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.

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.

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.

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.

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.
