Monolithic Power Systems (MPS) MagAlpha MAQ820 8-Bit Angle Encoders
Monolithic Power Systems (MPS) MagAlpha MAQ820 8-Bit Angle Encoders are designed for replace analogic potentiometers or rotary switches. These encoders feature configurable magnetic field strength thresholds, which allow for the implementation of a push or pull button function. The MAQ820 8-Bit encoders are for slow operation in Human-Machine Interfaces (HMIs) and manual controls where the rotating speed is below 200rpm. The sensor detects the absolute angular position of a permanent magnet attached to a rotating shaft and outputs incremental ABZ encoder data.
The MAQ820 8-Bit encoders are used with a diametrically magnetized cylinder with a 2mm to 8mm diameter. The on-chip Non-Volatile Memory (NVM) stores configurable parameters, such as the reference zero angle position, ABZ pulses per channel, and magnetic field detection threshold. The MAQ820 8-Bit encoders are AEC-Q100 qualified and are available in a QFN-16 (3mm x 3mm) package. Typical applications include rotary knob control interfaces, manual controls, encoders, automotive, and white goods.
