E3G-L1
OMRON's unique Hyper LED achieves a pin-
The E3G-L1 is 2.6 times more stable than
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.
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.)
The clearly visible spot makes it easy to check the optical axis
adjustment and sensing position.

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.

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.

Safety Precautions
WANINNG
This product is not designed or rated for
ensuring safety of persons. Do not use it for
such purpose.
• 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.
Precautions for Correct Use
Do not use the product in atmospheres or environment that
exceed product ratings.
Sensing
object
● Wiring
Cable
Mirror-like object
The bending radius of the cable must be no smaller than
25 mm.
• Make sure not to install the Sensor in the incorrect direction.
Avoiding Malfunctions
Refer to the following.
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
Sensing
object
• 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.
Sensing
object

Moving
direction
Moving
direction
Moving
direction
Install the Sensor as shown in the following if each sensing
object greatly differs in color or material.
• 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.
Moving direction
Moving direction
● 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
Mounting Directions
Paint thinner will damage the casing of the Sensor. Do not use
paint thinner to clean the Sensor.
• Make sure that the sensing side
of the Sensor is parallel with the
surface of each sensing object.
● Others

EEPROM Writing Error
Do not incline the Sensor
If a teaching data error occurs with the operation indicator

teaching operation of the Sensor again.
towards the sensing object.
Surface of
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.
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.
