TMR Solid-State Magnetic Sensor, Micro Sensor, Die Form (STJ-001) Helmholtz Coils a glass bulbMicro Magnetics' low field magnetic microsensor in die form. The sensor die features a Micro Magnetics SpinTJ sensor with an active (sensing) area of just a few microns (~0. 0001") in size. The die is 1. 9 mm square and 300 microns thick. It has four gold wire bonding pads which allow four point measurement of the device resistance. The active area of the sensor is located at one corner of the die to allow the sensitive region to be brought very close
