ams' AS5510 is an absolute position sensor for linear applications with short strokes (0.5 mm to 2 mm) based on contactless magnetic sensor technology. To measure a lateral movement the sensor needs a simple 2-pole magnet and the measured distance depends on the magnet geometry. The absolute position is measured with a resolution of 10-bit = 1024 positions and it is provided as a digital value on the serial interface (I²C).
