FP 412 L 100

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 Ω. The series coupled MRs are actuated by an

external magnetic field or can be biased by a permanent magnet and actuated by a soft

iron target.
