1. Do not use the product in an environment where flammable or
explosive gas is present.
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 damage or burnout.
4. Be sure that the power supply polarity and other wiring is correct.
Incorrect wiring may cause explosion or burnout.
5. If the power supply is connected directly without a load, the
internal elements may explode or burn. Be sure to insert a load
when connecting the power supply.

● Operating Environment
1. Do not install the product in the following locations.
Doing so may result in product failure or malfunction.
(1) Outdoor locations directly subject to sunlight, rain, snow, water
droplets, or oil.
(2) Locations subject to atmospheres with chemical vapors, in
particular 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. The following conditions shall be observed if you use the product
under an environment using cutting oil that may affect product’s
life and/or performance.
• Usage under the cutting oil condition designated by the
specification
• Usage under the cutting oil dilution ratio recommended by its
manufacturer
• Usage in oil or water is prohibited
Impact on the product life may differ depending on the oil you use.
Before using the cutting oil, make sure that it should not cause
deterioration or degradation of sealing components.
