AA and AB-Series Analog Sensors

NVE offers two types of analog magnetic sensors: magnetometers, which measure magnetic field strength; and gradiometers, which measure the change, or gradient, in field strength over a distance. Popular part types are listed below (click on Part Numbers for details, pricing, or to buy online):

Notes:

Add "E" suffix for RoHS-compliant versions.
1 Oersted (Oe) = 1 Gauss in air.
Unipolar operation means exposure to magnetic fields of one polarity, for example 0 to +30 Gauss, or -2 to -50 Gauss. Bipolar operation (for example -5 to + 10 Gauss) increases nonlinearity and hysteresis.
