 Capable of continuous rotation, it can be used for a variety of tasks including sonar or video scanning and vectoring thrusters. Compliance on the rotate stage can be activated to provide self protection against accidental impact. Fitted with an additional output connector the actuator is capable of passing power and signals through the rotation joint.

  • 0.1 degree position measurement.
  • Self protection (compliance feature).
  • Cable pass through available.
  • Accurate position and velocity control (RS232 full duplex).
  • 300m depth rating.
