FP 412 D 250
The differential magneto resistor FP 412 D 250 is a magnetically variable resistor in D-
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 250
. 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.
