The STJ-210 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-210 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-210 is available with a standard 0.1"-pitch female header. The mating connector can be supplied by Micro Magnetics or purchased from most electronics suppliers.


  • Superior field sensitivity of < 1 nanotesla
  • Field sensitivity of 5 nanotesla at 1 Hz
  • Compact sensor size (0.9x0.9x0.3 mm)
  • Linear, bipolar response
  • Tapered vertical probe design allows easy access to cramped areas
