The differential magnetoresistive sensors CY-DMR-01, CY-DMR-01H, CY-DMR-02 and
CY-DMR-02H consist of two series coupled magneto resistors (D-type InSb/NiSb
semiconductor resistors whose value can be magnetically controlled), which are mounted
onto an insulated ferrite substrate. The sensors are encapsulated in a metallic or plastic
package and each of them has 3 connection terminals. The basic resistance of the total
system is from 2x120Ω to 2x300Ω. A permanent magnet, which supplies a biasing
magnetic field, is fixed on the base of the sensor.

Measurement Arrangement
Standard target object
A measuring bridge is used for applications of
the magnetoresistive sensors CY-DMR-01,
CY-DMR-01H, CY-DMR-02 and CY-DMR02H. The resistance of one sensor is changed
by approaching a small soft iron part (standard
target object) close to it. As result an output
voltage change of measuring bridge is caused
by the resistance change (see below).

To convert small distance into a proportional electric signal, one can use a small soft iron
part with definite width (e.g. b=1.8mm) to move over the face of the sensor. A linear signal
up to 1.5mm can be obtained in this way. The sinusoidal signal gives a voltage output
proportional to the distance in the zero crossover region.
