Magnetic Field Sensors

Containing two sensitive magnetic field sensors, the ZMX40M accurately measures linear position and high voltage current. Thin film permalloy stripes covering each sensor chip form a Wheatstone bridge. This provides an output voltage proportional to the magnetic field (Hy) running the length of the SM8 package. Internal permanent magnets create a perpendicular field (Hx) that suppresses hysteresis and biases the sensor in their linear region. The ZMX40M can resolve distances down to 30μm in toothed wheel automotive and machine tool applications.
