The ratiometric output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The CH601 family has a quiescent output voltage that is 50% of the supply voltage. The integrated circuitry provides increased temperature stability and sensitivity. The CH601 provide high accuracy and temperature compensation. The linear hall sensors have an operating temperature range from -40 to +150℃, appropriate for home appliances, industrial and automotive environments. They respond to either South or North pole.

Function Description The CH601 family MRL (Miniature Ratiometric Linear) sensors are small,versatile linear Hall effect devices which are operated by the magnetic field from a permanent magnet or an electromagnet. The ratiometric output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The integrated circuitry provides increased temperature stability, sensitivity and temperature compensation. These linear position sensors have an operating temperature range of -40oC to +150°C, appropriate for industrial and automotive environments. They respond to either positive or negative gauss, monitoring either or both magnetic poles. The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output. The product providing a robust design over a wide temperature range. Rail-to-rail operation (over full voltage range) provides a more usable signal for higher accuracy. The CH601 family has a typical sinking or sourcing output of 1.5 mA continuous, uses 4 mA of supply current at 5.0 volts and 25oC, and provides predictable performance over the full temperature range. The CH601 family Series sensors have wider null and sensitivity tolerances. 6. Magnetic Activation 7.
