DR / DRS2 Series – Compact Electric Actuators
The DR and DRS2 series combine a compact ball screw mechanism with an αSTEP AZ Series hybrid stepper motor featuring a mechanical multi-turn absolute encoder. They are ideal for precise linear motion in space-saving applications – without requiring an external feedback system.
