Schematic diagram
The magnetic field sensor FLC 100 is a miniature fluxgate magnetometer with high resolution for the measurement of weak magnetic fields up to 100 µT. This sensor can be used in any application where the sensitivity and stability of conventional magnetic field sensors (Hall or MR sensors) is too low, e. g. for the measurement of the earth’s magnetic field (for avigation) or if ferrous objects should be detected at larger distances. The FLC 100 is a complete single axis fluxgate magnetometer which works without external drive circuits. The analog output voltage is proportional to the component of the magnetic field parallel to the detection coil. Due to its single 5 V supply voltage and low current consumption it is ideally suited for battery powered or µP controlled applications The supply and signal lines are connected to solder pads which are positioned at nodes of a 0.1 inch grid. The excitation frequencies (typ. 17 kHz) of several sensors can be synchronized by connecting the SYNC pads to each other.
