Low-Noise TMR Magnetic Field Sensor
Features and Benefits
The STJ-220 is Micro Magnetics' low-noise single-axis magnetic sensor in probe package. The sensor die features Micro Magnetics' low-noise SpinTJ sensor. The die is 0.89 mm square and 300 microns thick.
The field sensitivity of the STJ-220 is 5 nT/Hz0.5 at 1 Hz and better than 1 nT/Hz0.5 at high frequencies. These values are 10,000 and 50,000 times smaller than the magnetic field of the Earth, respectively.
The STJ-220 comes with a shielded multi-pin connector. This connector is designed to mate to our AL-05 signal conditioning board.
Micro Magnetics also offers custom solutions -- we design and build custom sensing products which are tailored to the customer's specific application.
