Safety Precautions

Refer to Warranty and Limitations of Liability.

This product is not designed or rated for ensuring

safety of persons. Do not use it for such purpose.

To ensure safe use of laser products, do not allow the

laser beam to enter your eye. Direct exposure may

adversely affect your eyesight.

Do not connect an AC power supply to the Sensor.

If AC power (100 VAC or more) is supplied to the

Sensor, it may explode or burn.

Be sure to abide by the following precautions for the safe operation of

the Sensor.

● Operating Environment

Do not use the Sensor in locations with explosive or flammable gas.

● Wiring

Power Supply Voltage and Output Load Power Supply

Voltage

Make sure that the power supply to the Sensor is within the rated

voltage range. If a voltage exceeding the rated voltage range is

supplied to the Sensor, it may explode or burn.

Power Supply Voltage

The maximum power supply voltage is 26.4 VDC. Applying a voltage

exceeding the rated range may damage the Sensor or cause burning.

Load

Do not use a load that exceeds the rated load.

Load Short-circuiting

Do not short-circuit the load, otherwise the Sensor may be damaged

or it may burn.

Connection without Load

Do not connect the power supply to the Sensor with no load

connected, otherwise the internal elements may explode or burn.

Always connect a load when wiring.

Do not use the product in atmospheres or environments that exceed

product ratings.

● Laser Warning Labels

Be sure that the correct laser warning label (enclosed) is attached for

the country of intended use of the equipment containing the

Photoelectric Sensor. Refer to the user's manual for details.

● Usage Environment

Water Resistance

The Sensor is rated IP67. Do not use it in water, in the rain, or

outdoors.

Ambient Environment

Do not install the product in the following locations. Doing so may

result in product failure or malfunction.

• Locations subject to excess dust and dirt

• Locations subject to direct sunlight

• Locations subject to corrosive gas

• Locations subject to organic solvents

• Locations subject to shock or vibration

• Locations subject to exposure to water, oil, or chemicals

• Locations subject to high humidity or condensation

● Designing

Power Reset Time

The Sensor is ready to operate 100 ms after the Sensor is turned ON.

If the load and Sensor are connected to independent power supplies

respectively, be sure to turn ON the Sensor before supplying power

to the load.

● Wiring

Avoiding Malfunctions

If using the Sensor with an inverter or servomotor, always ground the

FG (frame ground) and G (ground) terminals, otherwise the Sensor

may malfunction.

● Mounting

Mounting the Sensor

• If Sensors are mounted face-to-face, make sure that the optical

axes are not in opposition to each other. Otherwise, mutual

interference may result.

• Always install the Sensor carefully so that the aperture angle range

of the Sensor will not cause it to be directly exposed to intensive

light, such as sunlight, fluorescent light, or incandescent light.

• Do not strike the Photoelectric Sensor with a hammer or any other

tool during the installation of the Sensor, or the Sensor will lose its

water-resistive properties.

• Use M3 screws to mount the Sensor.

• When mounting the case, make sure that the tightening torque

applied to each screw does not exceed 0.54 N·m.

Metal Connectors

• Always turn OFF the power supply to the Sensor before connecting

or disconnecting the metal connector.

• Hold the connector cover to connect or disconnect it.

If the XS3F is used, always tighten the connector cover by hand. Do

not use pliers.

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 0.3 to 0.4 N·m.

If other commercially available connectors are used, follow the

recommended connector application conditions and recommended

tightening torque specifications.
