The EAC Series linear actuators are quick and responsive, featuring the AlphaStep AZ Series absolute mechanical stepper motor and driver, and incorporate a ball screw design, offering high performance from low speed to high speed or with light loads or heavy loads, regardless of demanding operating conditions.

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)
  • Equipped with battery-free absolute encoder
  • Positioning information can be known without a sensor
  • High reliability using closed loop control
  • Reduced motor heat and reduced energy consumption through high efficiency design
  • Connection Cables Required (sold separately*)
