Function

The tab position sensor measures the exact position of the trim tab or control tab mechanism and sends that information to the boat’s control electronics.

It helps the system to:

• Monitor tab angle and position

• Provide feedback for automatic trim control

• Support joystick docking and steering adjustments

• Maintain optimal handling and vessel stability

Without accurate sensor feedback, the control system cannot correctly determine tab position.
