2 BASIC FUNCTION
The DENEX Edge Detector II is a non-contact sensor, which counts all kinds of printed
products on an overlapped stream. It senses the leading edge and generates one output
pulse for every product. Product thickness from a single folded sheet up to a maximum
stream thickness of 70 mm can be sensed without adjustments.
The laser diode that is used produces a visible and very intensive and focused light beam
that is projected onto the stream. The reflected light from the spot is collected by two light
sensitive detectors P and R and is analyzed by a microprocessor. The difference in
reflected light that occurs, when the light spot is temporarily hidden behind the passing
product edge provides the basic data for the sensor to determine a count output pulse.
Figure 2.1 The principle of operation
The microprocessor controlled DENEX Edge Detector II can be adapted to different
operating modes by changing DIP-switches, which can be reached from outside, via the
lid.
