Product Information

Back to top
iC-MP consists of a quadruple Hall sensor array which has been optimized for the magnetic measurement of an axis angle. The array permits error tolerant adjustment of the magnet, reducing the time and effort required assembly. The integrated signal conditioning unit provides a differential sine/cosine signal at its outputs. The sensor generates one sine cycle per full rotation of the magnet, enabling the angle to be clearly determined. At the same time the internal amplitude control unit produces a regulated output amplitude of 2 Vpp, regardless of variations in the magnetic ?eld strength, supply voltage and temperature. Furthermore, error signals are provided which report any magnet loss and an excessively high RPM speed.
