Contact to the magneto resistors is achieved using a copper/polyimide carrier film known as TAB. The basic resistance of each of the magneto resistors is 90 Ω. The two series coupled pairs of magneto resistor are actuated by an external magnetic field or can be biased by a permanent magnet and actuated by a soft iron target.
