*1. Values in parentheses indicate the minimum required distance between the Sensor and Reflector.
*2. The model number of the Emitter is expressed by adding an ”L ” to the set model number in the table. Example: E3T-ST11 -L 2M
The model number of the Receiver is expressed by adding a “D” to the set model number in the table. Example: E3T-ST11-D 2M
Orders for individual Emitters and Receivers are accepted. (Modifications are re quired for some models.)
*3. Models are available either with or without the E39-R37-CA Reflector included .

Variety of Connection Specifications
The models with the connection specifications marked with a black circle in the table are available. These are applicable only to M2-mounting
Sensors. The model number indication is a combination of the basic model and the connection specification.
NPN Output
*The sensing distance depends on the Reflector that is used. The sensing distance is 200 mm if an E39-R4 is used and 100 mm if an E39-R37-CA is used.
PNP Output
*The sensing distance depends on the Reflector that is used. The sensing distance is 200 mm if an E39-R4 is used and 100 mm if an E39-R37-CA is used.

Accessories (Order Separately)
Accessories for M2-mounting Sensors These accessories are not included with the Sensor. Order them separately if required.
*1.An arrow indicates the polarization direction. Mutual interference can be prevented by using different polarization directions for adjacent Emitters/Receivers.
*2. When using Through-beam Sensors (E3T-ST@@, E3T-FT@@), order one bracket for the Emitter and one for the Receiver.
*3. Order two Sets, one for the Emitter and one for the Receiver, for Through-beam Sensors (E3T-ST@@ or E3T-FT@@).
This is the Screw Set for mounting the Sensor to the Mounting Bracket. Order this Set if you loose the screws. Do not use this Screw Set to mount the Mounting
Bracket to the equipment.

Safety Precautions
Refer to Warranty and Limitations of Liability.
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, otherwis e the E3T
may rupture.
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 be not more than
maximum voltage.
Load short-circuit protection
The E3T incorporates a load short-circuit protection function. If th e
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 short-
circuit 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.
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
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.
Adjusting
Indicators
The following graphs indicate the status of each operating level.
Be sure to use the E3T within the stable operating range.
Use of E39-E10 Sensitivity Adjustment Unit
(Dark-ON: E3T-ST12)
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 g radually
turn the adjuster counterclockwise toward the Min. side. Stop
turning the adjuster when the operation indicator and stability
indicator (green) turn O N.
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 atten uation rate due t o 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·m when turning the adjuster.
Others
Do not install the E3T in the following locations.
Locations subject to excessive dust or dirt
Locations subject to direct sunlight
Locations subject to corrosive gas
Locations subject to contact with organic solvents
Locations subject to vibration and shock
Locations subject to contact with water, oil, or chemicals
Locations subject to high humidities that might result in
condensation

* 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.
