●

FX-311 realizes the ultimate in ease-of-operation.
Its operation enables easy and full use of latest technology.

Presenting a product which satisfies professionals using volume control. Besides featuring an operation which makes
full use of the latest functions easy, it provides maximum flexibility in dealing with different situations. FX-311 is, indeed,
a professional fiber sensor.

Simple Realization of Ultimate in Easy-of-operation

Operation indicator

Stability indicator

Operation selection switch

Selectable either
L-ON (Light-ON) or
D-ON (Dark-ON)

12-turn Potentiometer with Visible Indicator

12-turn potentiometer has been incorporated for fine adjustments.
It enables detection of very fine differences.
Moreover, since the pointer of indicator has a red backlight, its
position can be confirmed at a glance even in a dark area.

Selectable Timer Period of OFF-delay Timer

FX-311 incorporates an OFF-delay timer. 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. The timer
period can be selected not only 40ms but also 10ms. It is also
suitable for increased PLC speeds.

Selectable Between Three Modes According to Application

The most suitable sensing mode can be selected according to the
application from three different modes with the mode selection
switch.

Selectable between three modes

Applications

• When using long-range mode
Sensing the presence

of a translucent sheet

•

When using reduced intensity mode

Detecting PCB rack

Long-range mode
(LONG)

Used in case long distance sensing is required.
(Response time: 2ms)

Used for general sensing application.
(Response time: 250!s)

Standard mode
(STD)

Reduced
intensity
mode
(S-D)

Since the emitted light amount is restricted in this mode, it is
suitable for delicate sensing, such as when the received light
is saturated due to too short a sensing distance or when
detecting translucent objects, etc. (Response time: 250!s)

Easy Adjustment with ‘Assist Function’ for Knowing
Optimum Sensitivity

FX-311 has a built-in convenient ‘assist function’ which indicates the optimum

sensitivity position by the rapid flashing of the indicator at the time of sensitivity
adjustment. This enables easy and reliable sensitivity adjustment, which is
convenient for a narrow sensing range requiring fine tuning.

Easy Operation by Using a Convenient, Hand-turned
Adjusting Knob of Hand-turned Knob Attached Cover

An optional hand-turned knob attached cover (FX-AJ1/AJ1P) is
available, which makes a screwdriver unnecessary. On-site
adjustment of sensitivity can be done at any time quickly and easily.

Now It’s Possible to Simultaneously Cut Two
Fibers to the Same Length

Each fiber (with some exceptions) has a newly developed two-in-one
fiber attachment

(FX-AT2/AT3/AT4/AT5/AT6)

which enables two
fibers to be cut simultaneously to the same length with the new fiber
cutter (FX-CT2).

Also, since the fibers can be attached to the
amplifier while being fixed in position in the two-in-one fiber
attachment, sensitivity changes due to variation in the amount of
fiber insertion do not occur.

Innovative product based on FX-301 design concepts.
Advanced manual setting fiber sensor.

Utilizes the Most Advanced Optical
Technology Offered by SUNX

The original SUNX optical technology developed for the FX-301 digital fiber
sensor, including its benefits of simple maintenance, reduced wiring and
easy installation, is taken a step further with FX-311.
FX-311 incorporates technology to handle every major concern and deliver
superior performance for a variety of on-site requirements.

Long Life and Stable
Operational Settings
Assure Dependable Performance

Newly

developed

The light-emitting elements of conventional
fiber sensors are affected by temperature
and long-term use, changing their emission
over time and requiring sensitivity
readjustment. FX-311 uses the newly
developed ‘LED using four chemical
elements’, a new LED first used in FX-301.
This emitter greatly reduces adverse
influences on emission performance,
resulting in stable operation that almost
never needs adjustment.

The new developed optical ‘double coupling
lens’ has been incorporated directly into the
fiber sensor itself. This lens maximizes the
light emission efficiency, resulting in a
tremendous improvement in the sensing
range. Sensing ranges with small diameter
fiber and ultra-small diameter fiber, which
have become very popular in recent years
due to the miniaturization of chip
components, have been increased by 50%
over previous values achieved with other
amplifiers.

Specially Designed for Flexible Use
and Simple Operation

Maintenance Made Easy with Quick-connection Cables

Both main and sub units utilize the same amplifier body. This
feature allows for easy mounting in the side-by-side configuration,
because main and sub unit functions are distinguished only by the
proper use of 3-core main cable for the main unit and 1-core sub
cable for each sub unit. Moreover, due to the utilization of the same
main body for both main and sub units, inventory management and
maintenance, is simplified.

Each sub cable is a single output wire, reducing wiring and
simplifying installation. Quick-connection cables are the same type
as used on the FX-301, facilitating side-by-side connection. Further,
the connectors are slide type, allowing removal without shifting
amplifier positions. This eliminates the need to provide extra
maintenance space around the amplifiers.

Close Mounting Is Possible for up to
Four Fiber Heads

If amplifiers are mounted side-by-side in cascade, the optical
communication function automatically sets different emission timing
for the amplifiers, at the time of switching on the power supply. Up to
four fiber heads can be mounted closely, without mutual interference.
FX-301 units can also be used in these configurations.

Part description

Mode selection switch

The most suitable sensing mode can be selected according to the
application from LONG(long-range), STD (standard) or S-D (reduced
intensity).

Application

Note: Make sure to carry out sensitivity adjustment after mode setting.

Since the emitted light amount is restricted
in this mode, it is suitable for delicate
sensing, such as when the received light is
saturated due to too short a sensing
distance or when detecting translucent
objects, etc.

Used for general sensing application.

13

Used in case long distance sensing is
required.

However, the response time is longer
than in STD mode.

operation

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)

n D-ON (Dark-

n L-ON(Light-ON).



A

Notes: 1) When ‘assist function’ is not used, the pointer does not flash.

2) When ‘assist function’ is not used, the middle point of A and B is
regarded as the optimum sensitivity point.

3)

In order to protect the mechanism, the sensitivity adjuster idles when

over turned, which may result in a backlash of 1 to 2 divisions.

4)

Depending upon the sensing conditions, stable sensing may be possible

at a position which is slightly shifted from the optimum sensitivity point.

5) Do not move or bend the fiber cable after the sensitivity adjustment.

Detection may become unstable.

Wiring

Sensitivity adjustment

Others

• Make sure to carry out the wiring in the power supply off condition.

• 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.

• 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
motor, etc.) is used in the vicinity of this product, connect the
frame ground (F.G.) terminal of the equipment to an actual ground.

• Take care that short-circuit or wrong wiring of the load 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.

• Ensure that an isolation transformer is utilized for the DC power
supply. If an autotransformer is utilized, the main amplifier or
power supply may be damaged.

• Make sure to use the optional quick-connection cable for the
connection of the amplifier. 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.

• Do not use during the initial transient time (0.5 sec. approx.) after
the power supply is switched on.

• Take care that the sensor is not directly exposed to fluorescent
light from a rapid-starter lamp or a high frequency lighting device,
as it may affect the sensing performance.

• This sensor is suitable for indoor use only.

• Avoid dust, dirt, and steam.

• Take care that the product does not come in direct contact with

organic solvents, such as, thinner, etc.

• This sensor cannot be used in an environment containing
inflammable or explosive gases.

• Never disassemble or modify the sensor.

•

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 fiber heads can be mounted closely.
Further, even if the amplifiers are mounted closely along with
digital fiber sensor FX-301(P), the interference prevention
function works. However, in case both models of amplifiers are
mounted in cascade, mount identical models together.

Interference prevention function

PRECAUTIONS FOR PROPER USE

Refer to Sensor General Catalog for fiber’s precautions.

•

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 selected operation for 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.

Notes: 1)

‘Assist function’ cannot be used when adjusting sensitivity for moving objects.

2)

‘Assist function’ turns off automatically once the sensitivity adjustment has been completed.

3)

In case ‘assist function’ is not to be used, set the operation selection switch to
D-ON(Dark-ON) and wait for 2 sec., or more, to make ‘assist function’ ineffective.

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) n D-ON (Dark-ON) n
L-ON (Light-ON).

Turn the sensitivity adjuster
fully counterclockwise.
(Minimum sensitivity)

In the beam received
condition, slowly turn the
adjuster clockwise and find
the point

A where the
sensor is switched ON. The
pointer flashes once at the
point A. (Note 1)

Turn the adjuster towards
the point A from the point
B slowly. The pointer starts
flashing when it ap­proaches the optimum
sensitivity point and flashes
faster at the optimum
sensitivity point for 3 sec.
This point is the optimum
sensitivity point. (Note 2)

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 B
where it is switched OFF.
The pointer flashes twice
at the point B . (Note 2)

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

This product incorporates OFF-delay timer function. The timer period
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.
