PRECISE MEASUREMENT
OPTICAL DISTANCE SENSORS
In highly automated systems in intralogistics and production,
precise monitoring and measurement of distances is essential
for smooth running in daily operation.
Distance sensors are used for this purpose in, for example, object measurement,
quality assurance in assembly lines or for collision protection of shuttles.
We offer a comprehensive product range of optical distance sensors that enables
pinpoint measurement, positioning and quality assurance of any objects over long
and short distances.
Our sensors are based on various measurement operating principles (triangulation
measurement, time of flight measurement, phase measurement). These enable
both the reproducible measurement of distances in the range of tenths of a
millimeter as well as over larger distances in excess of 60 meters. The measure-
ment data can be transferred with IO-Link and evaluated with software in the
machine. Based on the current values, production processes can be constantly
adapted and optimized.

TAILOR MADE
Depending on requirements, sensors with various operating ranges, resolutions
and reproducibilities are needed. To optimally cover the needs, we use various
technologies in our sensors that are based on proven measurement procedures.
Triangulation measurement
Transmitter
CCD-Line
With triangulation measurement, the laser beam is reflected
by the object. This is incident on a high-resolution receiving
array. The distance to the object is determined based on
the point of incidence. This process is suitable for ranges up
to approximately one meter and if very high resolutions are
necessary.
Transmitter
Receiver
Transmitter
Receiver
Time of fl ight measurement (TOF)
With time of flight measurement, pulsed light is emitted. The
propagation time for the light to return to the receiving lens is
measured and used to calculate the distance to the object.
This process is suitable if sensors with a compact construc-
tion are to be used to measure operating ranges of up to ten
meters. It offers high reproducibility and color independence.
Phase measurement
During phase measurement the distance to the object is
calculated from the shift of the phase angle between the
transmitted and reflected light. This process is particularly
advantageous if distances in excess of ten meters are to be
measured with high resolution. Due to the sophisticated
technology, sensors that are based on this measurement
procedure have a larger size.

OPTICAL DISTANCE SENSORS
AT A GLANCE –
THE RIGHT SENSOR
Operating range and resolution are the most important criteria when selecting the right
measuring sensor. For positioning applications, reproducibility is another important factor.
Because sensor systems need to be integrated in machines and systems in a space-saving
manner, the size is also of great relevance.

APPLICATIONS
Object measurement
Requirement: During
machining processes, the raw
material must be prepared in
the same width for further
processing. To facilitate
this, the width is constantly
measured on the materials
handling system – in a higher
or lower resolution depending
on the object.
Material thickness measurement
Requirement: To ensure an
optimum punching process,
the material thickness must be
checked. This is performed by
measuring the distance to the
material with high resolution.
Solution:
The ODSL 8 and ODS 9
sensors with different resolu-
tions and operating ranges
enable the measurement of
objects of any size and shape.
Solution: The ODSL8 and
ODS 9 sensors measure the
distance with resolutions of
up to 0.01 mm and thereby
supply the basis for a high
quality of this process step.
Quality assurance
Requirement: During assem-
bly processes, the complete-
ness or alignment of individual
components must be ensured.
To do this, reference points
must be defi ned and checked.
6
Solution: Due to their high
resolution at close range, the
ODSL8 and ODS 9 sensors
are suitable for checking
reference points. Robust
plastic and metal housings
are available.
Stack height measurement
OPTICAL DISTANCE SENSORS
SELECTION GUIDE
|
Requirement: With machining
processes, the raw material
must be fed into the machine
without interruption. To ensure
this, the stack height on the
load carrier must be constantly
detected.
Sag/loop control
Requirement:
clocked processes, raw
material is fed in from coils,
loop control must be per-
formed to compensate for
feed fl uctuations. To do this,
it is necessary to check how
taut the material is tensioned.
By feeding in material in a
timely manner, breakage is
prevented.
If, during
Solution: Our wide selection
of distance sensors with vari-
ous resolutions and operating
ranges enables height mea-
surement of different stacked
objects.
Solution: The tension of
the material can be monitored
by measuring the sag.
Due to their various light-spot
geometries, the ODSL 8,
ODS 10 and ODSL96 sensors
can reliably measure the sag of
a wide range of different
material surfaces.

Collision prevention for shuttles
Requirement: Shuttles in
high-bay warehouses must
detect the end of an aisle in
good time. They can thereby
slow down in a targeted and
timely manner before reaching
the mechanical limit stop.
Solution: Thanks to their
compact construction, the
ODS / HT 10 and ODS / HT110
sensors can easily be integrated
in shuttles. They measure the
distance to the limit stop at the
end of the aisle and deliver the
measurement value to the
microcontroller of the shuttle.

APPLICATIONS
Load positioning with shuttles
Requirement: In a warehouse,
pallets of many different colors
and materials are deposited
by shuttles. To avoid collisions
here, a certain spacing must
be maintained.
Push-through protection
Requirement: To avoid a
push-through in multi-depth
pallet warehouses, the pallet
foot and its movement must
be reliably detected from long
distances.
Solution: Thanks to their
compact construction, the
ODS / HT 10 and ODS / HT110
sensors can easily be integrated
in shuttles. Through time of fl ight
measurement, the distance is
detected independent of color.
Solution: The ODS / HT 10,
ODS / HT 110 and ODSL 96
sensors detect the pallet
foot at a range of up to eight
meters thanks to their focused
laser. With switching product
models, the movement of the
pallet can be detected with the
help of the window function.
Shelf positioning, single or multi-depth
Requirement: When storing
pallets with a high-bay storage
device, the upper edge of the
shelf rack must be detected
for the vertical positioning so
that the “fork” can move in to
the correct distance.
8
Solution: The ODS10 and
ODS110 sensors can detect
shelf racks at a distance of up
to eight meters – independent
of environmental infl uences.
