ams OSRAM Surface Mount Position Sensor, TSSOP, Serial, 20-Pin

The ams AS5311 series is an incremental position sensor for linear and rotary off-axis applications based on contactless magnetic sensor technology. To measure position and motion a multi-pole magnet strip or ring has to be used. There are 4096 pulses per 2.0 mm pole pair length on the standardized quadrature output interface with an index pulse with a maximum speed of 650mm/s.

Contactless motion and position sensing
High speed measurement
Immune to external magnetic stray fields
