CSM_E3Z_DS_E_18_4
Compact Photoelectric Sensor with Built-in Amplifier
E3Z
The Standard for Photoelectric Sensors
with a Secure Track Record of One
Million Sold Yearly.
• Long sensing distance of 30 m for Through-beam Models, 4 m for
Retro-reflective Models, and 1 m for Diffuse-reflective Models.
• Mechanical axis and optical axis offset of less than ±2.5° simplifies
optical axis adjustment.
• High stability with unique algorithm that prevents interference of
external light.
Be sure to read Safety Precautions on
page 13.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Features
Industry's Top-level Sensing Distance with
Built-in Amplifier
A separately sold filter is available to prevent mutual interference for
Through-beam Models with red lights sources and a sensing
distance of 10 m. Reflective Models include functionality to prevent
mutual interference (up to 2 sensors).
Long-distance, Through-beam Sensors with a detection distance of
30 m (response time: 2 ms) are also available.
Low-temperature Operation for Applications in Cold-storage Warehouses
A wider ambient operating range from −40 to 55°C (main models with connectors). We also provide Sensor I/O Connectors with PUR Cables for
high resistance to cold environments.
Improved Matching of Optical Axis and Mechanical Axis for
Through-beam Models and Retro-reflective Models
The offset between the optical axis and the mechanical axis is kept within ±2.5°, so the optical axis can
be accurately set simply by mounting the Sensor according to the mechanical axis.
Sensor Protection against Incorrect Wiring
The Sensor includes output reverse polarity protection.
(A diode to protect against reverse polarity is added to the output line.)
Complete Compliance with the EU's RoHS Directive
Lead, mercury, cadmium hexachrome, polybrominated biphenyl (PBB), and polybrominated
diphenyl ether (PBDE) have all been eliminated. Also, burnable polyethylene packaging has
been used.

Slit (A Slit is not provided with Through-beam Sensors) Order a Slit separately if required. [Refer to Dimensions on page 16.]
Reflectors
(Reflector required for Retroreflective Sensors) A Reflector is not provided with the Sensor. Be sure to order a Reflector separately.
[Refer to Dimensions on E39-L/E39-S/E39-R]
Note: 1. If you use the Reflector at any distance other than the rated distance, make sure that the stability indicator lights properly when you install the Sensor.

* The ambient temperature range during operation for connector models depends on the model. For the E3Z-T66/T86/R66/R86, the range is −40°C to 55°C. For the
E3Z-D66/D86/D67/D87, the range is −30°C to 55°C. For other connector models, the range is −25°C to −55°C.
The sensing distance for Retro-reflective Models (E3Z-R66/R86) between −40°C to −25°C, however, will be as follows (not the values in the table):
With E39-R1S: 3 m (100 mm), With E39-R1: 2 m (100 mm).
Also, use the XS3F-M42@-4@@-L Sensor I/O Connector (PUR cable) for applications between −25°C to −40°C. (Refer to page 4.)

* Models numbers for Through-beam Sensors (E3Z-T@@) are for sets that include both the Emitter and Receiver.
The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3Z-T61-L 2M), the model number of the Receiver, by adding "-D"
(example: E3Z-T61-D 2M.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.

Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Do not use the product in atmospheres or environments that exceed
product ratings.
● Wiring
M8 Metal Connector
•Be sure to connect or disconnect the metal connector after turning
OFF the Sensor.
•Hold the connector cover to connect or disconnect the metal
connector.
•Secure the connector cover by hand. Do not use any pliers,
otherwise the connector may be damaged.
•The proper tightening torque range is between 0.3 and 0.4 N·m. Be
sure to tighten the connector securely, otherwise the specified
degree of protection may not be maintained or the connector may
be disconnected due to vibration.
● Mounting
Sensor Mounting
Use M3 screws to mount the sensor and tighten each screw to a
maximum torque of 0.53 N·m.
● Oil-resistant Models
Oil Resistance
•Although the E3Z-@@@K Sensors have oil-resistant specifications,
performance may be affected by certain types of oil. Refer to the
following table.
•E3Z-@@@K Sensors are tested for resistance to the oils given in
the following table. Refer to the information in the table when
deciding which type of oil to use.
Note: 1. The E3Z maintained a minimum insulation resistance of 100 MΩ after
it was dipped in all the above oils for 240 hours.
2. When using the Sensors in environments subject to oils other than
those listed above, use the figures for kinematic viscosity and pH from
the table as general guidelines. Additives and other substances
contained in oils may affect the E3Z. Be sure to consider this before
use.

replacement thereof) the non-complying Product, (ii) repair the non-complying Product, or (iii) repay or credit Buyer an amount
equal to the purchase price of the non-complying Product; provided that in no event shall Omron be responsible for warranty,

were properly handled, stored, installed and maintained and not subject to contamination, abuse, misuse or inappropriate
modification. Return of any Products by Buyer must be approved in writing by Omron before shipment. Omron Companies shall
not be liable for the suitability or unsuitability or the results from the use of Products in combination with any electrical or

Suitability of Use.
Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the
combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable
third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself
is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine,
system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product
with respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases.

it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
Change in Specifications.
Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our
practice to change part numbers when published ratings or features are changed, or when significant construction changes are
made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers
may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at
any time to confirm actual specifications of purchased Product.

assumed for clerical, typographical or proofreading errors or omissions.
