Standard AI-Tek sensors are designed to operate with gears of 8 or 20 pitch, and new designs
should incorporate these. For applications using other pitch gears or other irregular disconti-
nuities consult the AI-Tek Industrial Products Catalog.
The pulse signal for channel A enters the instrument through terminals 1 (freq. +) and 2 (freq. -).
The pulse signal for channel B enters the instrument through terminals 4 (freq. +) and 5 (freq. -).
6.3.1 Passive Sensors
The figure below illustrates the use of a Passive Sensor connected to channel B producing an
AC signal.
