Omron E3Z-LASER DATASHEET
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 Adjustment of Sensors
• The optical design maximizes the linear propagation of laser 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.
Detect the sides of large tiles.
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 possible 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.

Long-distance Sensing at 300 mm (White Paper)
Detect chip components on tape.
A Low Black/White Error for Applications with Mixed Colors
• A black/white error as low as 5% makes detection and operation more stable.
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.

Laser Diagram Conceptual Diagram
By precisely adjusting the emitter lens in the vertical, horizontal, and depth directions, alignment can be achieved with minimal directional deviation (to ±1 degree).
Detect protruding straws.
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 example 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.

*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.
Pre-wired Models with 1-m or 5-m cables
Pre-wired Connector Models with M8 4-pin connectors, M8 3-pin connectors.
*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.
*3. The Reflector is sold separately. Select the Reflector model most suited to the application.
*4. Values in parentheses indicate the minimum required distance between the Sensor and Reflector.
