Distance between two successive edges, measured along the
conveying plane. (Also referred to as the object spacing.)
Thickness of the copy at the point where the edge is to be detected.
The edge of an object facing the laser beam. Front edges are detected
by the sensor.
The edge of an object facing away from the laser beam. Tail edges are
not detected by the sensor unless they are pointing upwards.
The preferred running direction (front edges leading) is indicated. The
opposite direction is also permitted by the SCATEC-2.
The sensor responds to an edge with an output pulse with length p. The
dead time begins when the pulse
is issued. The sensor can only
issue the next pulse after both the
dead time t and the output pulse p
have expired. This means: an
edge detected by the beam while
still either the dead time t or the the
output pulse p is on does not
initiate an output pulse.
Output pulse generated by an
edge which should not be counted.
