An Impressive Lineup of Sensor Heads to Handle a Wide Variety of Applications
The lineup includes some Sensor Heads as thin
as 3-mm in diameter and others that are thin and
flat. Narrow installation spaces are not a problem
for these models. Still other Sensor Heads are
heat resistant or rated IP67 for superior
environmental resistance. These models are
capable of high-resolution sensing even in harsh
environments.
With flexible cables connecting the Preamplifier to the
Amplifier, installation on moving parts is never a problem.
The twin-output models can also output an open-circuit
alarm. In that rare instance where the cable breaks, the
E2C-EDA can then send out an alarm that greatly simplifies
the task of locating the faulty Sensor.
In addition to repeat accuracy of 1-µm or better, the
temperature characteristics of the E2C-EDA are flat.
This means that environmental factors, such as
temperature swings in the morning and at night, will
not affect high-resolution positioning and screening.

Display reads 1,500 when Fine Positioning
is executed.
The E2C-EDA features two large, easy-to-read digital
displays. Since the digitized detected and threshold values
can be checked at the same time, settings are simple and
reliable for just about anyone. Various teaching methods are
also available for settings that cannot be made consistently
by different operators.
In the stable sensing zone, the E2C-EDA generally
reads 1,500 or higher (see note 2). This way you can tell
at a glance whether the current installation and settings
are within the optimal range.
Note 2: This reading is only a guideline because there may be some variation
between Sensors. Also refer to the Engineering Data because values may
vary with non-standard objects.
A Shielded Connector is used for more
reliable wiring and easier cable handling.
Since the press-fit connector allows repeat
connections, wiring and head replacement
are simple and reliable.
Support for High-resolution Positioning and Screening
Fine Positioning maximizes changes in the digital value as you get closer to
the sensing point. More precise sensing can be achieved by executing Fine
Positioning with the workpiece positioned at the point to be maximized.

The E2C-EDA can visually recognize height and
material differences simply and reliably even with the
most demanding settings.
An OK/NG result is easily obtained because the
E2C-EDA outputs a signal between two threshold
values.
The E2C-EDA has a mutual interference prevention
function that uses intermittent sensing via optical
communications to enable up to 5 Sensors to be
combined very closely together. This feature enables
multiple measurements to be made in a machine or
process.

OMRON's unique wiring-saving Connector
reduces the amount of wiring required even
with a mixture of different sensing types.

High-resolution Digital Proximity Sensor

Position teaching yields consistent settings that cannot
be matched by operator settings.
When using a fixed sensing gap (threshold), the origin
and reference position can be corrected quite simply if
needed, such as when changing the process being
performed.
Simple and Common Sensor Operation in Devices
The basic functions and Programming Devices like the Mobile Console are the same for the
E2C-EDA as they are for the E3X-DA-S Digital Fiber Sensor and the E3C-LDA Laser-type
Photoelectric Sensor. Just select the right type of E2C-EDA for the application, and the rest is easy.

Precautions
!WARNING
Precautions for Correct Use
Do not use this product in operating atmospheres or environments
outside the specified ratings.
Amplifier Units
●Design
Power ON
The Sensor is ready to sense an object within 200 ms after turning
the power ON. If the load and Sensor are connected to different
power supplies, always turn ON the Sensor power first.
●Connecting Sensor Heads
Connecting and Disconnecting Sensor Heads
1. Open the protective cover.
2. Making sure that the lock button is up, insert the fibers all the way
to the back of the Connector insertion opening.
To disconnect the Sensor Head, pull out the fibers while pressing on
the lock button.
Connecting and Disconnecting Connectors
Connecting Connectors
1. Insert the Master or Slave Connector into the Amplifier Unit until it
clicks into place.
2. Apply the supplied seal to the non-connection surface of the Mas-
ter/Slave Connector.
Note: Apply the seal to the grooved side.
Disconnecting Connectors
1. Slide the Slave Amplifier Unit.
2. After the Amplifier Unit has been separated, press down on the
lever on the Connector and remove it. (Do not attempt to remove
Connectors without separating them from other Amplifier Units
first.)
Installing and Removing Amplifier Units
Installing Amplifier Units
1. Install the Units one by one to the DIN rail.
2. Slide one Unit toward the other, match the clips at the front ends,
and then bring them together until they “click.”
Removing Amplifier Units
Slide one Unit away from the other and remove them one by one.
(Do not remove the connected Units together from the DIN rail.)
End Plate Mounting (PFP-M)
Mount End Plates on Amplifier Units to avoid movement due to
vibration. When a Mobile Console is installed, mount the End Plate
facing as shown in the following diagram.
Do not use this product in any safety device used for the
protection of human lives.

Note 1. When the Amplifier Units are connected to each other, the
operable ambient temperature changes depending on the
number of connected Amplifier Units. Check Specifications.
2. Before connecting or disconnecting the Units, always switch
power OFF.

Mounting a Communications Head for the Mobile
Console
Leave a space of at least 20 mm on the left side of the Units for a
Mobile Console Communications Head.
EEPROM Write Error
If the data is not written to the EEPROM correctly due to a power
failure or static-electric noise, initialize the settings using the keys on
the Amplifier Unit.
Optical Communications
When using more than one Amplifier Unit, mount the Units side-by-
side. Do not slide or remove Units while they are in use.
●Miscellaneous
Protective Cover
Be sure to put on the Protective Cover before use.
Mobile Console
Use the E3X-MC11-SV2 Mobile Console for E2C-EDA-series
Amplifier Units. Other Mobile Consoles, such as the E3X-MC11,
cannot be used.
Sensor Head and Amplifier Unit Connection
Be sure to use only specified Sensor Head and Amplifier Unit
combinations. The E3C-LDA-series Photoelectric Sensor with
Separate Digital Amplifier is not compatible, and the E2C-EDA must
not be used with products from that series.
Warm-up
The digital display will slowly change until the circuits stabilize after
the power is turned ON. It takes about 30 minutes after the power is
turned ON before the E2C-EDA is ready to sense.
Maintenance Inspection
•Be sure to turn OFF the power before adjusting, connecting, or
disconnecting the Sensor Head.
•Do not use thinner, benzene, acetone, or kerosene to clean the
Sensor Head or Amplifier Unit.
Sensor Heads
●Mounting
Mounting Sensor Heads
•Use the dimensions from the following table to mount unthreaded
cylindrical models (E2C-ED-@@). Do not tighten screws with
torque exceeding 0.2 N·m when mounting Sensor Heads.
•Use the torque given in the following table to tighten threaded
cylindrical models (E2C-EM@@).
•Do not use torque exceeding 0.5 N·m to tighten screws when
mounting flat models (E2C-EV@@).
•Use a bending radius of at least 8 mm for the Sensor Head cable.
•Use only the special extension cable to extend the cable between
the Sensor Head and the Amplifier Unit. Consult your OMRON
representative for details.
Effects of Surrounding Metal
•Provide a minimum distance between the Sensor and the
surrounding metal as shown in the table below.
Effects of Surrounding Metal (Units: mm)
Mutual Interference
•If more than one Sensor Head is installed face to face or in parallel,
make sure that the distances between two Units adjacent to each
other are the same as or larger than the corresponding values
shown in the following table.
•The distance between Sensor Heads may be narrower than
specified with these Sensors because the Mutual Interference
Prevention Function is used for optical communications between
the Amplifier Units.
