描述
The RAA2P4200 is a magnet-free, inductive position sensor IC designed for absolute rotary, linear, or arc position sensing in industrial applications. It operates on the principle of eddy currents, detecting the position of a simple metallic target that is moving above a set of coils, comprising one transmitter coil and two receiver coils.
Inductive sensing technology offers significant advantages over magnetic technology, including greater flexibility, easier system integration, and enhanced performance, reliability, and cost efficiency. As a result, it is becoming the preferred choice for a wide range of industrial applications.
