MEASUREMENT PRINCIPLE

Figure 1: principle function of the sensor

The KMXP sensors consist of two magneto resistive Wheatstone bridges, whose resistors are placed in a such way

that the characteristic magnetic field distribution of a magnetic scale with matching pole pitch produces a sine and

a cosine signal output when the sensor is moved along the scale.

signal voltage depending on sensor position
