Precautions
Safety Precaution
Laser beam!
Laser protection class 2
Do not look into the laser beam.
Pay attention to the accident prevention regulations and the
laser protection class.
Visible laser emission!
Avoid any indirect or direct radiation of
reflected or emitted laser light!
Laser safety
The laser safeguards have been stipulated for laser equip-
ment in and outside Japan. The following gives brief descrip-
tion for use in Japan.
The JIS C6802 Standard stipulates safety preventives that
must be taken by the user according to the laser product
class. (The outline is given in the following table.)
User's Requirements
* 5 mW or less in the visible range
Classification of F3C
Handle laser equipment in accordance with the following pre-
cautions.
• Do not look into the beam.
• Do not disassemble the product. Doing so will release the
laser beam to wander around.
Please obtain or prepare the "Laser product safety standards"
on your own responsibility.
Labels related to laser
The following warning label is applied to the side face of the
photoelectric sensor.
For use in Japan, change the above label for the one that
meets the JIS Standards.
Handling Instructions
F3C radiates a visible-light laser. Do not look into it directly.
Use F3C so that the light path of the laser beam is terminated.
If there is a mirror-smooth reflector in the light path, confine
the beam away from the reflected light path. If F3C must be
used with the light path open, avoid placing the light path on
the eye level.
Design
Power Reset Time
The Photoelectric Sensor is ready to sense an object in 300
ms after power-on. Therefore, use it 300 ms after power-on. If
the load and Sensor are connected to different power sup-
plies, always switch on power for the Sensor first.
Wiring Considerations
Load short-circuit protection
• The F3C-AL has load short-circuit protection. If a load short-
circuit or like has occurred, the output turns OFF. Therefore,
recheck the wiring and switch power on again. This resets
the short-circuit protection circuit. Load short-circuit protec-
tion is activated when a current of 1.8 times or more of the
rated load current flows. When using an L load, use the one
the inrush current of which is less than 1.8 times of the rated
load current.
• Do not use the input power exceeding the rated voltage.
Doing so can cause damage.
• Do not shorten the load with the open collector output. Oth-
erwise, damage might be caused.
• Run the wiring of F3C separately from the high voltage and
power cables.

Using remote
interlock
Not required
Connect the re-
mote interlock of
the laser beam to
the emergency
main interlock, the
interlock of the
room, or the inter-
lock of the door.
Key control
Not required
Do not keep the
key in the lock
when the laser
beam is not used.
Beam breaker
or attenuator
Not required
Used to protect
people from acci-
dental radiation by
the laser beam.
Warning sign
Not required
Post a proper warning sign on
the door to the room where
laser beam equipment is in-
stalled.
Beam path
Not re-
quired
The laser beam must be terminated and, as a rule,
must be enclosed. If the laser beam is exposed,
the vertical height of the beam must not be the
same as that of the eyes.
Mirror
reflection
Not required
Appropriate optical elements
must be securely attached
and you must be able to con-
trol the optical elements dur-
ing laser radiation.
Eye protect
Not required
Use eye protectors
except in special,
specified locations.
Protection
clothes
Not required
Wear protection clothes if exposure of
the skin to the laser beam may exceed
the MPE of the skin.
Training
Not required
The laser system must be operated by
only properly trained people.
Class 2
Correct Use
LASER LIGHT
DO NOT LOOK DIRECTLY INTO THE BEAM!
NOT EVEN THROUGH OPTICAL
INSTRUMENTS.
