A-44 Standard Photoelectric Sensors
E3Z-series reliability
covers a wide range
of object/background
combinations,
so ensuring stable
detection regardless
of workpiece color or
reflectivity.
Photoelectric Sensor
with Built-in Amplifier
E3Z is environmental-friendly, energy-saving.
10-quantity packing reduces waste cartons. Packed in "combustible" polyethylene bags
free of Styrofoam. *
Standard models provided with a 0.5-m cable are
available for the elimination of unnecessary ca-
ble length.
On-going elimination of materials containing
lead.

A-45E3Z
E3Z
Ideal for detecting
small objects with a
small spot:
●Tiny objects as little as
0.1 mm in diameter can
be detected with its 2.5-
mm dia. spot.
●The thin beam enables
detection through gaps
or small holes.
●The high-intensity spot
of light enables visual
alignment of sensing
spot position.
Stable detection of
recyclable thin-wall
PET bottles.
Standard-size trans-
parent object sensor
●Uses OMRON's unique
optical system ("Inner
View") that can detect
various shapes of PET
bottles and transparent
objects.
●Detects a wide range of
bottles regardless of size
and facets
Fork design
eliminates the need
for optical axis
adjustment.
●Two-axis models also
available.
●Ideal for limit of travel
monitoring.
●Condition monitoring.
●„Flag“ identification.

Mounting method
1. Hook the upper protruding
portions of the Slit to the up-
per indented mounting por-
tion of the Sensor and
adjust the position of the
Slit so that the Slit will be
parallel to the lens surface.
2. Press the lower protruding
portion of the Slit onto the
indented mounting portion
of the Sensor until the Slit
snaps in.

Demounting method
1. Press the upper portion of
the Slit.
2. Disconnect the lower pro-
truding portion of the Slit
from the Sensor and re-
move the Slit.

Simple Detection of Glossy, Uneven Objects
BGS
(Background Suppression)
Objects beyond the set distan-
ce, such as the conveyor, will
not be detected. The hystere-
sis is 10% or less, so at a set
distance of 40 mm, steps with
a thickness of 4 mm can be de-
tected on objects.
Selectable by Changing Cable Connection
Distance threshold
ON (incident)
OFF (interrupted)
Conveyor (background)
(for Light-ON setting)
FGS
(Foreground Suppression)
Glossy, uneven objects are re-
liably detected because the
OFF (incident) status occurs
only when the conveyor is de-
tected, and ON (interrupted)
status occurs only when an ob-
ject exists or when reflected
light is not returned to the Sen-
sor. (Depending on the shape
of the object, an OFF-delay
timer may be required.)

A-62 Standard Photoelectric Sensors
Precautions
Do not connect an AC power supply to the Sensor. If AC pow-
er (100 VAC or more) is supplied to the Sensor, it may ex-
plode or burn.
Be sure to abide by the following precautions for the safe op-
eration of the Sensor.
Wiring
Power Supply Voltage and Output Load Power Supply Volt-
age
Make sure that the power supply to the Sensor is within the
rated voltage range. If a voltage exceeding the rated voltage
range is supplied to the Sensor, it may explode or burn.
Load Short-circuiting
Do not short-circuit the load, otherwise the Sensor may be
damaged.
Connection without Load
Do not connect the power supply to the Sensor with no load
connected, otherwise the internal elements may explode or
burn.
Operating Environment
Do not use the Sensor in locations with explosive or flamma-
ble gas.
Design
Power Reset Time
The Sensor is ready to operate 100 ms after the Sensor is
turned ON. If the load and Sensor are connected to indepen-
dent power supplies respectively, be sure to turn ON the Sen-
sor before supplying power to the load.
Wiring
Avoiding Malfunctions
If using the Photoelectric Sensor with an inverter or servomo-
tor, always ground the FG (frame ground) and G (ground) ter-
minals, otherwise the Sensor may malfunction.
Mounting
Mounting the Sensor
• If Sensors are mounted face-to-face, make sure that the op-
tical axes are not in opposition to each other. Otherwise,
mutual interference may result.
• Always install the Sensor carefully so that the aperture an-
gle range of the Sensor will not cause it to be directly ex-
posed 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 lose its water-resistive 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 Nm.
M8 Connector
• Always turn OFF the power supply to the Sensor before
connecting or disconnecting the metal connector.
• Hold the connector cover to connect or disconnect it.
• Secure the connector cover by hand. Do not use pliers, oth-
erwise the connector may be damaged.
• If the connector is not connected securely, it may be discon-
nected by vibration or the proper degree of protection of the
Sensor may not be maintained.
Distance setting models E3Z-LS
• Make sure that the sensing side of the Sensor is parallel
with the surface of the sensing objects. Normally, do not in-
cline the Sensor towards the sensing object.
If the sensing object has a glossy surface, however, incline
the Sensor by 5° to 10° as shown in the illustration, provided
that the Sensor is not influenced by background objects.
• If there is a mirror-like object below the Sensor, the Sensor
may not operate stably. Therefore, incline the Sensor or
separate the Sensor from the mirror-like object as shown
below.
