Transparent Object Detection
Photoelectric Sensor
E3S-DB
Reliable Detection of
Transparent Objects
These Photoelectric Sensors Contribute to the Food and Packaging Industries
by Detecting the Objects Regardless of Changes in Materials, Shapes, and Types.

Transparent Object Detection
Photoelectric Sensor
E3S-DB
High detection capabilities for stable detection of a wide range of
transparent workpieces in the food and packaging industries,
including glass bottles, PET bottles, films, and trays.
You can increase equipment operating rates and reduce
commissioning and maintenance work.
Improved Equipment Operating Rates
Prevent Intermittent
Line Stoppage and Shorten
Cycle Time with High Detection Capabilities
Increase Operating Efficiency for Transparent Bottle Detection
Typical
Problems
Detection of transparent bottles with
photoelectric sensors is not stable, which
prevents increasing equipment operating
rates. Sensors have to be selected on a
case-by-case basis or expensive laser sensors
have to be used.
These Photoelectric Sensors can stably detect
With the
E3S-DB transparent glass bottles so that you can
increase equipment operating rates.

Three Benefits for Transparent Object Detection
Improved
Equipment
Operating Rates
Reduced
Commissioning and
Maintenance Work
High detection capabilities
for stable detection.
Easy setup and operation.
High
Usability
Reliable Resistance to Water
and Detergents, and Ease of Use.
Increase Operating Efficiency to Detect Loose Shrinkwrapping
Typical
Problems
Detection of transparent film is not
stable, which prevents increasing
equipment operating rates.
This Is How
P-opaquing function
P-opaquing function ensures attenuation of 70%* even
with
films with little difference in light levels.
E3S-DB
Stable detection lets you increase equipment
operating rates.

This uses double refraction
to cut out polarized components
with OMRON's unique polarization filter.

*The data are obtained by OMRON
from measurement of cigarette pack film.
Shorten Cycle Time for Transparent Bottle Detection
Typical
Problems
When the pitch between glass or PET bottles on conveyor belts is too tight,
sensors do not have enough time to turn ON and OFF,
which prevents shortening the cycle time.
The narrow beam enables incident light
E3S-DB with gaps as narrow as 3 mm.*
You can reduce the pitch between workpieces
to maximize conveyance.
With the
This Is How
Narrow beam diameter
of minimum 2.5 mm
*When using the E39-R21 Reflector,
adjusting the threshold to 25% or less,
and using stationary workpieces.
Reflector
E39-R21
The E3S-DB has a response time of 0.5 ms
for a pitch of 5 mm, so detection is possible
at a conveyor speed of up to 4 m/s.
(With the E3S-DB
2(T) and a sensing
distance of 200 mm.)

Reduced Work
Easy Setup and Operation; Reduced
Commissioning and Maintenance Work
Large Reductions in Adjustment Time for Sensitivity and Threshold
Standard Sensor with Multi-turn Adjuster
E3S-DB Smart Teaching Type
You have to adjust the sensitivity adjuster
on each Sensor individually to achieve
the optimum sensitivity for each.
Set the optimum threshold and sensitivity by adjusting
the setting to the same scale (2 s)
and pushing a button (1 to 5 s).
Examples for Setting Five Sensors
With 11 turns, you end up turning the adjuster left
and right. Sensitivity depends on the installation location,
so all Sensors have to be adjusted individually.
1. Set the threshold
on the dial.
2. Push the

Visualization Reduces Work in Changeovers and Installation
Visible Spot
The visible spot in the Reflector lets you easily adjust
the height of the optical axis for detecting different
height of workpieces and reduces time required
for adjustment.

Reliable Structure That Resists Water and Detergents
Resistance to Detergents Certified by Ecolab
IP69K Water Resistance
Withstands harsh environments with high
temperatures and high water pressures.
Third-party certification has been received from
the Ecolab company in Europe for applications
in water-washed environments.
IP69K Degree
