Safety Precautions

Be sure to read the precautions for all models in the website at: http://www.automation.omron.com/.

Warning Indications

Meaning of Product Safety Symbols

This product is not designed or rated for ensuring

safety of persons either directly or indirectly.

Do not use it for such purposes.

Otherwise, explosion may result.

Never use the product with an AC power supply.

The following precautions must be observed to ensure safe operation.

1. Do not use the product in environments subject to flammable or

explosive gases.

2. Do not attempt to disassemble, repair, or modify the product.

3. Do not use a voltage that exceeds the rated operating voltage

range.

Applying a voltage that is higher than the operating voltage range

may result in explosion or fire.

4. Be sure that the power supply polarity and other wiring is correct.

Incorrect wiring may cause explosion or fire.

5. If the power supply is connected directly without a load, the

internal elements may explode or burn.

6. Dispose of the product according to applicable regulations (laws).

Do not use the product in any atmosphere or environment that

exceeds the ratings.

Operating Environment

1. Do not install the Sensor in the following locations.

(1) Outdoor locations directly subject to sunlight, rain, snow,

waterdroplets, or oil.

(2) Locations subject to atmospheres with chemical vapors,

inparticular solvents and acids.

(3) Locations subject to corrosive gases.

2. The Sensor may malfunction if used near ultrasonic cleaning

equipment, high-frequency equipment, transceivers, cellular

phones, inverters, or other devices that generate a high-frequency

electric field. Please refer to the Precautions for Correct Use on

the OMRON website (www.ia.omron.com) for typical measures.

3. Laying the Proximity Sensor wiring in the same conduit or duct as

high-voltage wires or power lines may result in incorrect operation

and damage due to induction. Wire the Sensor using a separate

conduit or independent conduit.

4. Never use thinner or other solvents. Otherwise, the Sensor

surface may be dissolved.

5. When turning on the power by influence of temperature

environment, an outputmis-pulse sometimes occurs. After the

sensor has passed for 300 msec after turning on, please use in the

stable state.

6. The sensor is adjusted with a high degree of accuracy, so do not

use in the environment with sudden temperature change.

7. Operation check is performed using an OMRON's IO-Link master.

If using an IO-Link master from another company, perform the

operation check in advance.

8. When connecting non IO-Link compliant models to the IO-Link

master, use the SIO mode.

9. In the IO-Link mode, the cord between the IO-Link master and

sensor must have a length of 20 m or less.

10.The Sensor cannot be used embedded in where pressure is

constantly applied to the sensing surface, such as hydraulic

cylinders and hydraulic valves.

Warning level

Indicates a potentially hazardous situation

which, if not avoided, will result in minor or

moderate injury, or may result in serious

injury or death. Additionally there may be
