Overview Direct Angle Sensors
New types of Hall-effect sensors do not measure the absolute magnetic field anymore. So-called direct angle sensors capture the field vector by measuring sine and cosine components of the magnetic field. This is possible due to the new 3D HAL technology from TDK-Micronas. Vertical Hall plates measure the magnetic field components in the chip plane and not the components perpendicular to the chip surface . These kind of sensors provide angular and position information directly via an output signal proportional to the measured angle or position.
