Electro-mechanical part-turn actuator

The compact actuator, classic technology, robust, reliable for cost-sensitive applications up to 60 Nm

The actuator drive series Nano has been designed for industrial use. A robust aluminum housing combined with the impact resistant plastic cover reliably protects the drive technology even in harsh environments. Weight savings through the use of a plastic hood in combination with the compact design allow you to use them even on small actuators / fittings. The consistently cost-optimized design in combination with a high quality allows the use in cost-sensitive systems without compromising reliability.

Of course, the Nano is available in all standard voltages (230 V, 115 V, 24 V AC, or 12 V DC).


Synchronous motor technology (AC) or direct current motor (DC)

  • The permanent magnets built into the synchronous motor ensure a high holding torque even in a de-energized condition (AC)
  • The motor speed depends solely on the voltage frequency. Therefore a constant and load-free actuating time is ensured.

Mechanical data
Robust aluminum body

  • For use in harsh industrial environments, high operational safety.
  • Reinforced cover protects reliably all functional parts and serves as optimal isolation of the electric components; high operational safety.

Classic shut-off system via switching cams and micro switches

  • No voltage supply necessary for position indication and shut-off. Nano actuators are 100% connection compatible to ARIS actuators sold before 2014; perfectly suitable as exchange actuators.
  • Tool-free adjustable aluminum switching cams allow a fast and exact actuator setup.


  • Optional potentiometer allows a permanent feedback of the current actuator position.
  • The potentiometer self-adjusts automatically to the path after setup via an integrated friction clutch.
  • Several types allow an ideal utilization of the full potentiometer range:
  • Nano S 90°/180°/320°, Nano M 30…40 Nm 10°…150°, Nano M 50…60 Nm 10°…100°.
