A405x
A405x
The A405X series modules are designed to interface a fluxgate magnetometer sensor with display or computer systems. They provide two analogue outputs for orthogonal sensors, useful in applications like compass and field sensing, treasure finding, and geomagnetic surveys. The modules can accept currents to create nulling fields to counteract the Earth's magnetic field.

Catalog excerpts
A405XOEM 2-AXIS ANALOGUE MAGNETOMETER FEATURES • COMPLETE OEM ANALOGUE COMPASS • ANALOGUE SIN/COS • ISOLATED NULL WINDING • FULL OUTPUT FROM 2.5|jT to 50|jT DESCRIPTION The A405X series of modules is designed to interface a fluxgate magnetometer sensor to a display or to computer systems. There are two analogue outputs, one for each orthogonal sensor, so that it can be used for compass and field sensing for treasure finding or archeo-magnetic or geomagnetic surveys. In such applications an external nulling field is sometimes needed to remove the Earth’s field. Each member of the A405xseries has extra independent windings to accept currents to create these nulling fields. ABSOLUTE MAXIMUM RATINGS
