MUTUAL INTERFERENCE SUPPRESSION FUNCTION

When several expansion units are connected, each fiber unit is free
from light interference from the adjacent fiber units.

The number of fiber units that are free from light interference depends
on the selected power mode.

Power mode FINE TURBO SUPER
No. of units free from interference 48

Note: When units are not connected using the expansion connectors,

the mutual interference suppression function does not work.
The mutual interference suppression function is limited to 4 units even
if only one unit is set to FINE mode.

■ Detaching units from DIN rail

1. Remove the end units.

2. Slide the expansion units apart, and detach them individually.
(Do not detach multiple units connected together with end units.)

The sticker shown on the right is
included in the expansion unit. Apply
this sticker near the sensor.

Note 1: When several units are connected, confirm the ambient temperature.
(See "Specifications" on P. 1.)

Note 2: To connect several units, be sure to use a DIN rail and end units.
Note 3: To mount or detach several units, be sure to turn the power off.
Note 4: Do not remove the protective cover of the expansion connector on the

outmost unit.

Lower the quick-release lever, insert the fiber unit about 14 mm until it
reaches the end, and then lift the quick-release lever.

Fiber insertion
mark

• To connect a fiber unit with a small diameter, use the adaptor
included with the FU series.

1. Attach the adaptor to the fiber
unit.

2. Fully insert the adaptor into the
mounting holes of the amplifier,
and then lift the quick-release
lever.

Note: If the fiber unit is improperly connected, the sensor cannot meet
the specifications.

• The required adaptor is included in each model of the FU series. If
an inadequate adaptor is used, the fiber unit cannot be properly
installed.

• 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.
(Connect the fibers according to the marking on the amplifier lateral
side.)

HINTS ON CORRECT USE

• To extend the cable length, use a cable with at
least a 0.3 mm2 cross-section area. Limit the
length of cable extension to no more than 100
m. (To connect several units, contact Keyence
for further information.)

• If the amplifier cable is placed together with
power lines or high voltage lines in the same
conduit, detection error may occur due to
noise interference, or the sensor may be
damaged. Isolate the amplifier cable from
these lines.

• 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.

• Improper wiring may cause the amplifier to
become hot or may change the sensitivity.

• The displayed value may vary depending on
the surrounding environment (change in
temperature, dust, etc.).

When several units are connected:

Note: Be sure to use the end units to connect to the expansion units.
