The differential magneto resistor FP 412 L 100 is a magnetically variable resistor in L-
type InSb/NiSb semiconductor material. The MR is glued onto a ferrite substrate and is
supplied in a "MICROPACK" copper/polyimide film package. The basic resistance of
each of the magneto resistors is 100
external magnetic field or can be biased by a permanent magnet and actuated by a soft
iron target.
