This product has been developed / produced for 
industrial use only.

atmosphere because this product does not have 
an explosive-proof protective construction.

 

Ɣ

Make sure that the power supply is off while wiring.

 

Ɣ

Take care that wrong wiring will damage the sensor.

 

Ɣ

Verify that the supply voltage variation is within 
the rating.
Take care that if a voltage exceeding the rated 
range is applied, or if an AC power supply is directly 
connected, the sensor may get burnt or damaged.

 

Ɣ

If 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.

 

Ɣ

Do not use during the initial transient time (approx. 
50m sec. ) after the power supply is switched on.

 

Ɣ

In 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.

 

Ɣ

Cable extension is possible up to total 50m with 
0.3mm

2

, or more, cable. However, in order to re-

duce noise, make the wiring as short as possible.

 

Ɣ

Do 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.

 

Ɣ

In 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.

Ɣ

Insert 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.

¿

 xing>

Ɣ

Use 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.

Ɣ

Match the notch in the sensor body with the
projection of the exclusive mounting bracket and 
slide till a click is felt.

Ɣ

Take care not to use the SUS mounting bracket for
EX-F72

Ƒ

or the PVC mounting bracket for EX-F71

Ƒ

mistakenly, since normal detection cannot be performed.

Ɣ

Make 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.

Ɣ

In 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.

Ɣ

When conducting maintenance after operation,
wipe all liquid from the sensor and mounting
bracket with a soft cloth.

Ɣ

If there is liquid remained or scratch on the sensing 
surface or the exclusive mounting bracket, normal 
operation cannot be performed.

Ɣ

Since 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.

Ɣ

Avoid dust, dirt, and steam. Further, do not use this
product in an environment containing organic solvents.

Ɣ

Take care that the product does not come in
contact with oil, grease or organic solvents, such
as, thinner, etc.

Ɣ

In 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.

 

Ɣ

Never use this product as a sensing device for 
personnel protection.

 

Ɣ

In 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.
