FP 410 L (4 x 80) FM

The double differential magneto resistor assembly consists of two pairs of magneto
resistors, (L-type InSb/NiSb semiconductor resistors whose resistance value can be
magnetically controlled), which are fixed to a ferrite substrate. Contact to the magneto
resistors is achieved using a copper/polyimide carrier film known as Micropack.

The basic resistance of each of the magnetic resistors is 80 Ω. The two series coupled
pairs of magnetic resistors are actuated by an external magnetic field or can be biased
by a permanent magnet and actuated by a soft iron target.
