Magnetic Length Sensor MLS
SENSOR BASICS
The MLS-sensors consists of two magneto resistive Wheatstone bridges, generating two phase-shifted
signals by means of a lateral offset. MLS-sensors will only cooperate well together with pole stripes meeting
their design-pole pitch.In addition, some sensor types integrate over more than one pole in order to improve
sensor performance.

n = 1;2 (bridge number); Stress above one or more of the limiting values may cause permanent damage to the device. Exposure to
limiting values for extended periods may affect device reliability.
