CAUTIONS
2ƔThis product has been developed / produced for
industrial use only.
ƔAvoid using the product in an explosive
atmosphere because this product does not have
an explosive-proof protective construction.
ƔMake sure that the power supply is off while wiring.
ƔTake care that wrong wiring will damage the sensor.
ƔVerify that the supply voltage variation is within
the rating.
Take care that if a voltage exceeding the rated
range is applied, or if anAC power supply is directly
connected, the sensor may get burnt or damaged.
ƔIf power is supplied from a commercial switching
regulator, ensure that the frame ground (F.G.)
terminal of the power supply is connected to an
actual ground.
ƔDo not use during the initial transient time (approx.
50m sec. ) after the power supply is switched on.
ƔIn case noise generating equipment (switching
regulator, inverter motor, etc.) is used in the vicin-
ity of this product, connect the frame ground (F.G.)
terminal of the equipment to an actual ground.
ƔCable extension is possible up to total 50m with
0.3mm2, or more, cable. However, in order to re-
duce noise, make the wiring as short as possible.
ƔDo not run the wires together with high-voltage lines
or power lines or put them in the same raceway.
This can cause malfunction due to induction.
ƔIn case a surge is generated in the used power sup-
ply, connect a surge absorber to the supply and ab-
sorb the surge.
Ɣ%e sure to use the exclusive mounting bracket when installing
the sensor to avoid human error, etc. Reliable detection can-
not be guaranteed when this mounting bracket is not used.
MOUNTING

(;)Ƒ
ƔInsert the M4 stud-bolt (length 10mm or more)
welded on the user’s facilities into the mounting
hole of the SUS mounting bracket and screw with
an M4 nut (please arrange separately).
The tightening torque should be 0.98N·m or less.

How to ¿t the sensor body to the exclusive mounting bracket
<In case of using the PVC mounting bracket for adhesive ¿xing>
ƔUse adhesive to stick fast the mounting bracket
on the mounting surface. Please note that if the
adhesive sticks out from the bottom surface of
the mounting bracket or is 0.5mm, or more thick,
the sensor body cannot be ¿tted to the mounting
bracket.
ƔMatch the notch in the sensor body with the
projection of the exclusive mounting bracket and
slide till a click is felt.

INTENDED PRODUCTS FOR CE MARKING
5ƔThe models listed under “ SPECIFICA-
TIONS” come with CE Marking.
As for all other models, please contact our
of¿ce.
ƔTake care not to use the SUS mounting bracket for
EX-F72Ƒor the PVC mounting bracket for EX-F71Ƒ
mistakenly, since normal detection cannot be performed.
ƔMake sure to use an isolation transformer for the
DC power supply. If an auto-transformer (single
winding transformer) is used, this product or the
power supply may get damaged.
ƔIn case air bubbles are drawn into the sensing part,
take care that it may take some time for sensing to
stabilize, or sensing may even become unstable.
ƔWhen conducting maintenance after operation,
wipe all liquid from the sensor and mounting
bracket with a soft cloth.
ƔIf there is liquid remained or scratch on the sensing
surface or the exclusive mounting bracket, normal
operation cannot be performed.
ƔSince this sensor employs non-modulated infrared
LED, take suf¿cient care against extraneous light.
Do not expose the sensing part directly to the
extraneous light.
ƔAvoid dust, dirt, and steam. Further, do not use this
product in an environment containing organic solvents.
ƔTake care that the product does not come in
contact with oil, grease or organic solvents, such
as, thinner, etc.
ƔIn case this sensor is used where electrostatic
charge is present, use a metal leak pan, which
should be connected to an actual ground.
Thank you very much for purchasing Panasonic products.
Please read this Instruction Manual carefully and thor-
oughly for the correct and optimum use of this product.
Kindly keep this manual in a convenient place for quick reference.
ƔNever use this product as a sensing device for
personnel protection.
ƔI
n case of using sensing devices for personnel protec-
tion, use products which meet laws and standards, such
as OSHA, ANSI or IEC etc., for personnel protection ap-
plicable in each region or country.
