E3T-CT14

Ultracompact, Ultrathin Photoelectric Sensor with Built-in Amplifier
E3T
The Improved E3T Series with Easier,
Smoother Mounting and Installation
• The series includes Through-beam, Long-distance (2 m) Sensors
(E3T-ST3@).
• Easy installation with M3-mounting Sensors
(E3T-ST@@M, E3T-FD@@M, and E3T-SL@@M).
• Small Cylindrical Sensors for one-point mounting are also available
(E3T-C@@@(S)).
• Infrared Sensors added to the Series
(E3T-@T@@(M)F).
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.

Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for ensuring
safety of persons. Do not use it for such purpose.
● Adjusting
Indicators
• The following graphs indicate the status of each operating level.
• Be sure to use the E3T within the stable operating range.
Stability
indicator
(green)
Precautions for Correct Use
Do not use the product in atmospheres or environments that exceed
product ratings.
● Wiring
The maximum power supply voltage is 26.4 VDC. 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.
Light
Do not apply AC power to the E3T, otherwise the E3T
may rupture.

* If
the E3T’s 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.
Use of E39-E10 Sensitivity Adjustment Unit

● Mounting
When mounting the Sensor, never strike it with a heavy object, such
as a hammer. Doing so may reduce its watertight properties. Use
screws with spring, flat, or toothed washers to secure the Sensor.
Tightening Torque
M2-mounting Sensors: 0.15 N·m max
M3-mounting Sensors: 0.5 N·m max
Small Cylindrical Sensors: 1 N·m max
Attachment to Moving Parts
To mount the Photoelectric Sensor to a moving part, such as a robot
hand, consider using a Sensor that uses a bending-resistant cable
(robot cable).
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.
E3T-CD@@ Sensitivity Adjustment
Use the special screwdriver that is provided with the Sensor to adjust
the sensitivity. Do not exceed 0.8 N·cm when turning the adjuster.
● Others
Do not use the product under the following conditions.
• In the place exposed to the direct sunlight.
• In the place where humidity is high and condensation may occur.
• In the place where corrosive gas exists.
• In the place where vibration or shock is directly transmitted to the
product.
