Description: The magnetic field sensor FMS-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 navigation) or if ferrous objects should be detected at larger distances. The FMS-100 is a complete single-axis fluxgate magnetometer which works without external drive circuits. The analog output voltage is proportional to the magnetic field component 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 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. Similar products: FLC-100, EMS-100, Ali-100
