Description

The double differential magneto resistor assembly FP420L90 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 silicon substrate. Contact to the magneto resistors is achieved using a copper/polyimide carrier film known as TAB.

The basic resistance FP420L90 of each of the magneto resistors is 90 W. The two series coupled pairs of magneto resistors are actuated by an external magnetic field or can be biased by a permanent magnet and actuated by a soft iron target.
