Safety Precautions
Refer to Warranty and Limitations of Liability for detailed precautions.
WARNING
This product is not designed or rated for
ensuring safety of persons either directly or
indirectly. Do not use it for such purposes.
Never use this product with an AC power
supply.
Otherwise, explosion may result.
● Design
Influence of Surrounding Metal
When mounting the Sensor within a metal panel, ensure that
the clearances given in the following table are maintained.
l
The following precautions must be observed to ensure safe
operation.
(1) Do not use the Sensor in an environment where
inflammable or explosive gas is present.
(2) Do not attempt to disassemble, repair, or modify any
Sensors.
(3) Power Supply Voltage
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) Incorrect Wiring
Be sure that the power supply polarity and other wiring is
correct. Incorrect wiring may cause explosion or fire.
(5) Connection without a Load
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.
(6) This Sensor received UL Standard certification under the
assumption that the Sensor will be used in a Class 2
circuit. When using the Sensor in the United States or
Canada, be sure to use it in a Class 2 circuit.

Do not use this product under ambient conditions that exceed
the ratings.
(1) Do not use the Sensor in the following locations.
1. Outdoor locations directly subject to sunlight, rain,
snow, or water droplets
2. Locations subject to atmospheres with chemical
vapors, in particular solvents and acids
3. Locations subject to corrosive gas
(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. Refer to the
Technical Guide Photoelectric Sensors for typical
measures.
(3) Laying the 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) Cleaning
Never use thinner or other solvents. Otherwise, the
Sensor surface may be dissolved.
