Renesas Electronics RAA2P3200 Low-Latency Inductive Position Sensor

Renesas Electronics RAA2P3200 Low-Latency Inductive Position Sensor can be used for absolute rotary, linear, or arc position sensing applications targeting all industrial applications. The Renesas Electronics RAA2P3200 operates on the principle of Eddy currents to detect the position of a simple metallic target moving above a set of coils, comprising one transmitter coil and two receiver coils. Inductive sensing technology is expected to replace magnetic technology in various applications by providing much higher accuracy, flexibility, easy integration into system solutions, and improvements in performance, reliability, and cost.
