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 cur-
rent 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.

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 arrow 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 arrow 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 FS-
N11N.
• 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.
