What Is a Hall Effect Joystick?
A Hall effect joystick employs a Hall effect sensor to monitor magnetic field changes, translating joystick movement into electronic signals.
These joysticks surpass traditional potentiometer-based models in durability and precision due to their non-contact sensing technology. They are categorized by output format (analog or digital) and the number of axes they support, which can vary from one to three.
The device operates through the interaction of four key components: a magnet, a Hall effect sensor, the joystick itself, and a control unit. The movement of the joystick alters the magnet’s position and the magnetic field, which is detected by the Hall effect sensor. The control unit then interprets these changes, converting them into the appropriate electronic output.
