Distance-setting Photoelectric Sensor
E3G-L1/L3
Effectively Cuts the Influence of
Workpiece Characteristics, Such as
Gloss, Incline, and Color.

on page 12.
Features
A 1-mm-dia. Pin-point Beam
Allows Detection of Minute Objects
E3G-L1
OMRON's unique Hyper LED achieves a pin-
point light source only 1/7 the size of conventional light
sources, with uniform light-intensity distribution. The Hyper
LED achieves stable detection of small objects by eliminating
the dead band that results from the drop-out that commonly
occurs at the center of conventional LEDs.
The clearly visible spot makes it easy to check the optical axis
adjustment and sensing position.
Stable Detection Based Not Only
on Object Color, But Also on
Inclination and Glossiness
The E3G-L1 is 2.6 times more stable than
previous models with inclination characteristics.
The use of the shine-proof optical system with conventional
triangulation reduces the discrepancies in sensing distance
due to object color, surface, and inclination.
(The E3G-L3 is 2.2 times more stable than previous models.)

Shine-proof Optical System
(E3G-L1, E3G-L3)
Previous Distance-
setting Models
A low-error distance signal is assured
because an image is formed on the
photosensing device (PSD),
irrespective of the sensing distance.
Detection is also stable with respect to
the inclination of the object.
At some distances, images cannot
be formed on the photosensing
device (PSD). The spot diameter is
large, distance errors occur due to
displacement of the center of
gravity, and detection is unstable
with respect to the inclination of the
object.

Simple Detection of Glossy,
Uneven Objects
Optimal Background and Conveyor
Teaching.
Double-bar Display Shows Excess Gain at a
Glance.
The Sensor features one-
touch teaching settings. After
the workpiece, background,
and conveyor teaching are
complete, fine adjustment of
the sensitivity can be made in
13 levels for Normal Mode or 5
levels for Zone Mode.
The excess gain in distance or
detecting of small steps can be
easily set.
A Lineup of M8
Connectors
Easy to disconnect, making
maintenance simple.
Meets the Needs of All Industries, Including Semiconductors, Electronic Components, Food,
and Packaging
Triangulation with hysteresis of 4%
or less (E3G-L1) is used, so objects
beyond the set distance are not
detected.
At a set distance of 30 mm, steps that
are 1.2 mm high can be detected.
Glossy, uneven objects are reliably
detected because OFF (light) status
occurs only when the conveyor is
detected, and ON (dark) status
occurs when an object is present.

Adjustment Procedure
Distance Setting (Teaching)
Select the most appropriate teaching method in reference to the following descriptions.
La: Distance equivalent to threshold (a)
Lb: Distance equivalent to threshold (b)
The following settings are also possible:
Setting the maximum sensing distance of the Sensor: Maximum distance setting.
Setting the minimum differential travel of the Sensor: Minimum distance setting.
Distance from Sensor to background must not exceed the values shown below during normal one-point or zone one-point
teaching.
Maximum sensing distance of the E3G-L3@ may differ depending on the color of the sensing object when setting distance is
more than 150 mm. Confirm the operation of the Sensor before actual operation.
Step Operation
1Install, wire, and turn ON the Sensor.
2Perform distance setting (teaching). Refer to Distance Setting (Teaching), below.
3Make a fine adjustment of the threshold, if necessary. Refer to Manual Teaching (Fine Distance Setting). Page 11
4Check that the mode selector switch is set to .

Safety Precautions
This product is not designed or rated for
ensuring safety of persons. Do not use it for
such purpose.
Do not use the product in atmospheres or environment that
exceed product ratings.
Wiring
Cable
The bending radius of the cable must be no smaller than
25 mm.
Avoiding Malfunctions
If using the Photoelectric Sensor with an inverter or
servomotor, be sure to ground the FG (frame ground) and G
(ground) terminals, otherwise the Sensor may malfunction.
Mounting
Mounting Conditions
If Sensors are mounted face-to-face, make sure that no
optical axes cross each other. Otherwise, mutual
interference may result.
Be sure to install the Sensor carefully so that the directional
angle range of the Sensor will not be directly exposed to
intensive light, such as sunlight, fluorescent light, or
incandescent light.
Do not strike the Photoelectric Sensor with a hammer or any
other tool during the installation of the Sensor, or the Sensor
will loose its water-resistant properties.
Use M3 screws to mount the Sensor.
When mounting the case, make sure that the tightening
torque applied to each screw does not exceed 0.54 N·m.
M8 Connector
Always turn OFF the Sensor before connecting or
disconnecting the M8 connector.
Be sure to hold the connector cover when connecting or
disconnecting the M8 connector.
Secure the M8 connector by hand. Do not use any pliers,
otherwise the connector may be damaged.
If the M8 connector is not connected securely, the M8
connector may be disconnected by vibration or the proper
degree of protection of the Sensor may not be maintained.
Mounting Directions
Make sure that the sensing side
of the Sensor is parallel with the
surface of each sensing object.
Do not incline the Sensor
towards the sensing object.
If the sensing object has a glossy
surface, incline the Sensor by 5°
to 10° as shown below, provided
that the Sensor is not influenced
by any background objects.
If there is a mirror-like object below the Sensor, the Sensor
may not be in stable operation. Therefore, incline the
Sensor or keep the Sensor a distance away from the mirror-
like object as shown below.
Make sure not to install the Sensor in the incorrect direction.
Refer to the following.
Install the Sensor as shown in the following if each sensing
object greatly differs in color or material.
Adjustments
If the Sensor is not in stable operation due to color
differences, make a fine adjustment of the threshold level and
confirm that Sensor operation is stable. Refer to Manual
Teaching (Fine Distance Setting) Page 11
Maintenance and Inspection
Cleaning
Paint thinner will damage the casing of the Sensor. Do not use
paint thinner to clean the Sensor.
Others
EEPROM Writing Error
If a teaching data error occurs with the operation indicator
flashing due to a power failure or static noise, perform the
teaching operation of the Sensor again.
Water Resistivity
To ensure the water resistivity of the Sensor, tighten the
screws of the operation panel cover to a torque of 0.2 to
0.3 N·m.
