CambridgeIC’s CAM622 is a Resonant Inductive Encoder IC. It includes a Sensing Engine for measuring contactless position, and an Interface Processor that can generate encoder style outputs. The Sensing Engine connects to an external sensor. This detects the position of a contactless inductive resonant target. Both sensor and target are made from PCBs. They include coil patterns for resonant inductive sensing. These are available from CambridgeIC, so customers can manufacture the parts themselves and integrate them with their product. The CAM622 works with a variety of different sensor and target sizes. The Interface Processor can generate encoder style digital outputs, using an SPI interface for configuration and diagnostics. A host may alternatively use SPI as the primary interface, reading measurement results at high speed.
