Torque 50 to 200 Nm
60° stroke
Absolute position control
Several communication protocols

Do you have a submersible equipment project?

The XAR-A range of subsea rotary actuators from LF Technologies are submersible electric rotary actuators specially developed for subsea applications.
Thanks to their radial output and hollow through shaft, these actuators are particularly well suited to high-torque control surface manoeuvres over limited travels and can be mounted directly around the manoeuvring shaft. Their high dynamics ensure rapid changes of direction.

Features of the XAR-A underwater rotary actuator :

Integrated control: on-board electronics for precise control of position and speed directly in the actuator.
Absolute position measurement: integrated absolute position measurement: no need to search for zero.
Multiple communication protocols: compatible with several protocols such as CAN, RS232, Ethernet TCP, Ethernet UDP, Modbus TCP, with customisation on request.
Flexible mounting: a range of mounting and drive options for easy mechanical integration into a variety of subsea systems.
Daisy-chaining: each actuator is fitted with 2 connectors (1 In and 1 Out) enabling several actuators to be daisy-chained to limit the amount of wiring required on your system.

Validation and testing of XAR-A underwater rotary actuators

All submarine rotary actuators developed by LF Technologies are fully tested in-house:

Full functional tests: tests carried out in air and in immersion under real load;
Rigorous tightness tests: validation of tightness up to maximum permissible pressure.
Verification of communication protocols: checks that the protocol chosen by the customer is operating correctly (CAN, RS232, Ethernet TCP, Ethernet UDP, Modbus TCP, protocols on request).
Full energy analysis: measurement of current and power consumption according to several usage scenarios.
