3-Axis Magnetic Sensor
Features and Benefits
Micro Magnetics' STJ-3D is an integrated 3-axis magnetic solid-state sensor used to measure absolute magnetic field vectors with three field components along the X-, Y-, and Z-axis. Based on the state-of-the-art technology of magnetic quantum mechanical tunneling junction (MTJ), the sensor is featured with high sensitivity, large dynamic range, low signal noise, and low power consumption. The STJ-3D is easy to use, requiring only an applied voltage (up to 24V). It outputs three corresponding voltages for 3-axis magnetic field components. There is no need to regularly apply a large current pulse to cure the magnetic structure disordered by field sensing, as needed by other types of sensors. The internal magnetic structure of STJ-3D is robust against even Tesla-scale external field, remaining operational as a fresh sensor after extensive use.
STJ-3D operates in a wide frequency range between DC to about 7 MHz. The applied voltage can be either DC or AC. Electronic noise can be minimized by using AC modulation on the applied voltage.
One advantage of STJ-3D is that it has a built-in thermometer, allowing the measurement of both temperature and magnetic field to be measured simultaneously.
Micro Magnetics' STJ-3D is ideally suited for a wide range of applications.
Micro Magnetics also offers custom solutions -- we design and build custom sensing products which are tailored to the customer's specific application.
