This product is not designed or rated for ensuring safety of persons.
Do not use it for such purposes.
Never look into the laser beam. Doing so continuously will result in
visual impairment.
Do not attempt to dismantle, pressurize, or incinerate the product. Doing
so may cause the laser beam to leak, resulting in the danger of visual
impairment.

Precautions for Safe Use
The following points are important to ensure safety, so make sure that they are strictly
observed.
1. Installation Environment
• Do not use the product in environments where it can be exposed to inflammable/
explosive gas.
• To secure the safety of operation and maintenance, do not install the product close to
high-voltage devices and power devices.
• Install the product in such a way that its ventilation holes are not blocked. (excluding
the connecting surface when the products are connected to each other)
• Tighten the mounting screws with a torque specified in this manual.
2. Power Supply and Wiring
• The voltage and AC power supply must be within the rated range (24 VDC +10%, -15%).
• Reverse connection of the power supply is not allowed. Connection to an AC power
supply is also not allowed.
• The output load should not be short-circuited.
• Use the power supply within the rated load.
• High-voltage lines and power lines must be wired separately from this product. Wiring
them together or placing them in the same duct may cause induction, resulting in
malfunction or damage.
• Use the product within the power supply voltage specified by this manual.
• Use a DC power supply with safety measures against high-voltage spikes (safety extra
low-voltage circuits on the secondary side).
• Use only combinations of the Sensor and Controller specified in this manual.
Controller Specifications p.133
• When connecting Controllers to each other, use only combinations of the Controllers
specified in this manual.
Connecting Controllers to each other p.37
• Connect the exclusive device (Sensor). The product might break down or malfunction
if you use a part not included in the exclusive products.
3. Other
• Do not disassemble, repair, modify, pressurize, or incinerate the product.
• Dispose of this product as industrial waste.
• Should you notice any abnormalities, immediately stop use, turn OFF the power
supply, and contact your OMRON representative.

Precautions for Correct Use
Observe the following precautions to prevent failure to operate, malfunctions, or
undesirable effects on product performance.
1. Installation Site
Do not install this product in locations subjected to the following conditions:
• Ambient temperature outside the rating
• Rapid temperature fluctuations (causing condensation)
• Relative humidity outside the range of 35 to 85%
• Direct vibration or shock
• Reflection of intense light (such as other laser beams or electric arc-welding machines)
• Direct sunlight or near heaters
• Strong magnetic or electric field
Also, do not install this product in locations subjected to the following conditions due to
the degree of protection specified in the ratings:
• Presence of corrosive or flammable gases
• Presence of dust, salt, or iron particles
• Water, oil, or chemical fumes or spray
2. Power Supply and Wiring
• When using a commercially available switching regulator, make sure that the FG
terminal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit the
operating environment.
• Before turning ON the power after the product is connected, make sure that the power
supply voltage is correct, there are no incorrect connections (e.g. load short-circuit), and
the load current is appropriate. Incorrect wiring may result in breakdown of the product.
• Before connecting/disconnecting devices, make sure that the Sensor/Controller is
turned OFF. The Sensor or Controller may break down if it is connected/disconnected
while the power is ON.
• Use the extension cable sold separately for extending the cable between the Sensor
(receiver) and the Controller.
p.20
3. Warming Up
After turning the power supply ON, allow the product to stand for at least 10 minutes
before use. The circuits are still unstable just after the power supply is turned ON, so
measurement values may fluctuate gradually.
4. Maintenance and Inspection
Do not use thinner, benzene, acetone or kerosene to clean the Sensor and Controller. If
large dust particles adhere to the filter on the front of the Sensor, use a blower brush
(used to clean camera lenses) to blow them off. Do not use breath from your mouth to
blow the dust off. To remove dust particles from the Sensor, wipe gently with a soft cloth
(for cleaning lenses) moistened with a small amount of alcohol. Do not use excessive
force to wipe off dust particles. Scratches to the filter might cause error.

Mounting the Sensor
Never look into the laser beam. Doing so continuously will result in
visual impairment.
Do not attempt to dismantle, pressurize, or incinerate the product. Doing
so may cause the laser beam to leak, resulting in the danger of visual
impairment.
Important
If a measurement target has a shiny surface, reflected light might adversely influence adjacent
Sensors. Mount the Sensor so that it is not influenced by reflected light.
Example: XY cross measurement
Place the Sensors so that their optical axes do not overlap each other.

Mounting the Controller
1
1 Hook the connector end of the
Controller onto the DIN track.
Important
Always hook the connector end of the
Controller onto the DIN track first. Mounting
strength may decrease if the I/O cable end
is hooked onto the DIN track first.

2 Push the Controller down onto
the DIN track until the hook on the
I/O cable side is locked.
Important
After mounting the Controller on the DIN
track, attach the end plates (sold
separately) on both sides of the Controller.
DIN track (sold separately)
PFP-100N (1 m)
PFP-50N (0.5 m)
PFP-100N2 (1 m)
End plate
1 Push the Controller up towards
the connector side.
2 Lift up the Controller from the
connector end, and remove it
from the DIN track.

Important
Before connecting/disconnecting the Sensor, make
sure that the Controller is turned OFF. The
Controller may break down if the Sensor is
connected or disconnected while the power is ON.
1 Insert the receiver connector into
the Controller connector.

Note
When the measurement cycle has been changed to the high-speed mode (FAST), wiring of
the sync wires is not required. Note, however, that the Controller becomes more susceptible
to the influence of ambient light in this case.
2 Connect the Controller and
Sensor sync wires.
Controller sync output wire : yellow
Emitter sync input wire : red
Important
The Controller's default mode is the
standard mode. Measurement is not
possible without the sync wires connected.
3
Connect the power wire (brown)
and the GND wire (blue) of the
emitter and the Controller I/O cable.
Note
The following power supply is
recommended:
• S8VS-03024 (24 VDC, 1.3 A)
Important
Do not mount the Controller in such a way that a load is steadily applied on the connector, for
example, with tension applied to the cables.
