Miniature Square Photoelectric Sensor in plastic housing
E3T• Precision pinpoint LED
• 3.5 mm thin flat shape or 6.6 mm side
view shape where space is crucial
• IP67
• Pulse synchronisation for high
ambient light immunity
Features
3.5 mm flat model with background supression (BGS) with highest repeatability even for differently coloured objects.
Application
Object detection through small holes• The precision pinpoint LED of the through-beam models
provides appropriate sensing distances for very precise and reliable detection even through smallest slits and gaps with e.g. 0.5 mm dia.
• The coaxial optics and the small focal lens of the retro-reflective models allow the detection of small(dia 2 mm) objects or through small holes (dia 2 mm).
Minimal black/white error Unique light receiving lens shape
for high precision alignment
New mounting technology for reliable background
suppression in 3.5 mm flat housing

Sensors
E3T-SL limited-reflective models (side view)• Minimum detection object: 0.15 mm dia.• Limited-reflective optics reduce the influence of changing
backgrounds and surrounding metal for enhanced detec-tion stability.
E3T-FD Diffuse-reflective Models (Flat)• Minimum detection object: 0.15 mm dia.• 3.5 mm thickness for installations with limited space.

Safety Precautions
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.
Do not use the product in atmospheres or environment that
exceed product ratings.
WiringThe maximum power supply voltage is 24 VDC +10%. Before
turning the power ON, make sure that the power supply volt-
age is not more than maximum voltage.
Load short-circuit protectionThe 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 short-circuit protection function. The load short-
circuit protection function will work if there is a current flow
that is 2.4 times larger than the rated load current. When us-
ing an inductance load, be sure that the inrush current will not
exceed 2.4 times larger than the rated current.
MountingWhen mounting the Sensor, never strike it with a heavy ob-
ject, such as a hammer. Doing so may reduce its watertight
properties. Use M2 screws and flat or spring washers to se-
cure the Sensor. (Tightening torque: 0.15 N·m max.)
Mounting the Sensor on Moving Parts
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.
L
AdjustingIndicators• 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
gradually turn the adjuster counterclockwise toward theMin. side. Stop turning the adjuster when the operation in-dicator and stability indicator (green) turn ON.
5. Remove the workpiece and confirm that the operation in-dicator 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 stabilityindicator will not turn ON whether or not light is received. When the vari-ation of light is small such as when sensing semi-transparent workpiec-es, carefully perform preliminary testing.
OthersDo 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

BConsider models that use break resistant ca-
bles (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 thou-
sand times is far superior to that of standard
cable at approximately 14 thousand times.

*If the E3T fs operating level is set to the stable operation range, the E3Twill be in most reliable operation without being influenced by temperaturechange, voltage fluctuation, dust, or setting change. If the operating levelcannot be set to the stable operation range, pay attention to environmentalchanges while operating the E3T.
