High-resolution Sensing with Unprecedented Ease
Sensors
An Impressive Lineup of Sensor Heads to Handle a Wide Variety of Applications
Industry First
An Array of Heads
Flexible Cables Provided as a Standard Feature
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.

High-resolution Sensing Unaffected by Environmental Swings

Sensing distance (mm)
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.

Two Clear, Large, and Easy-to-Read Digital Displays
Digital Display Simplifies Installation and Settings
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.
Detected value Threshold value
Character size: 6 mm
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.
Threshold Teaching
MODE Key
(See note 1.)
UP/DOWN Keys
for fine threshold value adjustments
Note 1: Press the MODE Key with the E3C-EDA running to switch to individual teaching modes,
Fine Positioning, or Zero Reset.
Connector for Connecting
Sensor Heads to Amplifiers
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.

Fine Positioning Maximizes Digital Changes
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.

Mutual Interference Prevention
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.

Simple and Common Sensor Operation in Devices
Platform Concept Ensures Common Operation and Programming 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
Disconnecting Connectors
!WARNING
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.)
Do not use this product in any safety device used for the
protection of human lives.
Precautions for Correct Use
Press down.

Installing Amplifier Units
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.
1. Install the Units one by one to the DIN rail.

1. Open the protective cover.
2. Making sure that the lock button is up, insert the fibers all the way

Removing Amplifier Units
Lock button
Slide one Unit away from the other and remove them one by one.
(Do not remove the connected Units together from the DIN rail.)
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.
Connecting and Disconnecting Connectors
End Plate Mounting (PFP-M)
Connecting Connectors
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.
1. Insert the Master or Slave Connector into the Amplifier Unit until it
clicks into place.

• 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.
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.
Effects of Surrounding Metal
• Provide a minimum distance between the Sensor and the
surrounding metal as shown in the table below.

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.
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
