Adjustment Methods
●Adjusting the E3S-LS10XE4 Convergent-reflective
Sensor
1. Attach the distance adjustment scale as shown in the figure
and set it where the *mark is equal to the sensing distance.
2. Turn the distance adjuster until the red spot is at point
(center of the distance adjustment scale).
3. Remove the distance adjustment scale once the distance
has been adjusted. Put a sensing object in place, and then
adjust the sensitivity.
●Adjusting the E3S-LS20XE4 Convergent-reflective
Sensor
Adjustment Method 1
Use this method if the sensing object is more reflective than
the background.
1. Set the sensitivity adjuster to the center as shown in the
figure.
2. Turn the distance adjuster counterclockwise until it is fully
turned (L to S).
3. Position the sensing object.
4. Slowly turn the distance adjuster clockwise (S to L).
5. Eventually the LIGHT (red) indicator will light. Turning the
adjuster further will light the STABILITY (green) indicator.
Leave the distance adjuster at this level.
6. Adjust the sensitivity in this state.
Adjustment Method 2
Use this method if the background is more reflective than the
sensing object.
1. Set the sensitivity adjuster to the center as shown in the
figure.
2. Turn the distance adjuster clockwiseuntilitisfullyturned(S
to L).
3. Remove the sensing object.
4. Slowly turn the distance adjuster counterclockwise (L to S).
5. Eventually the LIGHT (red) indicator will light. Turning the
adjuster further will light the STABILITY (green) indicator.
6. Adjust the sensitivity in this state.
Distance adjustment scale
Align the distance adjustment scale
with the groove on the Sensor.

Safety Precautions
Be sure to read the precautions for all models in the website at: http://www.ia.omron.com/.
Warning Indications
Meaning of Product Safety Symbols
This product is not designed or rated for
ensuring safety of persons.
Do not use it for such purposes.
The following precautions must be observed to ensure safe
operation.
1.Doing so may cause damage or fire. Do not install the
product in the following locations.
•Locations subject to direct sunlight
•Locations subject to condensation due to high humidity
•Locations subject to corrosive gas
•Locations subject to vibration or mechanical shocks
exceeding the rated values
•Locations subject to steam
•Locations subject to strong magnetic field or electric field
2.Do not use the product in environments subject to
flammable or explosive gases.
3.Do not use a voltage in excess of the operating voltage
range. Applying a voltage in excess of the operating
voltage range, or applying AC power to a DC Sensor may
cause explosion or burning.
4.Doing so may cause damage, fire, explosion or
malfunction.
•Never use the product with damaged body or cable.
•Never disassemble, repair nor tamper with the product.
•Never use the product with incorrect power supply or
wiring.
5.Do not short the load. Otherwise explosion or burning may
result.
6.Do not use the Sensor in environments where the cables
may become immersed in oil or other liquids or where
liquids may penetrate the Sensor. Doing so may result in
damage from burning and fire, particularly if the liquid is
flammable.
7.Do not use in water or outside.
8.When disposing of the product, treat it as industrial waste.
1.Do not use the product in any atmosphere or environment
that exceeds the ratings.
2.Use M4 screws to mount the sensor and tighten each
screw to a maximum torque of 1.2 N
- m.
3.Do not apply the forces on the cable exceeding the
following limits:
Pull: 40 N; torque: 0.1 N
- m; pressure: 20 N; bending: 29.4 N
4.Make sure to tighten the connectors.
5.It may take time until the incident level and measurement
value become stable immediately after the power is turned
on depending on use environment.
6.Burn injury may occur. The product surface temperature
rises depending on application conditions, such as the
ambient temperature and the power supply voltage.
Attention must be paid during operation or cleaning.
If the sensing object has a metallic or shiny surface, the E3S-
R may not detect it properly. To avoid this situation, place the
sensing object so that it is not at right angles to the
Photoelectric Sensor.
●Attaching the E39-S Slit
•The Slit can be fitted vertically or horizontally as indicated
by the dotted line. Make sure that Slits for the Emitter and
the Receiver are fitted in the same orientation.
•Place the packing in the supporter and hook the claws on
the indentations in the Sensor head.
•If the supporter is contacting the mounting surface, insert a
spacer to separate it. (Refer to Slit Dimensions.)
•An operating position accuracy of 0.1 mm max. can be
achieved for a Through-beam Sensor without Slits.

General-purpose Sensors
Note:Models numbers for Through-beam Sensors (E3S-@E4, E3S-@E41) 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: E3S-2LE4), the model number of the Receiver, by adding "D"
(example: E3S-2DE4.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.
