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 temperaturecompensating 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,kilooersted range “K” subtype, and the low-hysteresis “L” subtype. Packages are as small as an ultraminiature 1.1 x 1.1 mm ULLGA4.
