obtained by measuring the voltage at pin 3 (the capacitor
pin) while the device is running. The peak and valley hold
voltage will represent the peak-to-peak value of the signal.
More accurate measurements can be taken by connecting
an extremely small capacitor (0.05 µF) from pin 3 to
ground. After the device is powered up and has switched
at least 64 times, a 1 kΩ bleed-off resistor should be
installed in parallel with the capacitor without powering
down the device. If the gear is then rotated at an ex-
tremely low speed, an analog representation of the gain-

adjusted signal can be measured at pin 3. Note that the
device should be re-powered at each air gap and the
above procedure repeated for accurate measurements. In
both cases, the analog signal may be compared to the
typical hysteresis of the device and device performance
can be estimated.
* In application, the terms “gear” and “target” are often
interchanged. However, “gear” is preferred when motion
is transferred.
