Adjustment Method 1
Use this method if the sensing object is more reflective than
the background.

Distance adjuster
Sensing object
Distance adjuster
*
Align the distance adjustment scale
with the groove on the 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 A
(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.
Center
Background
object
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.

WARNING
This product is not designed or rated for
ensuring safety of persons.
Do not use it for such purposes.
Type
Precautions for Correct Use
Do not use the product in atmospheres or environments that
exceed product ratings.
If the sensing object has a metallic or shiny surface, the E3SR 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.

Note 1. Only C42 models with die-cast cases are available.
2. The Emitter for a Through-beam C4-type Sensor is the same as the
Emitter for an E4-type Sensor. (E.g., E3S-5LE4)
3. When a C- or B- type Sensor experiences a load short-circuit or overload,
the output transistor will be turned OFF. Check the load conditions before
turning the power back ON.

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.

Note: The dimensions in parentheses are for when the Spacer is not used.
* With the E3S-2E4 (41), use the Spacer as shown in the figure above so that the supporter
and Mounting Bracket will not be struck when the optical axis is adjusted.
With the E3S-5E4 (41), the Spacer is not particularly required. Use the Spacer, however, to directly mount both the E3S-2E4 (41) and -5E4 (41).

combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable
third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself

Change in Specifications.
Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our
