E3C-LDA SERIES
Advanced Industrial Automation
long-distance, adjustable laser beam
Photoelectric laser sensors

Omron’s E3C-LDA photoelectric laser sensor series is designed to provide advanced
object detection, positioning and high-resolution sensing. What’s unique about the
E3C-LDA is that the focal point and optical axis on the sensor head can be easily
adjusted for precise beam adjustment, which in turn ensures easy set-up and
very precise operation from a long distance. In addition, the E3C-LDA series offers
multiple separate laser beam types – spot beam, line beam, area beam
and retroreflective - to cover a multitude of applications!
Compact, fast and very accurate!
Its state-of-the-art construction, speed, accuracy and built-in reliability combine
to make this very compact photoelectric sensor series ideal for use in today’s
production processes, where high precision and fast response time are vital.
Typical applications include object detection in the semiconductor industry,
grease, adhesive and seal inspection, assembly oriented applications in the
automotive, pharmaceutical and packaging industries, and sheet
displacement inspection in the paper industry.

E3C-LDA SERIES
Unique!
Adjustable settings for easy mounting and installation
The E3C-LDA is currently the only photoelectric sensor whose
focal point and axis can be easily adjusted to provide optimum
sensing capability. By varying the focal point mechanism
(patent pending) you can adjust the beam diameter to suit the
work-piece. This in turn improves the reliability of detection.
Varying the axis alignment mechanism (patent pending)
enables you to adjust the direction of the beam fan to the
mounting surface. This feature is perfect for accurate, long-
distance positioning applications.
Multiple optical beam shapes to choose from!
With just one sensor head (spot size, E3C-LD11) and two
clip-on units (E39-P11 and E39-P21 lenses) the E3C-LDA series
effectively offers multiple different beam shapes – spot, line,
area beam or retroreflective. The E3C-LD31 unit provides the
area beam, while the E3C-LD21 provides the line beam.
This feature really extends the application possibilities
of the sensor.

Spot size shape
Ideal for detecting minute items like IC-pins and for very
precise positioning.
Line beam shape
Ideal for detecting objects that are not fixed or for inspecting
the completeness of parts. Typical application is edge
control inspection.
Area beam shape
Ideal for printed mark detection or for basic object detection
in the paper and wood industry.
New! Retroreflective beam
This sensor combines high performance with easy installation
and set-up. Using the new MSR sensing principle and small
laser focus adjustment, this sensor achieves sensing distances
of up to 7 metres with high-precision object detection. It is
ideal for object detection through a small hole or gap in the
assembly process. It can also be used for object detection
through a glass view port in environmentally harsh processes.
Conventional principle
In areas where space is limited, the reflection of the object
does not reach the receiver side.
New MSR principle
The E3C-LR enables highly accurate detection, even in a limited
space area. Object detection is possible even through a small
hole or gap, thanks to the coaxial (MSR) sensing principle.
MSR principle

Min. beam spot of 0.8 mm (at 1.000 mm)
Max. sensing distance up to 7 m
This means that the sensor can be located away from moving
parts in a production process and still function with great
precision, so installation is fast and easy.
The retroreflective laser sensor has a sensing distance of up
to 7 metres. It is also highly precise and easy to set up.
Ultra-compact sensor head
The E3C-LD11 sensor head is very compact, which makes
it easier to install and implement in production equipment.
Easy, reliable connection
E-Con* connectors enable fast, easy connection of the E3C-LDA
sensor to the amplifier, using Omron’s Plug & Play concept.
This ensures fast, easy replacement of the sensor head when
required, and easier maintenance. The E-Con connection also
ensures reliable contact between the sensor and amplifier, and
minimises possible mistakes by maintenance staff.
*Connectors comply with E-Con specifications.
Unique!
Sensing distance up to 7 metres!
The E3C-LD sensor heads have a detecting distance of up
to 1000 mm, while the retroreflective E3C-LR sensor heads
a detecting distance of up to 7000 mm by using the reflector.

Large, intelligent dual display
The slim-line amplifier’s easy-to-read display provides a variety

threshold value. Threshold values can be easily set while
checking incident light levels.
Mutual interference prevention
Up to 10 sensors can be combined very closely together
without any mutual interference occurring between them.
With this feature multiple measurements can be made
in a machine or a process.
Timer functions
The E3C-LDA’s amplifier features a variety of timer functions.
It is possible to set up specific times for ON-delay, OFF-delay
and One-shot operation functions. The counter mode counts
objects in a process (count-up and count-down).
Differential output mode
The differential output mode provides stable detection
during counting, and ignores unstable conditions in the
production process.
Power tuning function
Omron’s patented power tuning function provides optimal
light level settings for all connected sensors. With just one
touch you can adjust the light level settings of all connected
amplifiers to the same level. This feature saves you time and
money by eliminating labour-intensive adjustments.
Flexible control
An Omron mobile console (E3X-MC11-S) can be used for
operating the sensor head when a considerable distance
separates the sensor head and amplifier. All parameters and
settings can be set up via this mobile console.**
**Omron’s fibre-optic series E3X-DA-S and E3X-MDA can also be combined
and controlled by this mobile console.
