E3NT-L
Distance-Setting
Photoelectric Sensor
Advanced Industrial Automation

Omron’s E3NT- is a distance-setting photoelectric sensor whose
ease-of-use, robustness and intelligence make it one of the most
advanced sensors on the market. The E3NT- has a detection range
of up to 2000mm, and features background and foreground
suppression. Its patented optic design enables this innovative
sensor to reliably detect objects regardless of their direction.
One of the most advanced
sensors in the world
It is teachable and can be operated via just three keys. It is fully
digital for stable, reliable information, and can be adapted to
operate in the harshest of environments. These features
make the E3NT- suitable for applications in the material
warehousing and food processing industries, where
long yet precise distance sensing is required.

Built for every environment
The E3NT- is a sealed unit. Its robust aluminium
housing and smooth body design prevents dirt
from easily attaching to it. This makes the E3NT-
ideal for use in the food processing industry.
An optional coating enables it to operate in
environmentally aggressive conditions, and an
anti-condensation option with heated glass
window enables it to cope in very low
temperature environments.
Patented optic design for reliable sensing
The E3NT- sensor’s optics are specially arranged so that
distance is evaluated using the ‘double triangulation’
principle. This patented optic design enables the E3NT- to
reliably detect objects regardless of their direction. It also
enables the rotary position of the E3NT- to be selected freely
about its optical axis, which makes this sensor ideal for multi-
axis handling equipment. The E3NT- ’s background and
foreground suppression features means that objects are
detected only within the predefined sensing zone. Objects in
the background or foreground of that zone are ignored.
‘Teach & play’ manually…
Setting up the E3NT- is fast and easy via external
pushbuttons. Its ‘teach & play’ design concept enables you to
teach the sensor the distance of the detectable object simply
by pressing one push-button. The built-in 3 pushbutton
keypad and a 4-digit display enable you to set and monitor
parameters via a user-friendly menu. The display provides
direct verification of the setting result, and it enables a
relatively deep menu structure to be implemented into
the sensor.
…Or via computer!
The E3NT- can also be remotely configured using Omron’s
PC configuration Sensor Support Software package, whose
features include teaching, operation and mode set-up,
I/O configuration and distance monitoring via a trend graph.
This software not only saves you configuration time, it also
makes field exchange, firmware upgrading and remote
trouble-shooting easy.

Intelligence built-in
The E3NT- is intelligent: one programmable input and two
programmable outputs, all configured by software as PNP or
NPN, provide the utmost flexibility. The programmable input
can be set as a teach-in or program lock. The programmable
outputs can be adjusted to different set points (shelf
replenishment control is just one of many examples), alarm
output, self test etc., which means that the E3NT- can replace
two sensors. An analogue version of the E3NT- is also
available and comes with a full range of linear analogue
outputs, making it ideal for unwinding applications.
Accessories for enhanced operation
Multi-purpose bracket
Omron’s specially designed multi-purpose bracket enables the
E3NT- to be installed in a wide variety of positional choices for
optimal sensing performance.
Optical link adapter
Omron’s E3NT-A 232 optical link adapter clips to fit the E3NT
sensor’s communication head for connector-less data transfer
between the sensor and your PC. This is ideal when the E3NT-
is installed in an area where access is restricted. Via this link
and your PC you can continuously monitor the sensor’s
operation from the comfort of a remote area.
Sensor Support Software (S3)
With Omron’s Sensor Support Software (S3) package you can
enjoy the benefits of copying multiple customised sensor
settings, monitoring for more detailed analysis, setting up
parameters much more easily, and tracing.

Miss operation zone

Thanks to the optic
link, the sensor can
be remotely set and
checked while it is
operating in an area
where access is
restricted
Two outputs can
distinguish whether
there is one, two or
even more pallets in
the storage location
The E3NT-L can check
if there is shelf-space
free for a pallet
Machines in the food
industry need to be
cleaned fre uently.
With rapid temperature
changes, and lots of
water and steam,
a completely sealed
sensor with window
heating is essential
This robust sensor
is ideal for operation
in the harshest of
environments
A version of the
E3NT-L with analogue
output is available,
making it ideal for
winding/unwinding
applications
