How to mount
1. Fit the rear part of the mounting section of the
amplier on a 35mm width DIN rail.
2. Press down the rear part of the mounting sec-
tion of the unit on the 35mm width DIN rail and
t the front part of the mounting section to the
DIN rail.
Note: Take care that if the front part is lifted without pushing the amplier forward, the hook
on the rear portion of the mounting section is likely to break.
How to remove
1. Push the amplier forward.
2.
Lift up the front part of the amplier to remove it.

Thank you very much for purchasing Panasonic products. Please read this
Instruction Manual carefully and thoroughly for the correct and optimum
use of this product.
Kindly keep this manual in a convenient place for quick reference.
WARNING
● Never use this product as a sensing device for personnel protection.
●In case of using devices for personnel protection, use products which
meet laws and standards, such as OSHA, ANSI or IEC etc., for person-
nel protection applicable in each region or country.
●In case of control or adjustment using procedures other than those
specied in this instruction manual, hazardous laser radiation exposure
can result.

For mounting and removing the amplier, refer to “ MOUNTING.”
●Make sure that the power supply is OFF while adding or removing the amplier.
●Make sure to check the allowable ambient temperature, as it depends
on the number of ampliers connected in cascade.
●In case 2 or more ampliers are connected in cascade, make sure to
mount them on a DIN rail.
● When the ampliers move on the DIN rail depending on the attaching con-
dition or the ampliers are mounted close to each other in cascade, t them
between the end plates MS-DIN-E (optional) mounted at the two ends.
●Up to maximum 15 amplifiers can be added (total 16 amplifiers con-
nected in cascade).
●When connecting 2 or more ampliers in cascade, use the sub cable
CN-72-C□ (optional) as the quick-connection cable for the second am-
plier onwards.
●When connecting ampliers not close to each other in parallel, be sure to
mount the end plate MS-DIN-E (optional) at both sides of each amplier.
●When this product and other products (e.g. ber sensor
ampliers, pressure sensor controllers, etc.) are con-
nected together in cascade, install those products so
that they are in order of Group A, B, and C as shown in
the right gure. This product is included in Group C.
●As for the products that are located between di󰀨er-
ent groups, put the amplier protection seal FX-MB1
(optional) on the communication window of each
corresponding product.
●Within each group, identical models should be
connected in a lump.
● When this product and other products (ber sensor ampliers, pressure
sensor controllers, etc.) are connected together in cascade, items that
can be copied at Copy setting are limited.
Copiable items are digital display setting in RUN mode, Eco setting,
time period hold setting and CUSTOM setting.

● Be sure to set the output 1 or the output 2 before setting each item.
● The items that can be set in the output 1 and the output 2 respectively
are only 1. Threshold value, 2. Output operation, 3. Timer and 4. Output
mode. The items other than those are common.
However, in case of code setting, a combination of the output 1 / 2
can be set only for output operation, timer and output mode.
●The changed contents are not stored if turning the power OFF while
setting. Therefore, make sure to conrm the settings by pressing the jog
switch before turning the power OFF.
● When turning ON the power, normal condition is displayed [MODE indi-
cator: RUN (green) lights up] and the digital display shows the threshold
value (green) (Note) and the incident light intensity (red).

teresis mode, the threshold value can be set by either 1 / 2 / 3-point
teaching.
• For the setting, refer to “ TEACHING MODE.”
• Sets output operation either Light-ON or Dark-ON.

has to be made in PRO mode beforehand.
In case of 1-point teaching, a shift value (the initial value is 100 or 15%)
has to be set as well.
For setting, refer to <PRO 6> in “ PRO MODE.”
● When MODE indicator: TEACH (yellow) lights up, teaching can be done.

Setting of
threshold track-
ing cycle (Note)
This mode can change the threshold value depending
on the cycle (1 to 9,999 sec.) that is set with the varia-
tions of the incident light intensity. The tracking shift
amount is the one which is set at the <Shift setting>.
Output
setting
Selects whether tracking threshold when the output is
OFF or when the output is ON.
Storage
cycle setting
Selects a threshold storage cycle in EEPROM from 1 to
250 sec.
Start setting
Selects whether start tracking threshold at the time the
output turns OFF or at the time the output turns ON
after power is ON .
Note: Conducts the limit teaching for the changed incident light intensity.
Shift direction of the threshold di󰀨ers depending on the combination of the output status
and the output operation. 

Item Default
setting Description
Response time
setting Sets response time.
Timer setting
Sets operation and period of the timer.
This setting works in conjunction with the timer mode.
For the timer mode, refer to “ TIMER MODE.”
Hysteresis setting
Hysteresis can be set when the normal mode or the
window comparator mode is selected.
Shift setting Shifts the threshold value by a certain percentage in-
crement in limit teaching.
Light-receiving
sensitivity setting
Selects light-receiving sensitivity from 3 levels [4 levels,
only for ultra long distance (U-LG)].
Emission halt
setting
Selects laser emission from the sensor head to execute
or halt.
Digital display
setting
When setting to “ ” (lock OFF) and pressing
the jog switch in RUN mode, incident light intensity, in-
cident light intensity in percentage or the peak / bottom
value can be displayed on the digital display (red).
Eco setting
Power consumption can be lowered.
“ ”: Eco OFF
“ ”:
If any key operation is not carried out for 20 sec.
in RUN mode, the digital display turns OFF.
“ ”： If the key lock function is set to ON in RUN
mode, the digital display turns OFF.
Time period
hold setting
“ ”： Peak / bottom value in the digital display re-
freshing condition can be displayed.
“ ”： Peak / bottom value in the hold condition can
be displayed.
Notes 1) Display for laser amount can show the digit of max. 4,000 if “ ” for ultra high
speed or “ ” for high speed is selected in the response time setting “ ”,
but will display the digit of max. 9,999 if “ ” for standard or “ ” for ultra long
distance is selected.
2) Level 4 of the light-receiving sensitivity can be set only when “ ” for ultra long
distance (response time: 4ms or less) is set at the response time setting “ ”.
3) In order to clear the value, set the time period holding function to OFF once. Turn-
ing the power OFF can also clear the value.

● This product has been developed / produced for industrial use only.
● Make sure that the power supply is OFF while adding or removing the ampliers.
● Take care that if a voltage exceeding the rated range is applied, or if an AC
power supply is directly connected, the product may get burnt or damaged.
● Take care that short circuit of the load or wrong wiring may burn or damage the product.
●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.
● The specication may not be satised in a strong magnetic eld.
● Verify that the supply voltage variation is within the rating.
● 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.
●In case noise generating equipment (switching regulator, inverter mo-
tor, etc.) is used in the vicinity of this product, connect the frame ground
(F.G.) terminal of the equipment to an actual ground.
●The ultra long distance (U-LG) mode is more likely to be affected by
extraneous noise since the sensitivity of that is higher than the other
modes. Make sure to check the environment before use.
● Do not use during the initial transient time (0.5 sec.) after the power supply is switched ON.
● Make sure to use the quick-connection cable (optional) for the connection of the controller.
Extension up to total 100m is possible with 0.3mm2 or more, cable.
However, in order to reduce noise, make the wiring as short as possible.
● Make sure that stress by forcible bend or pulling is not applied to the sensor cable joint.
● This product is suitable for indoor use only.
● Avoid dust, dirt, and steam.
●Take care that the product does not come in contact with oil, grease,
organic solvents such as thinner, etc., strong acid or alkaline.
● This product cannot be used in an environment containing inammable
or explosive gasses.
● Never disassemble or modify the product.
● This product adopts EEPROM. Settings cannot be done 100 thousand
times or more, because of the EEPROM’s lifetime.
