The differential magnetoresistive sensor FP 201 L 100 consists of two magnetically biased magneto resistors made from L-type InSb/NiSb, which in their unbiased state each have a basic resistance of about 125 Ω. They are series coupled as a voltage divider and are encapsuled in plastic as protection against mechanical stresses. This magnetically actuated sensor can be implemented as a direction dependent contactless switch where it shows a voltage change of about 1.3 V/mm in its linear region.
