TMR Magnetic Microsensor Probe
Features and Benefits
The STJ-030 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-030 to detect field signatures from single magnetic particles or microscopic magnetic media.
The field sensitivity of the STJ-030 is 5 nT, which is ten thousand times smaller than the magnetic field of the Earth. The geometry of the STJ-030 probe makes it perfect for magnetic imaging of currency, magnetic films, or media (see our image library for some relevant results).
The STJ-030 is a two-terminal device which is accessed through a standard SMA connector.
