Hall technology is based on a well-known physical effect: if you apply a voltage to an electrical conductor, an electrical current flows. The electrons move through this conductor. If this conductor is now held in a stationary, homogeneous magnetic field, the so-called Lorentz force acts on the electrons. This causes the electrons to be deflected perpendicular to the movement and, similar to a capacitor, a charge separation takes place. The opposing positive and negative charge carriers create an electric field and thus a voltage - the so-called Hall voltage. This voltage is linear to the strength of the magnetic field and is therefore ideally suited for mapping changes in position. The Hall sensor records this in the form of voltage changes.
Our Metallux.de Hall rotary sensors (image) and Hall joysticks stand for wear-free operation and are built into robust housings. We offer our customers numerous standard and individual special solutions.
