Duplex Rotary Actuator

Duplex actuator mainly used for throttle actuation. The actuator is designed with system redundancy whereby the drive train and positional feedback are duplicated within the actuator. Should the actuator experience system failure on one channel there is a second channel that assumes control, sensors work in unison to ensure no loss of positional data. The actuator does not backdrive.



  • Positional feedback accuracy – 0.2°
  • Operating Torque – 10Nm
  • Response rate – 45° per second
  • Actuator weight – 3.5kg

Case Study

The simplex version of this actuator is used for wheel braking functions.
