Epson G3 SCARA Robots

250 | 300 | 350

  • Best in Class Cycle Time and Precision
  • Tabletop, Ceiling and Wall Mount Models
  • Unique Curved Arm Option
  • ISO Clean & ESD Compliant Models

Epson G3 robots lead the industry with best in class cycle time, precision and motion range. With over 30 models available in sizes from 250-300mm, EPSON G3 robots are the robot of choice for high precision, high speed applications where performance AND low cost are required. G3 SCARA robots are ideal for applications such as hard drive assembly, lab automation, electronics assembly, medical device assembly, photonics, semiconductor, telecommunications, solar, and many others.

Unique to the G-Series, is the new curved arm option which allows G3 arms to be purchased as right or left curved models to maximize work envelope usage while maintaining small workspace usage overall. G3 arms are available in 250, 300 and 350mm arm lengths and come with 150mm (120 clean) Z-Axis lengths. They are also available in table top, wall or ceiling mount configurations as well as Clean/ESD configurations. Lots of choices. A lot more Power of Choice.

Epson G3 SCARA Robots

Features & Benefits

EPSON created the compact class of SCARA robots over 10 years ago with our E-Series line. Now 2 generations later our G3 SCARA arms continue to lead the industry in the compact SCARA market. While small in size, the G3 arms incorporate all the same high peformance components and design concepts as the other G-Series robots such as high rigidity arms as well as our PowerDrive servo technology to yield high performance results in a compact and lower cost format.

High Performance

  • Best in Class Motion Range with maximum footprint efficiency
  • Champion Cycle times of 0.41 seconds improve total part throughput
  • Outstanding Accel/Decel Rates with smooth start/stop motion
  • Top speeds of almost 4400 mm/sec gets parts moved fast and precisely
  • Low residual vibration due to unique high rigidity arm design
  • High duty cycle allows fast cycles 24/7

Wide Variety of Arms and Configurations

  • Arm lengths of 250, 300 and 350mm provide customers the ability to choose the best arm for the job (no one size fits all philosophy here)
  • Tabletop and multi-mount (ceiling/wall mount) Models
  • ISO Clean & ESD Compliant Models for semiconductor and static sensitive applications like hard drive assembly
  • Unique Right or Left handed curved arm models are available to maximize work envelope usage

Best in Class Controllers and Development Software

  • Epson RC+ leads the industry in ease of use to save development time
  • Two tiered controller offerings allow high performance or low cost solutions with G3 robots
  • Integrated options to maximize system performance and reduce overall development time (see options page for more details)
