CAM622 ABN Board

CAM622 Test Board with ABN output for Type B Sensors

The CAM622 ABN Board generates encoder-like ABN digital quadrature signals in response to movement of a contactless target. It connects to a Type B resonant inductive sensor designed by CambridgeIC. The sensor and target are both conventional PCBs. Processing is done by CambridgeIC’s CAM622 resonant inductive encoder IC. The CAM622 energises the sensor, detects signals induced in sensor coils by the target, and processes them to determine position every 30μs. The CAM622 includes a synthesizer to generate realtime ABN signals which precisely follow target movement. A switching power supply efficiently regulates 5V power to 3.3V for the CAM622. A line driver generates differential ABN outputs. Please refer to the CAM622 datasheet for features and specifications of the CAM622, and to the appropriate sensor datasheet for sensor details and performance. A Streaming Adapter is available to connect he CAM622 ABN Board to a PC over USB. CAM622 Configuration Tool PC software is available for configuring and viewing measurement results.
