Magnetic sensors are solid state devices that are becoming more and more popular because they can be used in many different types of application such as sensing position, velocity or directional movement. This built-in hysteresis eliminates any oscillation of the output signal as the sensor moves in and out of the magnetic field. In linear output Hall effect sensors, as the strength of the magnetic field increases the output signal from the amplifier will also increase until it begins to saturate by the limits imposed on it by the power supply. Move the magnet at a right angle to the front of the position sensor, slowly. When magnet movement to hall sensor effect to RF (transmitter turn on) has signal to RF (receiver). Cohu offers a big variety of magnetic test solutions applying magnetic field in all three dimensions. When the device is placed within a magnetic field, the magnetic flux lines exert a force on the semiconductor material which deflects the charge carriers, electrons and holes, to either side of the semiconductor slab.
