Epson LS3 SCARA Robots - 400mm

High Performance with Low Cost

  • Fast Cycle Throughput
  • Industry Leading Ease of Use
  • 400mm Arm Length
  • ISO 4 Clean Model Available

Epson LS3 SCARA robots are perfect for factories looking for maximum value without giving up performance. They are used for applications such as mechanical or electrical assembly, pick and place, kitting, dispensing and much more. Epson LS3 SCARA's are the robot of choice when price/performance is critical. LS3 SCARA arms come with a 400mm arm length and ISO 4 Clean models are available. With outstanding cycle times, industry leading ease of use and of course Epson reliability, LS3's are the robots of choice.

All Epson LS3 SCARA Robots are available with our low cost, high performance RC90 Controller that provides the ultimate experience in ease of use and reliability all at an incredibly low price. Epson RC+ is the development environment of choice for reducing overall development time with powerful tools and easy to use integrated options such as Vision Guidance , DeviceNet, Profibus, Microsoft .NET support, GUI Builder and much more.

As part of our LS-Series robot lineup, the LS6 models are perfect when more reach or payload is required for applications which require high speed but at a lower cost. The LS6 robots come with our RC90 controller which uses the Industry leading RC+ Development Environment and has a host of options available including vision guidance, .NET connectivity, DeviceNet, Profibus, CC-Link, GUI Builder and much more. LS6 robots are ideal for pick and place and simplistic applications although the RC90 has the power to handle more complex applications as well.
