The EAS Series linear actuators offer high performance, from low speed to high speed or with light loads or heavy loads, regardless of demanding operating conditions. These motorized linear slides, with the AlphaStep AR Series motor and driver, are quick and responsive and incorporates a ball screw and a THK-manufactured LM Guide™ as the guide. Being compact and rigid, this series is effective in supporting large transportable mass. The built-in controller (stored data) allows for easy networking and simplified multi-axis control.
  • Controller connection options: 1: I/O, 2: Modbus (RTU/RS-485) or 3: FA Network (network converter)
  • Reversed Motor (Right Side) Type
  • X-axis Table
