FS-N10 Series
Instruction Manual
Hints on Correct Use
• Do not wire the amplifier line along with power lines or high-tension lines, otherwise the sen-
sor may malfunction or receive damage due to noise.
• When using a commercially available switching regulator, ground the frame ground terminal
and ground terminal.
• Do not use the FS series outdoors, or in a place where extraneous light can enter the light-
receiving surface directly.
• Due to the individual dispersion of characteristics and the difference in fiber unit model, the
maximum sensing distance or displayed value of all the units are not the same.
• If the sensor is used in S-APC mode for a long time, the LED indicators will be imposed with
a heavy load. In that case, the sensor will be automatically set to ACC mode where the current consumption of the sensor for light emission will be constant, and “END APC” will be
displayed. The sensor can be continuously used in this case. Replace the sensor, however, if
highly precise detection is required.

FS-N10 Series Quick Start and Cabling
Quick Start
*1 This is a channel switch on 2-output types.
*2 Press and hold the [MODE] button to make advanced settings.
Cabling
Mounting Unit
Mounting on a DIN Rail
1 Align the claw at the bottom of the main body with
the DIN rail, as shown in figure1.
While pushing the main body in the direction of
the arrow 1, slant it in the direction of the arrow 2.
2 To dismount the sensor, raise the main body in
the direction of the arrow 3 while pushing the
main body in the direction of the arrow 1.
Installation on a Wall (Main Unit Only)
1 Attach the unit to the optional mounting bracket (OP-
73880), mount them together, and secure them with
two M3 screws as shown in figure2.
Connecting Fiber Unit
1 Open the dust cover in the direction shown by
arrow 1.
2 Move down the fiber lock lever in the direction
shown by a rrow 2.
3 Insert a fiber unit into the fiber insertion holes
to a length of the fiber insertion sign (i.e.,
approximately 14 mm).
4 Move down the fiber lock lever in the direction
shown by a rrow 4.

•
This product is used to detect targets. Do not apply the
product to safety circuits for human protection.
• This product is not of explosion-proof construction. Do not
use the products in places with flammable gas, liquid, or
dust.
• This product is a sensor of DC power supply type. Do not
apply AC power. The product may explode or burn if an AC
voltage is applied.

Warning
See page 4 for information about connecting to external devices other than the FSN11N.
• If a thin fiber unit is used, an adapter provided with the thin fiber unit will be
required.
Unless the correct adapter is connected, the thin fiber unit will not detect
targets correctly (the adapter is supplied with the fiber unit).
• To connect the coaxial reflective type fiber unit to the amplifier, connect the
single-core fiber to the transmitter side, and connect the multiple-core fiber
to the receiver side.

Connecting Multiple Amplifiers
Up to 16 sub units can be connected to one main unit.
1 Remove the protection covers of the main unit and
sub unit(s).
2 Install the amplifiers one by one on the DIN rail.
3 Engage the two claws of the sub unit with the
recesses on the main unit side until you hear a
click.
4 Attach the end units (option: OP-26751) to the
both ends of the connected amplifiers in the same
way as in step (2).
5 Sandwich the amplifiers between the end units.
Tighten the screws at the top (two screws x two
units) with a Phillips screwdriver to fix the end
units.
Calibration Method
Detecting Even Small Differences
z
Two-point Calibration
Two-point calibration is the basic method for making calibration.
You can set the sensitivity level automatically, simply by pressing the [SET] button twice.
Just press once with the workpiece set up, and once without.
Two-point calibration performs detection at a location where there is a workpiece, and
another location where there is not, uses the intermediate value as the setting.
If the sensitivity difference does not have enough room, "- - - -" flashes for about two seconds after the calibration is complete. The set value is stored in memory even in that case.
Other Calibration Methods
Increase Resistance to Dust and Dirt
z
Maximum Sensitivity Setting
In the state shown below, press and hold the [SET] button for three seconds and stop pushing when "5'6" flashes.
The sensitivity is set slightly higher than the light intensity.
Calibrate with Moving Workpiece
z
Full Auto Calibration
Press and hold the [SET] button with no workpiece in place, whil e “5'6” is flashing, pass
through a workpiece. (Continue pressing the [SET] button while the workpiece passes
through.)
Position Workpiece
z
Positioning Calibration
Press the [SET] button with no workpiece set.
Place the workpiece in the location you wish to position it, and press and hold the [SET] button for at least 3 seconds. Release the button when "5'6" flashes.
Mount on DIN rail and install on metal sheeting when connecting to
multiple amplifiers or mounting main units together.
• Multiple connections cannot be made to equipment other than the FS-N10
series.
• Turn the power off before connecting multiple sub units.
• Do not touch the expansion connector with your bare hands.
