Magnetic Sensors

Precision in an imprecise world...

NVE is a leader in spintronic sensors. NVE sensors are smaller, more sensitive, and more precise than conventional sensors such as Hall effect or AMR. NVE developed the first commercial spintronic GMR sensors in 1995.

Since then, our product line has grown to include a range of: We also provide sensors with custom magnetic, electronic, and packaging specifications.
