Mag678/679 Low Power Magnetic Field Sensors

Mag678 Compact Low Power Single Axis Fluxgate MagnetometerMag679 Compact Low Power Single Axis Fluxgate Magnetometer


This range of single axis magnetic field sensors provide high accuracy measurements of magnetic fields. With approximately 2.2mA current consumption and high environmental protection, these magnetometers are ideal for battery powered applications such as surveillance and perimeter security applications, and can be used as part of multi-sensor perimeter arrays. The Mag679 offers an extended bandwidth to 1kHz. Unpackaged versions can also be supplied.

These sensors are easily integrated into your own measurement platform, or can be combined with one of our Power Supply or Data Acquisition Unit to provide a complete measurement system.

Typical applications:
  • Vehicle monitoring & detection.
  • Perimeter security and surveillance.
  • Multi-sensor magnetic signature ranges.
  • Magnetic field measurement in remote locations.

  • Features:
  • Low current consumption 2.2mA typical.
  • Low noise optional <10pTrms/√Hz at 1Hz .
  • Measuring ranges of ±60 or ±100µT.
  • Two bandwidth option, >30Hz (Mag678) and >1kHz (Mag679).
