Ten-bit linear position sensors with digital position output

Based on contactless magnetic sensor technology, the ams AS5510 absolute position sensor for linear applications with short strokes (0.5mm to 2mm), is now available from Digi-Key. 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).
