Introduction
SCATEC-2 has the same key feature as all the other sensors from the SCATEC family: The capability
of non-contact detection of object edges. SCATEC is the sensor of choice when it comes to detect flat
objects conveyed in an overlapping stream or individually. The sensors in the SCATEC family were
developed and highly optimized particularly with regard to the specific demands of non-contact counting
of overlapping paper sheets and newspapers. Therefore the printing industry will be the ideal area of
application for the SCATEC.
Generally speaking a SCATEC sensor reacts to an edge facing the sensor’s laser beam. If the laser
beam strikes such an edge, SCATEC responds with an electrical output pulse of fixed duration.The

Principle of operation
Baumer Electric AG
Frauenfeld, Switzerland
Within the SCATEC family, the SCATEC-J is characterized by the following properties:
3
•
•
6
www.baumer.com
Baumer Electric AG
Frauenfeld, Switzerland
The orientation of the object to the beam is significant.
An edge facing towards the beam creates a small
ration v/r, in contrast to an edge facing away from the
beam. Therefore only edges facing towards the laser
beam will be detected!
Edge detection is independent of the color, as only the
ratio of the light intensities and not the absolute value
is used for detection.
This principle of operation clearly demonstrates that:
Described simply, the SCATEC-J consists of a laser light source and two photodetectors. The beam is
aimed diagonally at the objects to be detected. Photodetector R is located close to the laser light source
and photodetector V in a forward sensing position. The sensor measures the ratio between signal v
(light propagated forwards) and signal r (light propagated backwards).
The ratio v/r differs widely depending whether the beam strikes on a flat surface or on an edge. When
an edge moves into the laser beam, the direct line of sight from detector V to the point of contact of the
laser is obstructed, which reduces signal v, and the edge
also increases the backwards propagation, causing signal r
to increase. Both effects cause ratio v/r to become
substantially smaller than with a flat surface. If ration v/r falls
below a specific level, the sensor interprets this as an edge.

The sensor responds to an edge

Block the laser beam after the objects
whenever possible.
Adjust the sensor so that the laser
beam is aimed towards the edges to
be counted. (When fitted correctly,
the overlap of the copies is facing in
the same direction as indicated in the
alignment aid.)
Mount the sensor at a height h of 40
mm (+5/-10 mm) with the front
window parallel to the working plane.

The resolution is dependent on the distance. The highest resolution of 1.5

7.3
Beam blocker
Cleaning the front window
Uncontrolled reflections of the laser beam can cause malfunctioning of the sensor or dazzle people.
Therefore, a beam blocker should be fitted whenever possible to block the beam when there is no target
present. A flat surface (at least approx. 25x25 mm) made of a matt, non-reflecting material is
recommended as the beam blocker. The beam blocker must be mounted parallel to the sensor. The
yellow edge indicator LED must not light when the laser beam strikes the beam blocker.

Checklist for correct fitting
Fingerprints, dust and other forms of dirt on the front window can impair the function of the sensor. It is
normally sufficient to wipe the glass pane dry with a clean (!), soft cloth. Alcohol may be used for
heavier soiling.

Dead time t
Yellow edge-LED
Since the output pulses and the dead time cannot overlap, edges must be separated by at least a dead
time. (With the SCATEC-J, the dead time t is always greater than the output pulse period p). If the
following edge arrives within a time shorter than the dead time, then this edge will be suppressed
meaning that the edge will not initiate an output pulse as illustrated in the figure below.
Manual SCATEC-J
Version 2010-04
Dead time
Therefore:
t = 12 ms
maximum counting rate = 1/12 ms = 300,000 per hour
15
www.baumer.com
Baumer Electric AG
Frauenfeld, Switzerland
The dead time t therefore determines the maximum counting rate because within time t, the SCATEC-J
cannot issue more than one output pulse.
Example:
The maximum counting rate is therefore 1/t.
Variation of the working distance
Please note that this is the maximum counting rate. The closer the actual production rate gets to this
value the higher the risk becomes that copies are suppressed due to too short intervals between copies.
If suddenly the Scatec-J starts to miss copies while the production rate is run up, the reason very often
are occasionally way too short intervals between copies. Such irregularities of the lap stream are very
often unexpected and difficult to see directly.
9.2
the sensitivity of the sensor varies with the working distance
Applications outside the paper processing industry
The thickness that an edge must have to be detected by the SCATEC-J depends on the working
distance. The SCATEC-J is most sensitive at a working distance of about 40 mm. The relationship
between the sensitivity and the working distance is contained in the specifications in Section 10.6.

Due to the fundamental principle of edge detection employed by the SCATEC-J, the field of application
for the sensor is not restricted to the paper processing industry. For applications concerning high-gloss
surfaces (e.g. sheet metals), it is advisable to consult a technician from Baumer Electric AG on the
application.

The SCATEC-J requires no maintenance apart from keeping the front windows clean. Dust or
fingerprints can impair the sensor function. It is normally sufficient to wipe the windows dry with a clean

13 Troubleshooting
Baumer Electric AG
Frauenfeld, Switzerland
Increase the overlap spacing or
reduce the conveying speed
Corrective actions
Prevent faulty points on the copies
Set the distance of the copies in a
range where the sensor is
sufficiently sensitive to detect the
copies. See chart 10.6
Prevent complete coverage of the
copies
a) Overlap spacing sporadically too
small
b) Copies to close to or too far away
from the Scatec, so that the copies are
in a distance range at which the
sensitivity of the sensor is inadequate
c) Some copies are covered by another
copy
b) Laser beam on beam blocker causes
spurious pulses
c) Unblocked laser beam is reflected
and causes spurious pulses
26
www.baumer.com
Baumer Electric AG
Frauenfeld, Switzerland
Adjust beam blocker correctly
(yellow edge LED must never light
when the laser beam strikes the
beam blocker)
Install beam blocker at proper
distance
Apart from the edges, there are other
points on the copies which cause
spurious pulses
Possible causes

www.baumer.com
What is the type designation and P-code of the sensor?
Exact description of the problem. (Does the SCATEC count more or less copies than
actually pass the sensor?)
Retain several samples of the products causing the counting error. (Mark the running
direction on one sample and the approximate line along which it passes the laser beam.)
If possible, digital images of the installed sensor in operation and the immediate
surroundings.
First try to resolve the problem using the following table. If this is unsuccessful, consult Baumer Electric
AG (www.baumer.com) for technical support.
The search for fault causes can be substantially shortened if the following issues are clarified before you
make contact with a technician from Baumer Electric AG:
