Introduction
The second purpose of the flux concentrators is to vary the sensitivity of the sensor element from
product to product. They work by forming a low reluctance path to the sensor elements placed between
them. NVE uses a “rule of thumb” formula to calculate the effect of the flux concentrators:
Field at sensor elements ? (Applied Field)(60%)(FC length / gap between FCs)
For the sensor shown in the previous photo, the length of each flux concentrator is 400 microns, and
the gap between the flux concentrators is 100 microns. Therefore, if the sensor is exposed to an applied
field of 10 Gauss, the actual field at the sensor element will be about (10 Gauss)(0.6)(400 microns /
100 microns), or 24 Gauss.
NVE uses this technique to provide GMR sensors with varying sensitivity to the applied magnetic
field. The following chart shows sensitivity ranges for some of NVE’s products. Sensitivity to the
magnetic field is indicated by the slope of each line:

Applied Magnetic Field (Gauss)
Maximum signal output from such a sensor element is typically 350 mV at 100 Gauss with a 5V power
supply. This compares to an output of 5 mV under the same conditions for a Hall sensor element, and
100 mV for an AMR sensor.
