Product Overview
The NVE ADT002 is an ultralow power, digital-output rotation sensor designed for precise rotational position detection. Leveraging Tunneling Magnetoresistance (TMR) technology, it offers exceptional low power consumption (1.8 A typical at 2.4 V) and a compact size, making it ideal for battery-powered applications. The sensor provides two digital, quadrature outputs that are 90 degrees out of phase, enabling directional information and accurate quadrant identification. With a wide airgap tolerance and the ability to operate with magnetic fields as low as 30 Oersteds, the ADT002 is suitable for applications such as water meters and rotational speed or position sensing.
