AS5048A — 14‑bit absolute magnetic rotary position sensor (encoder) Key benefits High-resolution absolute angle measurement: 14‑bit resolution (16384 distinct positions per 360°) for precise, repeatable position readout. Contactless sensing for long life: uses magnetic sensing, so there is no mechanical wear and no need for physical contact between shaft and sensor. Flexible outputs for system integration: provides digital SPI values and a PWM output representing 360° angle, making it easy to interface with microcontrollers and control electronics. Simple zeroing and setup: the sensor’s zero position can be programmed into the device with straightforward SPI commands, simplifying calibration and installation. Broad compatibility with magnet-based shaft designs: intended for shaft applications where a simple dipole magnet rotates above or below the sensor IC. Function and performance Absolute angle: measures a full 360° rotation as an absolute position, so the exact angle is available immediately after power-up. Resolution: 14‑bit angular resolution = 16384 positions per revolution returned as digital SPI values. PWM output: provides a pulse‑width modulated signal that correlates to the measured angle across 360°. Sensing principle: contactless magnetic sensor IC that reads a rotating dipole magnet; no mechanical coupling required. Compatibility and practical attributes Designed for use with a single dipole magnet placed above or below the sensor IC. Communicates via SPI for precise digital readout; PWM is available as an alternate, simple analog-compatible output. Small sensor IC format (designed as an integrated sensor chip) fits compact shaft or rotary assemblies. Reliable performance across full rotation without mechanical alignment requirements beyond magnet placement and programming of the zero position. Typical applications Robotics: joint or wheel angle measurement where precise absolute position and long service life are required. Motor control and feedback: non-contact shaft position sensing for BLDC commutation, speed control, or servo systems using simple magnet attachments. Human‑machine interfaces and rotary controls: accurate knob or dial position sensing in compact assemblies where backlash and wear are unacceptable. What it solves Eliminates mechanical wear and incremental encoder calibration by providing contactless, absolute angle feedback. Simplifies installation and recalibration with programmable zero position via SPI. Allows easy integration into digital control systems using SPI or into legacy/pulse-based systems using PWM. Model and naming AS5048A: 14‑bit absolute magnetic rotary position sensor (encoder) with SPI and PWM outputs, based on contactless magnetic sensor technology.
