Epson LS20 SCARA Robots - 800mm

High Performance with Low Cost

Epson LS20 SCARA robots provide high performance with heavy payloads while maintaining a value price. With Epson QMEM's based Residual Vibration Reduction Technology, LS20 robots can handle heavy payloads at high speeds while competitive models have to reduce speed and accel values once any reasonable payloads are added. LS20 SCARA robots are perfect for higher payload applications such as large component pick and place, machine load/unload, palletizing, mechanical assembly, industrial part transfer and much more. When price performance is critical, Epson LS20 models deliver the high Epson Robot performance at a value price.

LS20 SCARA arms are available in 800 and 1000mm lengths with 420mm (390mm clean) Z-Axis lengths. They are also Clean ISO 4 models available. That makes for a lot of choices in the larger SCARA class of robots to make sure you get the right robot for your next application.

All Epson LS20 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+ 7.0 is also included and 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.

Epson LS20 SCARA robots handle high payloads at high speeds. They are perfect for applications requiring more reach and more payload while maintaining a lower cost. All Epson LS20 robots come with our RC90 controller which uses our 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. LS20 robots are ideal for heavy payload pick and place, packaging, machine load/unload and many more.
