			TMR Magnetic Microsensor Probe STJ-030 Click here for full STJ-030 TMR sensor description and datasheet Order Online Features and Benefits Superior field sensitivity of 5 nanotesla Active areas as small as 1x2 microns On-board ESD protection Small size Compact SMA connector Optional sensor polishing allows an approach distance of < 5 microns (0.0002") Product Description 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. [Return to SpinTJ Product Page] Copyright © 2002-2024 Micro Magnetics, Inc. All rights reserved.
