Automotive magnetic position sensor now shipping

Mouser Electronics is now stocking ams Osram’s AS5172E high-resolution magnetic position sensor. With AEC-Q100 Grade 1-qualified construction, the sensor offers durable performance for automotive applications including brake and gas pedals, fuel-level measurement systems, steering angle sensors and contactless potentiometers.

The sensor is designed to provide an accurate angular position measurement by determining the orthogonal component of the magnetic flux density over a full-turn rotation. Featuring a 14-bit sensor array and analog front end, the sensor uses a differential measurement method to compensate for external stray magnetic fields, ensuring accurate results through a 12-bit PSI5 output (V1.3 and V2.1) at 90deg minimum arc.

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