ZMT31 - ANGLE SENSOR

Description

The ZMT31 allows the contactless counting of thr revolutions of a rotating magnet which is mounted on the axis of a wheel.

Zero output voltages of the Wheatstones bridges are used as trigger signals.

Features

  • Measures the magnetic field hrot (> 50kA/m) generated by a permanent magnet which rotates over the sensor.
  • Magnetic field hrot parallel to the chip surface causes a sinusoidal output signal.
  • Package : SM-8 (available on 12mm tape) PINOUT.

ZMT31 ANGLE SENSOR DESCRIPTION The ZMT31 allows the contactless counting of thr revolutions of a rotating magnet which is mounted on the axis of a wheel. Zero output voltages of the Wheatstones bridges are used as trigger signals. The sense of rotation of the wheel is taken into account by comparing the signal outputs of both Wheatstone bridges which are proportional to sin2(␣) or sin2(␣+45Њ). the angle can be determined by evaluating these signals. Alternatively it is possible to use the voltage signals of four half bridges which are trimmed on Vb/2.
