CAM312

CAM312 EnhancedImage h75The CAM312 is a single-chip non-contact position sensor IC for resonant inductive position sensing. It can connect to and process up to two sensors and report results to a host over a single SPI interface.

Development boards are also available to help you understand CAM312 performance. Find out more here
