DR / DRS2 - Electrical cylinder

Ultra-compact actuator for precision motion in space-constrained designs.

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.
