to achieve the industry’s smallest visible
red beam
Self-contained sensor ideal for
space-restricted applications
“Pin-point” beam for detecting extremely
small objects
Offered in both flat and rectangular
body styles
Retroreflective model employs Omron’s
Free-Angle Optics technology (FAO) to
detect objects as small as 2 mm dia.
Convergent-beam model spot diameter
is 0.15 mm
Through-beam model is capable of
sensing distances of 1 meter with a 2 mm
target diameter
CE conformance

3. Adjust the optical axis (align) and tighten mounting
hardware.
4. Place a target between 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 target and confirm that the operation
indicator is OFF and the stability indicator (green) is
ON.
Note: For Light-ON, adjustment is similar, except that
indicators would operate in opposite manner as
with Dark-ON.

Precautions
J LOAD SHORT-CIRCUIT PROTECTION
Caution
J AVOID DAMAGE TO THE E3T
•
•
•
Do not exceed the rated voltage on the E3T.
Do not short-circuit the load connected to the E3T.
When supplying power to the E3T, make sure that the
polarity of the power is correct.
J OPERATING ENVIRONMENT
To avoid malfunction, DO NOT install the E3T in the following
environments:
•
•
•
•
Locations where the E3T is exposed to intense sunlight.
Locations with high humidity and where condensation may
result.
Locations with corrosive gas.
Locations with vibration or shock affecting the E3T.
J HIGH-TENSION LINES
To avoid Sensor damage or malfunctioning due to induction
noise, do not place the power supply lines of the Photoelectric
Sensor within the same conduit as power lines or high-tension
lines.
The E3T incorporates a load short-circuit protection function. If
the load short-circuits, the output of the E3T will be turned OFF.
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 using an inductance load, be sure that the inrush current
will not exceed 2.4 times larger than the rated current.
J CLEANING
DO NOT apply paint thinner when cleaning the E3T. Paint thinner
will damage the casing of the E3T.
J INDICATORS
The following graphs indicate the status of each operation level.
Be sure to use the E3T within the stable operating range.

J CABLE
The cable can be extended up to 100 m provided that cable
thickness does not exceed the 0.3 mm2 maximum.

Avoid damage to the E3T: NEVER apply AC power to the E3T.

When the E3T’s operation level is set to the stable
operation range, the E3T will be in its most reliable
operation without being influenced by temperature,
voltage fluctuation, dust, or mounting changes.
If a switching regulator is connected to the E3T, you must ground
the FG (frame ground) and G (ground) terminals, or the switching
noise of the switching regulator may cause the E3T to
malfunction.

Do not use the E3T underwater, outdoors, or in the rain.
Use M2 screws and washers to mount the E3T. When
mounting the E3T, NEVER strike the E3T with a hammer, or
the E3T will lose its watertight properties.

The E3T will be ready for sensing 100 ms after the power is
turned ON.
If the E3T is connected to a power source different from one
for loads, be sure to turn ON the power supply to the E3T
first.
