Features
Simplicity
Omron’s compact E3FA series of photoelectric sensors is simple and quick to mount, as well as easy and intuitive to set-up.
The large and robust adjuster makes life much easier for installers to adjust the sensor, as does the bright, high-power red LED, which is clearly
visible for easy alignment, even over longer distances. Similarly, the sensor’s LED status indicator can be viewed from long distances and wide
angles.
Compact size and shape. Can be in-
stalled almost anywhere.
Visible LED light for easy alignment.
Bright LED indicators for the easy
operational status checking.
Flush mounting option for smooth in-
stallation.
One family for all
Typically installed in industrial plants ranging
from food and beverage, textiles, ceramics
and brick production, through to logistics,
there’s always an E3FA model to fit your
application.
This extensive photoelectric sensor series
with high reliability and enhanced
performance includes through-beam,
retroreflective and diffuse-reflective types in
straight and radial versions. Straight versions
are also available with background-
suppression, limited-reflective detection, and
transparent object detection types for special
applications.
Application specific models
Limited-reflective types suitable
for detecting transparant film to
shiny, mirror film.
Transparent object detection
types utilising Omron’s unique
technology for detecting objects
with birefringent (double refrac-
tion) properties.
Background suppression types
for the stable detection of differ-
ent objects with various colours.
Non-stop detection
Especially designed for machines that never stop, the rugged E3FA series offers completely reliable sensing in a robust and waterproof housing
that can withstand even high-pressure cleaning. Exceeding market standards, this series also has high EMC protection and light immunity. In
addition, there is the added benefit of the high-power LED, which contributes to high sensing stability even in environments with dust or vibrations.
