TMR Magnetic Microsensor Probe
Features and Benefits
The STJ-020 is a low-field magnetic sensor probe designed for magnetic imaging and scanning applications. The sensor probe features a Micro Magnetics SpinTJ sensor with an active (sensing) area of just a few microns (~0.0001") in size. This allows the STJ-020 to detect field signatures from single magnetic particles or microscopic magnetic media.
The field sensitivity of the STJ-020 is 5 nT, which is ten thousand times smaller than the magnetic field of the Earth. The geometry of the STJ-020 probe makes it perfect for magnetic imaging of currency, magnetic films, or media (see our image library for some relevant results).
The STJ-020 comes with a shielded multi-pin connector. This connector
is designed to mate to our AL-05
signal conditioning board to create a full micron-resolution magnetic
sensing solution. Micro Magnetics also supplies the mating connector for
