About
The Mag900 and Mag901 are low power, unpackaged 3-axis fluxgate magnetometers designed to provide high sensitivity magnetic field measurements. These devices are characterized by their narrow noise band and exceptionally low power consumption, making them particularly well-suited for perimeter surveillance applications. Their unpackaged design facilitates easy incorporation into multi-sensor systems. Key features include a noise band of ≤10pTrms√Hz @ 1Hz (after magnetic settling time) and a measuring range of ±60 and ±100µT. Beyond surveillance, these magnetometers are applicable for detecting vehicles and personnel carrying metal equipment, as well as for magnetic field measurement in remote locations and multi-sensor magnetic signature ranges. The product is also listed under ‘Space Products’ and ‘High Performance Magnetometers’ categories, indicating its suitability for demanding environments.
