AB001-00E GMR Gradient Sensors (Gradiometers) offer unparalleled magnetic gradient
sensing. Two pairs of unshielded GMR bridge resistors provide directional sensing
of small gradients over a wide range of magnetic field strength. The devices
are sensitive only to gradients, and have low sensitivity to constant magnetic
noise.
Differential magnetic field sensor (gradiometer) -- for gear tooth, multi-pole magnet, and high noise rejection sensing.

This part is RoHS compliant.
NVE's AD006-00E GMR Switch integrates GMR sensor elements with digital onboard
signal processing electronics. The GMR Switch has less field sensing errors than
other magnetic sensors, and magnetic field operate points are stable over voltage
and temperature extremes. This enables high precision, tight-tolerance magnetic
sensing assemblies.

Applications:
NVE's ADV001-00E is a GMR Digital Switch using a bipolar output GMR material.
This material allows the sensor to maintain an operate point with the application
of a negative (South) magnetic field, and a release point with the application
of a positive (North) magnetic field. The part is ideal for use with magnetic
encoders that have alternating North/South poles, or in any other application
where one polarity of field is required to turn the part on, and the opposite
polarity is required to turn it off.
