Summary of AMS AS5116-HSOT ON-AXIS MAGNETIC POSITION SENSOR
AMS AS5116-HSOT is a contactless on-axis magnetic position sensor that provides accurate 360° angular measurement using Hall sensor technology to detect the orthogonal flux component (Bz). A two-pole magnet rotates over the package center (above or below) and the device outputs buffered differential sine and cosine analog voltages. It offers high precision, low noise, robustness, and automotive qualification, operates from -40°C to 150°C with 3.3V or 5V supply, and suits motor rotor sensing, EPS, pumps, transmission actuators, and starter/generator systems.

ams AS5116-HSOT On-Axis Magnetic Position Sensor is a contactless sensor for accurate angular measurement over a full mechanical turn of 360°. This sensor features a robust architecture based on Hall sensor technology that measures the orthogonal component of the flux density (Bz) over a full-turn rotation. The AS5116-HSOT magnetic position sensor uses a simple two-pole magnet rotating over the center of the package to measure the angle. This magnet can be placed above or below the device and the absolute angle measurement provides an instant indication of the magnet’s angular position. The angle information is provided by means of buffered differential sine and cosine voltages. This sensor offers the highest reliability, durability, low output noise, and high precision analog output. The AS5116-HSOT magnetic position sensor operates at the -40°C to 150°C temperature range and requires a supply voltage of 3.3V or 5V. Typical applications include rotor angle sensing of electric commutated motors, electric power steering systems, electric pumps, actuators in transmission systems, and starter/generator systems.
