more intuitive and robust. Improved durability: prevents cable twisting and fatigue, extending the life of dress packs and integrated end-of-arm tooling.

Tool Connector
Integrated M8 8-pin tool connector delivers power, I/O, and communication directly at the flange – reducing cabling, simplifying integration, and enabling smarter end-effectors. M8, 8-pin female connector; EN ISO-9409-1-50-4-M6; 12 V or 24 V power supply at the tool; [2] Digital I/Os, configured as sinking or sourcing (NPN / PNP); [2] Analog inputs for sensors or [1] RS-485 communication; Safety ready architecture.
