AS5147U-HTSM

AS5147U-HTSM is a 360° absolute magnetic rotary position sensor from ams (AS5147U family). It uses a Hall-effect sensor array and a magnet to determine angular position and delivers a digital angle value over a serial interface (SPI-compatible). The device provides high-resolution, wear-free absolute angle data suitable for continuous rotation applications without potentiometers. The HTSM suffix indicates the High-Temperature Small Package variant in an SMT package, designed for harsh environments and automotive/industrial use. Key features typically include: 360° angle sensing, digital output with configurable data formats, fast update rate, low power modes, and calibration options (often stored in non-volatile memory) to aid accuracy. Common applications include pedal/throttle position sensing, steering-angle sensing, rotary encoders, robotics, and other motor-control feedback tasks. For exact electrical specs (voltage, accuracy, temperature range, interface details) consult the latest AS5147U-HTSM datasheet.
