Electrical Characteristics (TA = 25°C) Measuring Arrangements By approaching a soft iron part close to the sensor a change in its resistance is obtained. The potential divider circuit of the magneto resistor causes a reduction in the temperature dependence of the output voltage VOUT .

  1. Linear Distance Measurement To convert small distances into a proportional electric signal, a small soft iron part of definite width (e.g.b = 1.8 mm) is moved over the face of the sensor. Proportional signals for distances up to 1.5 mm can be obtained in this way. The sinusoidal output signal gives a voltage proportional to distance in the zero crossover region (seeFigure 3).
