The L12 Linear Actuator is an axial design with a powerful drivetrain and a rectangular cross section for increased rigidity.

The L12 actuator is designed to move push or pull loads along its full stroke length. The speed of travel is determined by the gearing of the actuator and the load or force the actuator is working against at a given point in time. When power is removed, the actuator stops moving and holds its position, unless the applied load exceeds the backdrive force, in which case the actuator will backdrive. Stalling the actuator under power for short periods of time (several seconds) will not damage the actuator

The linear actuator is an alternative to designing with gears, motors, servos and linkages. The controller sees the actuator as a standard RC servo.


  • 50mm stroke length
  • Maximum speed 12mm per second
  • Maximum force 23N
  • Connects to a Phidgets servo controller
  • Mounting hardware included


This actuator can be controlled by an RC servo controller. You can find a list of suitable controllers on the Connection & Compatibility tab.

Servo Controllers


This servo actuator needs to be connected to a servo controller board. If you're looking for higher torque, you should select a servo controller with an external power jack so it doesn't have to rely solely on USB power, which is limited. You can plug this servo directly to any of the boards in the list below by matching the color of the wire with the label on the board.

When controlling this device, set the speed to the maximum speed. Trying to vary the speed will produce erratic results.
