1E3Z Laser Models
Laser Photoelectric Sensor with Built-in Amplifier
E3Z-Laser
Compact
photoelectric sensor
with LASER light
The E3Z LASER sensor in compact
plastic housing features visible LASER
light for precision positioning and detec-
tion applications.
• Visible LASER light for precision posi-
tioning and small object detection
• High power LED for high functional
reserve
Features
Through-beam and Retroreflective Sensors
Greatly Enhanced Beam Visibility for Easier Optical Axis Ad-
justment of Sensors
• The optical design maximizes the linear propagation of la-
ser beams. Red laser beams (class 1) can be precisely
aligned on the targeted position.
• The functional reserve of the rated through-beam sensing
distance of 60 m provides sufficient allowance, enabling
Through-beam Models to be used reliability even in dusty
environments.
Reliable Detection of Small Objects and Narrow Gaps with the
Small Spot
• The spot diameter for Through-beam and Retro-reflective
Models is 5 mm (a typical example at 3 m), making it possi-
ble to detect small workpieces at long distances.
• The sensing distance for Retro-reflective Models is 15 m
(when an E39-R1S Reflector is used). This is the longest
leeway in the industry.
Detect the sides of large tiles.
Count bottles.

2 Laser Photoelectric Sensor with Built-in Amplifier
BGS Models
Long-distance Sensing at 300 mm (White Paper)
A Low Black/White Error for Applications with Mixed Colors
• A black/white error as low as 5% makes detection and op-
eration more stable.
Easy Detection of Small Workpieces and Minor Differences in
Levels with the Small Spot
• Stable detection is possible with no influence from a glossy
background frame.
• The spot diameter for BGS models is 0.5 mm (typical exam-
ple at 300 mm). Combined with an hysteresis of only 5%,
even minute differences can be detected.
• Models with a response time of 0.5 ms (E3Z-LL@3/@8) are
available as standard models for fast-moving objects.
Advanced Optical Technology of the E3Z Laser
Laser beam directional deviation can be suppressed and spot
diameters can be freely customized. This is achieved through
high-precision alignment technology based on LD and emitter
lens modularization. The lens position can be adjusted inline.
(Patent pending.)
Laser Diagram Conceptual Diagram
By precisely adjusting the emitter lens in the vertical, horizon-
tal, and depth directions, alignment can be achieved with min-
imal directional deviation (to ±1 degree).

*1. Pre-wired Models with a 0.5-m cable are also available for these products. When ordering, specify the cable length by adding “0.5M” to the end of the model number
(e.g., E3Z-LT61 0.5M).
M12 Pre-wired Connector Models are also available. When ordering, add “-M1J” to the end of the model number (e.g., E3Z-LT61-M1J). The cable is 0.3 m long.
The following connection forms are also available. Ask your OMRON representative for details.

*2. Consult with your OMRON representative if a distance of more than 10 m is required. Models with large custom-size spots can be produced. These make optical
axis adjustment easier and allow the beam to be received more stably by the Receiver even if vibration is present.

Safety Precautions
Refer to Warranty and Limitations of Liability on page 20.
This product is not designed or rated for ensuring
safety of persons. Do not use it for such purpose.
To ensure safe use of laser products, do not allow
the laser beam to enter your eye. Direct exposure
may adversely affect your eyesight.
Do not connect an AC power supply to the Sensor.
If AC power (100 VAC or more) is supplied to the
Sensor, it may explode or burn.
Be sure to abide by the following precautions for the safe op-
eration of the Sensor.
Operating Environment
Do not use the Sensor in locations with explosive or flamma-
ble gas.
Wiring
Power Supply Voltage and Output Load Power Supply
Voltage
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.
Power Supply Voltage
The maximum power supply voltage is 26.4 VDC. Applying a
voltage exceeding the rated range may damage the Sensor or
cause burning.
Load
Do not use a load that exceeds the rated load.
Load Short-circuiting
Do not short-circuit the load, otherwise the Sensor may be
damaged or it may burn.
Connection without Load
Do not connect the power supply to the Sensor with no load
connected, otherwise the internal elements may explode or
burn. Always connect a load when wiring.
Do not use the product in atmospheres or environments that
exceed product ratings.
Usage Environment
Water Resistance
The Sensor is rated IP67. Do not use it in water, in the rain, or
outdoors.
Ambient Environment
Do not install the product in the following locations. Doing so
may result in product failure or malfunction.
• Locations subject to excess dust and dirt
• Locations subject to direct sunlight
• Locations subject to corrosive gas
• Locations subject to organic solvents
• Locations subject to shock or vibration
• Locations subject to exposure to water, oil, or chemicals
• Locations subject to high humidity or condensation
Designing
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 Sensor with an inverter or servomotor, always
ground the FG (frame ground) and G (ground) terminals, oth-
erwise 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 N·m.

Precautions for Safe Use
Correct Use

13E3Z Laser Models
Metal Connectors
• 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.
• Use a tightening torque of 0.3 to 0.4 N·m for M8 connectors
and 0.4 to 0.5 N·m for M12 connectors. Vibration may
cause the connectors to become loose and reduce the de-
gree or protection is the tightening torque is not sufficient.
Mounting Direction for Distance-settable Models
• 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.
• Do not install the Sensor in the wrong direction. Refer to the
following illustration.
Install the Sensor as shown in the following illustration if each
sensing object greatly differs in color or material.

Indicator Operation
Note: If the stability indicator is lit, the detection/no detection status is stable
within the rated ambient operating temperature (−10 to 55°C).
Inspection and Maintenance
Cleaning
Never use paint thinners or other organic solvents to clean the
surface of the product.
