ams OSRAM AS5172E automotive magnetic position sensor

The ams OSRAM AS5172E high-resolution magnetic position sensor provides angular position measurement by determining the orthogonal component of the magnetic flux density over a full-turn rotation.

With AEC-Q100 Grade 1-qualified construction, the sensor offers durable performance for automotive applications including brake and accelerator pedals, fuel-level measurement systems, steering angle sensors and contactless potentiometers. Featuring a 14-bit sensor array and analog front end, the product uses a differential measurement method to compensate for external stray magnetic fields, providing results through a 12-bit PSI5 output (V1.3 and V2.1) at 90° minimum arc.

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