NVE AA002-02E

NVE's analog GMR sensors have high sensitivity, excellent temperature stability, and small size. Their versatility and wide sensing range makes them an excellent choice for a variety of analog sensing applications including industrial and automotive position, speed, and current sensors. The sensors are configured as inherently temperature - compensating Wheatstone bridges. AA - Series sensors are magnetometers, which detect absolute magnetic field. AB - Series sensors are differential gradiometers, which detect field gradients. Three magnetometer subtypes are available: the standard AA - Series; the ultrasensitive "H" subtype; the high - field, kiloersted range "K" subtype, and the low - hysteresis "L" subtype. Packages are as small as an ultraminiature 1.1 × 1.1 mm ULLGA4.
