Infineon Technologies GMRB6
Giant Magneto Resistive Position Sensor
FEATURES
● GMR sensor in SMD package● Sensitive to the direction, not to the intensity of the magnetic field
● Constant TC of basic resistance R and magneto resistance ∆R
APPLICATIONS
● Rotation and linear sensing with large airgaps● Angle encoders
● Contactless potentiometers
