MS32 Switching Sensor

DESCRIPTION

The MS32 is a magnetic field sensor which is built in the form of a Wheatstone bridge. Each of its four

resistors is made from Permalloy, a material that shows the anisotropic magneto resistance effect. An

unidirectional magnetic field in the surface parallel to the chip (x-y plane) along the y-axis will deliver a

field dependent output signal. A magnetic switching point, which is almost independent on

temperature is typically set to Hs=1.85 kA/m. In addition, the characteristic curve is linear over a wide

magnetic field range. Thus, the new MS32 simplifies the adaption of the sensor to different mechanical

and magnetical environments. The sensor die is packaged in a modern TDFN package.
