Safety Precautions
Refer to Warranty and Limitations of Liability on page 20.
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 op-
eration of the Sensor.
Operating Environment
Do not use the Sensor in locations with explosive or flamma-
ble 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.
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 indepen-
dent power supplies respectively, be sure to turn ON the Sen-
sor 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, oth-
erwise the Sensor may malfunction.
Mounting
Mounting the Sensor
• If Sensors are mounted face-to-face, make sure that the op-
tical axes are not in opposition to each other. Otherwise,
mutual interference may result.
• Always install the Sensor carefully so that the aperture an-
gle range of the Sensor will not cause it to be directly ex-
posed 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.
