High Precision Positioning Inductive Proximity Sensor
E2C-EDA
Proximity Sensor with Separate
Amplifier Enables Easily Making High-
precision Sensitivity Settings.
• Wide variety of Sensor Heads to select according to the
application. Flexible cab les are used between Preamplifiers
and Amplifier Units of the Sensor Head s.
• High resistance to changes in ambient temperature.
Temperature characteristics of 0.08%/
°
C (for 5.4-dia. models).
• Make simple and reliable detection settings with micron-level
precision using the teachi ng function.
• Check the sensing excess gain level on the digital display.
• Support for high-precision positioning and screening with
fine positioning to maximize variations.
• The E2C-EDA0 supports an EtherCAT Sensor
Communications Unit or CompoNet Sensor
Communications Unit.

Rating and Specifications
Sensor Heads
*1 The repeat accuracy and temperature characteristic are for a standard sensing object positioned midway through the rated sensing distance.
*2 A sudden temperature rise even within the rated temperature range may degrade characteristics.
*3 For the Sensor Head only without the preamplifier (−10 to 60°C). With no icing or condensation.
*4 Do not operate in areas exposed to water vapor because the enclosure is not waterproof.

Safety Precautions
Refer to Warranty and Limitations of Liability.
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.
Cable
Use an external power cable of cross-section of 0.3 mm2 or more for
the Amplifier, and the total length of the cable must be 30 m or less.
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 Wire-saving 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
Master/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.)
WARNING
Do not use this product in any safety device used for the
protection of human lives.
Precautions for Correct Use

Lock button
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 page 5 in
Rating and Specifications.
2. Before connecting or disconnecting the Units, always
switch power OFF.

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.
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.
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 be tween Sensor Heads may be narrower tha n specified with
these Sensors because the Mutual Interference Prevention Function is
used for optic al communications between the Amplifier Units.
Mutual Interference (Units: mm)
*Mutual interference does not occur for close-proximity mounting
when the Mutual Interference Prevention Function is effective.

Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
PERFORMANCE DATA
Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the
result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.
