Photoelectric Sensor with Built-in
Amplifier Contributes to Equipment
Downsizing
• Ultracompact and Thin Photoelectric Sensor with Built-in
Amplifier
• Easy optical axis adjustment with emitter fluctuation of ±2% max.
for Through-beam Models.
• Product lineup includes Coaxial Retro-reflective Models that
support positioning applications.
• Product lineup includes BGS* Reflective Models unaffected by
background (E3T-FL1@/-FL2@).
• Product lineup of models with a variety of connection
specifications.
(e.g., robot cable and Smartclick pre-wired connectors)
* BGS (Background Suppression) technology prevents detecting background objects.
Be sure to read Safety Precautions on
page 14.
Features
E3T-SR4@
: Retro-reflective Sensor with Enhanced
Compactness and High Performance
• Perform detection from a small hole.
With a coaxial optical system, the lens diameter is only 2 mm.
Sufficient incident light is obtained even through a small hole.
The Coaxial Retro-reflective Sensor can be used for reliable application with positioning.
• Improved Stability of Short-distance Detection
A detection distance as short as 10 mm can be used with a Tape Reflector.
Detection is stable through a hole whether the distance is 10 mm or 100 mm (except in combination with the
E39-R4).
E3T-FL1@/-FL2@: The Slimmest BGS (Background Suppression) Reflective Photoelectric
Sensors in the World
Ultra slim at 3.5 mm and
black/white error of only
15%.
For example, the E3TFL1@ can stably detect a
black object at 12 mm
without being affected by a
white background at
20 mm.
OMRON provides BGS
performance sharper than
the previous Convergentreflective Sensors.

* Models numbers for Through-beam Sensors (E3T-@T@@) are for sets that include both the Emitter and Receiver.
The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3T-ST11-L 2M), the model number of the Receiver, by adding "-D" (example:
E3T-ST11-D 2M.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.

This product is not designed or rated for ensuring
safety of persons. Do not use it for such purpose.
Do not apply AC power to the E3T, otherwise the E3T
may rupture.

● Wiring
The maximum power supply voltage is 24 VDC +10%. Before turning
the power ON, make sure that the power supply voltage is not more
than maximum voltage.
Load short-circuit protection
The E3T incorporates a load short-circuit protection function. If the
load short-circuits, the output of the E3T will be turned OFF. Then,
recheck the wiring and turn on the E3T again to reset the load shortcircuit protection function. The load short-circuit protection function
will work if there is a current flow that is 1.5 times larger than the rated
load current. When using a capacitance load, be sure that the inrush
current will not exceed 1.5 times larger than the rated current.

• The following graphs indicate the status of each operating level.

*If the E3T fs operating level is set to the stable operation range, the E3T
will be in most reliable operation without being influenced by temperature
change, voltage fluctuation, dust, or setting change. If the operating level
cannot be set to the stable operation range, pay attention to environmental changes while operating the E3T.

● Mounting
When mounting the Sensor, never strike it with a heavy object, such
as a hammer. Doing so may reduce its watertight properties. Use M2
screws and flat or spring washers to secure the Sensor.
(Tightening torque: 0.15 N·m max.)
Mounting the Sensor on Moving Parts
Consider models that use break
resistant cables (e.g., Robotics Cables)
if the Sensor will be mounted on a
moving part, such as a robot hand. The
flexing resistance of Robotics Cable at
approximately 400 thousand times is far
superior to that of standard cable at
approximately 14 thousand times.
Cable Bending Rupture Test
(Tough Cable Breaking Test)
The cable is repeatedly bent with power
supplied to check the number of bends
until the current is turned OFF.

1. Mount the Unit on the Receiver.
2. Set the adjuster of the Sensitivity Adjustment Unit to Max.
(Before shipping: Max.)
3. After mounting on the Sensor, adjust the optical axis and secure the
Sensor.
4. Place a workpiece between the Emitter and Receiver and gradually
turn the adjuster counterclockwise toward the Min. side. Stop
turning the adjuster when the operation indicator and stability
indicator (green) turn ON.
5. Remove the workpiece and confirm that the operation indicator is
OFF and the stability indicator (green) is ON. This completes the
adjustment.
Note: If the light attenuation rate due to a workpiece is 40% or less, the stability
indicator will not turn ON whether or not light is received. When the
variation of light is small such as when sensing semi-transparent
workpieces, carefully perform preliminary testing.

Application Considerations
SUITABILITY FOR USE
OMRON shall not be responsible for conformity with any standards, codes, or regulations that apply to the combination of products in the customer's
application or use of the products.
At the customer's request, OMRON will provide applicable third party certification documents identifying ratings and limitations of use that apply to the
products. This information by itself is not sufficient for a complete determination of the suitability of the products in combination with the end product,
machine, system, or other application or use.
The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
• Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
• Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles,
safety equipment, and installations subject to separate industry or government regulations.
• Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE
SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCTS ARE PROPERLY RATED AND
INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
PROGRAMMABLE PRODUCTS
OMRON shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
Disclaimers
CHANGE IN SPECIFICATIONS
Product specifications and accessories may be changed at any time based on improvements and other reasons.
It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
PERFORMANCE DATA
Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the
result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.
