The NVE ADT002-10E rotation sensors are ultralow power, digital-output magnetic rotation sensors. Tunnelling Magnetoresistance (TMR) technology allows small size and extremely low power of 1.8µA (typ.) at 2.4V, making the sensors ideal for battery operation. The ADT002-10E sensor has two digital, binary outputs which are 90° out of phase to provide directional information. This sensor also operates with a magnetic field as little as 30Oe with an additional output which indicates a fault if the magnetic field is too high for accurate measurements.
