αSTEP Closed Loop AZ Series Absolute Encoder Hollow Rotary Actuators

The DGII Series is a line of of products that combine a high rigidity hollow rotary table with an αSTEP absolute encoder AZ series closed loop stepper motor and driver package. It retains the ease of use of a stepper motor, while also allowing for highly accurate positioning of large inertia loads.

Integrated actuator and stepper motor makes design easier
Vertical or Horizontal Mount Motor Types
Easy Home Setting and Return-to-Home without need for sensors
Large-diameter hollow output table
AC or DC Input
