Safety precautions
This product is not designed or rated for directly or
indirectly ensuring safety of persons. Do not use it for
such a purpose.
Do not use the product with voltage in excess of the
rated voltage. Excess voltage may result in malfunc-
tion or fire.
Never use the product with an AC power supply.
Otherwise, explostion may result.
When cleaning the product, do not apply a high-pres-
sure spray of water to one part of the product. Other-
wise, parts may become damaged and the degree of
protection may be degraded.
High-temperature environments may result in burn
injury.
The following precautions must be observed to ensure safe
operation of the Sensor.
Operating Environment
Do not use the Sensor in an environment where explosive or
flammable gas is present.
Connecting Connectors
Be sure to hold the connector cover when inserting or removing
the connector. Be sure to tighten the connector lock by hand;
do not use pliers or other tools. If the tightening is insufficient, the
degree of protection will not be maintained and the Sensor may
become loose due to vibration. The appropriate tightening torque
is 0.39 to 0.49 N·m for M12 connectors.
Load
Do not use a load that exceeds the rated load.
Rotation Torque for Sensitivity Adjustment
Adjust with a torque of 0.05 N·m or less.
Environements with Cleaners and Disinfectants
(e.g., Food Processing Lines)
Do not use the Sensor in environments subject to cleaners and
disifectants. They may reduce the degree of protection.
Modifications
Do not attempt to disassemble, repair, or modify the Sensor.
Outdoor Use
Do not use the Sensor in locations subject to direct sunlight.
Cleaning
Do not use thinner, alcohol, or other organic solvents. Otherwise,
the optical properties and degree of protection may be degraded.
Surface Temperature
Burn injury may occur. The Sensor surface temperature rises de-
pending on application conditions, such as the surrounding tem-
perature and the power supply voltage. Use caution when
operating or washing the Sensor.
Do not use the Sensor in any atmosphere or environment that
exceeds the ratings.
Do not install the Sensor in the following locations.
(1)Locations subject to direct sunlight
(2)Locations subject to condensation due to high humidity
(3)Locations subject to corrosive gas
(4)Locations where the Sensor may receive direct vibration or
shock
Connecting and Mounting
(1)The maximum power supply voltage is 30 VDC. Before turning
the power ON, make sure that the power supply voltage does
not exceed the maximum voltage.
(2)Laying Sensor wiring in the same conduit or duct as high-volt-
age wires or power lines may result in malfunction or damage
due to induction. As a general rule, wire the Sensor in a sepa-
rate conduit or use shielded cable.
(3)Use an extension cable with a minimum thickness of 0.3 mm2
and less than 100 m long.
(4)Do not pull on the cable with excessive force.
(5)Pounding the Photoelectric Sensor with a hammer or other
tool during mounting will impair water resistance.
(6)Mount the Sensor using a bracket (sold separately).
Do not exceed a torque of 2.0 Nm when tightening mounting
nuts for plastic models or 20.0 Nm when tightening mounting
nuts for metal models
(7)Be sure to turn OFF the power supply before inserting or re-
moving the connector.
Cleaning
Never use thinner or other solvents. Otherwise, the Sensor sur-
face may be dissolved.
Power Supply
If a commercial switching regulator is used, ground the FG (frame
ground) terminal.
Power Supply Reset Time
The Sensor will be able to detect objects 100 ms after the power
supply is tuned ON. Start using the Sensor 100 ms or more after
turning ON the power supply. If the load and the Sensor are con-
nected to separate power supplies, be sure to turn ON the Sensor
first.
Turning OFF the Power Supply
Output pulses may be generated even when the power supply is
OFF. Therefore, it is recommended to first turn OFF the power
supply for the load or the load line.
Load Short-circuit Protection
This Sensor is equipped with load short-circuit protection, but be
sure to not short circuit the load. Be sure to not use an output cur-
rent flow that exceeds the rated current. If a load short circuit oc-
curs, the output will turn OFF, so check the wiring before turning
ON the power supply again. The short-circuit protection circuit will
be reset.
Water Resistance
Do not use the Sensor in water, rainfall, or outdoors.

Certain Precautions on Specifications and Use
1. 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 Prod-
uct 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 but the following is a
non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety equip-
ment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or prop-
erty. Please know and observe all prohibitions of use applicable to this Prod-
uct.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
3. Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitabil-
ity and does not constitute a warranty. It may represent the result of Omron’s
test conditions, and the user must correlate it to actual application require-
ments. Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial 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.
5. Errors and Omissions. Information presented by Omron Companies has been
checked and is believed to be accurate; however, no responsibility is assumed
