This product has been developed / produced for industrial use only.
Make sure that the power supply is off while wiring.
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.
In case noise generating equipment (switching regulator, inverter motor, etc.) is
used in the vicinity of this product, connect the frame ground (F.G.) terminal of the
equipment to an actual ground.
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.
Do not use during the initial transient time (0.5 sec.) after the power supply is
switched on.
Take care that short-circuit of the load or wrong wiring may burn or damage the
sensor.
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.
Make sure to use the optional quick-connection cable for the connection of the
amplifier. Extension up to total 100m is possible with 0.3mm

2

, or more, cable.
However, in order to reduce noise, make the wiring as short as possible.
This sensor is suitable for indoor use only.
Avoid dust, dirt, and steam.
Take care that the sensor does not come in contact with water, oil, grease, organic
solvents, such as, thinner etc., or strong acid, and alkaline.
This sensor cannot be used in an environment containing inflammable or
explosive gases.
Never disassemble or modify the sensor.

●●Never use this product as a sensing device for personnel

protection.
In case of using sensing devices for personnel protection,

use

products which meet

standards, such as OSHA

, ANSI or IEC

etc.

, for personnel protection applicable in each region or

country.

①②Fit the rear part of the mounting section of the amplifier

on a 35mm width DIN rail.
Press down the rear part of the mounting section of the
unit on the 35mm width DIN rail and fit the front part of
the mounting section to the DIN rail.

How to mount the amplifier

②

①②Push the amplifier forward.

Lift up the front part of the amplifier to remove it.

②

Take care that if the front part is lifted without pushing the
amplifier forward, the hook on the rear portion of the mounting
section is likely to break.

How to connect the fiber cables

①
②

③

Snap the fiber lock lever down.
Insert the fiber cables slowly into the inlets until they
stop. (Note 1)
Return the fiber lock lever to the original position, till it
stops.

Notes: 1)

2)

In case the fiber cables are not inserted to a position where
they stop, the sensing range reduces. In case of a flexible
fiber, take care that it may bend inside the amplifier, during
insertion.
With the coaxial reflective type fiber, such as, FD-G4 or FD-FM2, insert the single-core fiber
cable into the beam-emitting inlet and the multi-core fiber cable into the beam-receiving
inlet. If they are inserted in reverse, the sensing accuracy will deteriorate.

Make sure that the power supply is off while connecting or disconnecting the
quick-connection cable.

②

Holding the connector of the quick-connection cable, align
its projection with the groove at the top portion of the
amplifier connector.
Insert the connector till a click is felt.

① Pressing the projection

Make sure that the power supply is off while adding or removing the amplifiers.
Make sure to check the allowable ambient temperature, as it depends on the
number of amplifiers connected in cascade.
In case two, or more, amplifiers are connected in cascade, make sure to mount
them on a DIN rail.
When the amplifiers move on the DIN rail depending on the attaching condition,
fitting them between the optional end plates (MS-DIN-E) mounted at the two ends.
When connecting in cascade, mount the amplifiers close to each other, fitting them
between the optional end plates (MS-DIN-E) mounted at the two ends.
Up to maximum 15 amplifiers can be added (total 16 amplifiers connected in cascade.)
When connecting more than two amplifiers in cascade, use the sub cable (CN-71-C□)
as the quick-connection cable for the second amplifier onwards.
The settings other than the interference prevention function cannot be transmitted
between this product and other digital fiber amplifiers. Therefore, in case both
models of amplifiers are mounted in cascade, be sure to mount identical models
together.

INTERFERENCE PREVENTION FUNCTION

11

● This product incorporates an automatic interference prevention function. If the

amplifiers are mounted in cascade, since a different emission timing is automati­cally set for up to 4 amplifiers, up to 4 sets of fibers can be mounted closely.
Further, even if the amplifiers are mounted closely along with the digital fiber
sensor FX-30□, the interference prevention function works. However, in case both
models of amplifiers are mounted in cascade, mount identical models together.

MODE SELECTION SWITCH

8

●●For FX-311(P), the most suitable sensing mode can be selected according to

the application from LONG (long range distance), STD (standard) or S-D
(reduced intensity). Furthermore, for FX-311B(P) and FX-311G(P), the
sensing mode can be selected from LONG (long range distance), STD
(standard) or FAST (high speed sensing).
Make sure to carry out sensitivity adjustment after mode setting.

Mode Application

Used for general sensing application.

Since the emitted light amount is restricted in this mode,
it is suitable for delicate sensing, such as when the

When 'assist function' is not used, the pointer does not flash.
When 'assist function' is not used, the middle point of and is regarded as the optimum
sensitivity point.
In order to protect the mechanism, the sensitivity adjuster idles when over turned, which
may result in a backlash of 1 to 2 divisions.
Depending upon the sensing conditions, stable sensing may be possible at a position
which is slightly shifted from the optimum sensitivity point.
Do not move or bend the fiber cable after the sensitivity adjustment. Detection may
become unstable.

★Make sure that the

operation selection
switch is set to L-ON
(Light ON).
In case 'assist function' is to
be used, switch the operation
selection switch in the order
of

L-ON (Light ON) → D-ON

(Dark ON) → L-ON (Light ON).

Turn the sensitivity adjuster fully counterclock­wise. (Minimum sensitivity)

Thru-beam type

In the beam received condition, slowly turn the
adjuster clockwise and find the point where
the sensor is switched ON. The pointer flashes
once at the point . (Note 1)

Beam received Beam received

Beam not
received

Beam not
received

In the beam not received condition, slowly turn
the adjuster further clockwise until the sensor
goes into the ON state again. Once it is switched
on, turn the adjuster counterclockwise a little and
find the point where it is switched OFF. The
pointer flashes twice at the point . (Note 2)

If the sensor does not go into the ON state,
MAX is the point .

Optimum point

Select either L-ON (Light ON) or D-ON (Dark ON) according to your application.⑤

Turn the adjuster towards the point from the point

slowly. The pointer starts flashing when it a
proaches the optimum sensitivity point and
flashes faster at the optimum sensitivity point for 3
sec.
This point is the optimum sensitivity point.

TIMER FUNCTION

10

● This product incorporates an OFF-delay timer function. The delay time can be

selected as either 10ms. approx. or 40ms. approx. with the timer selection switch.
Since the output is extended by a fixed period, it is useful when the connected
device has a slow response time or when small objects are being sensed and the
output signal width is small.

Note: The diagram shows the case when 10ms delay time is selected.

SENSITIVITY ADJUSTMENT

●

●

●

●

Adjust the sensitivity, observing the
operation indicator (orange). However,
since the condition for lighting up of the
indicator depends on the combination of
the sensing condition and the selected
operation of L/D-ON, verify it from the
table on the right.
The sensitivity adjuster is a 12-turn
potentiometer.

The maximum sensitivity is obtained by turning it fully clockwise.

The pointer shows the present sensitivity level.

Assist function

This product incorporates an 'assist function', which helps to easily
search the optimum sensitivity position by flashing of the pointer. In order
to make 'assist function' effective, switch the operation selection switch in the order
L-ON (Light ON) → D-ON (Dark ON) → L-ON (Light ON).

In case 'assist function' is not to be used, set the operation selection switch to D-ON (Dark
