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 (ABN) outputs.
The Sensing Engine connects to an external Type B Rotary Sensor. This detects the position of a contactless resonant inductive Type B Rotary Target. Type B sensors and targets 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 quadrature digital outputs with reference pulse ("ABN"). The CAM622's True Edge Timing ensures that ABN edges emulate those generated by an ideal optical encoder. The ABN interface is fully programmable over SPI, and the CAM622 includes non-volatile memory to store its configuration for standalone operation. CambridgeIC's Streaming Adapter may be used for programming. It connects between the CAM622's SPI and a PC's USB port. A CAM622 Configuration Tool is available to run on a PC.
A host may alternatively use SPI as the primary interface, reading measurement results over SPI at high speed.
A CAM622 ABN Board is available for customer evaluation and prototyping.
