Mag648/649 Low Power Magnetic Field Sensors

Mag648 Compact Low Power Three-Axis Fluxgate Magnetometer  Mag648U Unpackaged Low Power Three-Axis Fluxgate Magnetometer


This range of three-axis magnetic field sensors provide high accuracy measurements of magnetic fields. With current consumption from 2.6mA and high environmental protection, these magnetometers are ideal for battery powered applications, and can be used as part of multi-sensor perimeter arrays.
Designed for surveillance and perimeter security applications, the Mag648 is available in variants suitable for use on land or underwater (submersible to 2000m). The Mag649 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 from 2.6mA typical.
  • Noise levels from > 10 to ≤ 20pTrms/√Hz at 1Hz .
  • Measuring ranges of ±60 or ±100µT.
  • Two bandwidth option, >30Hz (Mag648) and >1kHz (Mag649).
