38 nec tokin sensors vol.1 outline ? terrestrial magnetic sensor use a flux gate type detector to detect terrestrial magnetism. ? it detects the horizontal component of the earth's magnetic field and divided it ioto twe perpendicular components, and determines the angle of direction from the resulting vector.this allows absolute direction angle measurements with reference to magnetics noth. applications compass for automoblies and ships cathode-ray tube fluxgate type terrestrial magnetic sensor speciffications shapes and dimensions ( mm ) 75.0 65.0 51 65.0 75.0 3.5 y-axis x-axis model TMC2000 tmc3000nf item code power supply voltage (v) vcc 12 0.5 12 0.5 supply current (ma) max. icc 50 35 output voltage (v) vx,vy 1 0.05(at 100 t) 1 0.05(at 30 t) offset voltage 4 0.3(at 0 t) 2.5 0.3(at 0 t) magnetic field range ( t) max. 200 60 output linearity (%) 100 15 100 2 operating temperature (?c) top - 10 to + 70 storage temperature (?c) tstg - 40 to + 85 pin description pin no. function signal name 1 vref reference voltage 2 vy y-axis output 3vx x-axis output 4gnd power supply ground 5 vcc power supply TMC2000
