The HMR2300R detects the direction and strength of Earth’s magnetic field and communicates the X, Y and Z components directly via a serial bus. Due to Honeywell’s round strap-down design as opposed to a gimbaled flux valve, it has no moving parts to damage or wear out during severe flight conditions. The HMR2300R offers an ideal replacement for flux valve sensors in avionics systems. Also includes 55 bytes of EEPROM locations for data storage.
