Broad range of features

  • A wide range of operating speeds and closing times.
  • Most versions available for both open/close and modulating service.
  • Watertight enclosures.
  • Double-seal terminal compartment is an option
  • Conventional actuator version (with limit and torque switches) featuring easy to set end-of-position switches.
  • Non-intrusive actuators with reliable absolute encoders and microprocessor-based AC AUMATIC controls.

Actuator controls

Actuators with integral controls are provided by means of AUMA’s control options - the AM AUMA Matic and AC AUMATIC.
