MA702GQ-P

MA702GQ-P is a 12bit, digital, contactless angle sensor with ABZ incremental & PWM outputs. It detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. Fast data acquisition and processing provide accurate angle measurement at speeds from 0 to 60,000rpm. The MA702 supports a wide range of magnetic field strengths and spatial configurations. Both end-of-shaft and off-axis (side-shaft mounting) configurations are supported. It features magnetic field strength detection with programmable thresholds to allow sensing of the magnet position relative to the sensor for creation of functions such as the sensing of axial movements or for diagnostics. The application includes general purpose angle measurement, angle encoders, automotive angle or speed sensors, robotics.
