Epson offers SCARA robot systems to meet virtually every assembly and industrial process automation need. Whatever your reach and payload requirements, there's an Epson SCARA system that can satisfy them.

      • Handles payload up to 20kg
      • 800/1000mm arm length
      • Ideal for multi-effector, multi-workpiece handling


The Value Line of Epson SCARA Robots
The Epson LS-Series SCARA robots were created with reduced cost in mind. A wide variety of low cost technologies including the new RC90 controller are used with the LS-Series robots. However, the Epson LS-Series robots are still packed with the same performance and reliability our users have come to expect from Epson.

The Epson LS20 robot has an arm length of 800/1000mm in reach and cycle times down to 0.42/0.45 seconds respectively. Clean room models of the LS20 are available (ISO4) for medical, semiconductor, and other particle sensitive applications.

Outstanding cost-performance and reliability
The Epson LS-Series SCARA robots provide fast cycle times, great work envelopes, and best in class ease of use with the RC90 controller and EPSON RC+ development software.

With their small footprint and big feature set, LS Series robots are the cost-effective solution for all kinds of pick-and-place and assembly tasks. Ideal as replacements for older Cartesian units, they feature dedicated controllers for unrivaled operating ease.

*1: Cycle time based on round-tip arch motion (300mm horizontal, 25mm vertical) with 2kg payload (path coordinates optimized for maximized speed).

*2: When payload center of gravity is aligned with Joint #4; if not aligned with Joint #4, set parameters using INERTIA command.

*3: Complies with ISO Class 4 cleanroom standards.
