The MAxxx family of position Hall-effect sensors from MPS come in many different magnetic field ranges and output formats. These robust, contactless, sensor can be used as angle encoders, suitable for control buttons and knobs. The IC detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder attached to a rotor. The output is available in SPI, SSI, PWM, ABZ and UVW. Both end-of-shaft and side-shaft sensor positions are available, all conveniently packaged in a QFN3x3-16 footprint.
