High-resolution automotive magnetic position sensor provides durable performance

11-05-2022 | Mouser Electronics | Automotive Technologies

Mouser now stocks the ams OSRAM AS5172E high-resolution magnetic position sensor. With AEC-Q100 Grade 1-qualified construction, the magnetic position sensor provides durable performance for automotive applications, including fuel-level measurement systems, brake and gas pedals, steering angle sensors, and contactless potentiometers.


The sensor offers a highly accurate angular position measurement by determining the orthogonal component of the magnetic flux density across a full-turn rotation. Providing a 14-bit sensor array and analog front end, the sensor utilises a differential measurement method to compensate for external stray magnetic fields, providing accurate results through a 12-bit PSI5 output (V1.3 and V2.1) at 90 degrees minimum arc.


The highly durable sensor supports an extended operating temperature range of -40C to 125C and a supply voltage of up to 16.5V, with overvoltage protection to 20V and reverse polarity protection to‑18V.
