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.

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.

In order to make ‘assist function’ effective, switch the operation selection switch in the order .

Find the point A where the sensor is switched ON in the sensing condition.

Optimum sensitivity point located.

Sensing (beam received) condition

Non-sensing (beam not received) condition

The pointer flashes once at the point A.

The pointer flashes twice at the point B.

Confirm the operation indicator lights up.

Detectable range

The pointer flashes faster at the optimum sensitivity.

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.

No performance deterioration over time No reduced life expectancy for elements

The light emission efficiency is increased tremendously, as light is now collected and focused into the fiber by the lens.

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.

mNOTE

Note that settings other than that of the interference prevention function cannot be transmitted between this product and digital fiber sensor FX-301(P).

Therefore, in case both models of amplifiers are mounted in cascade, make sure to mount identical models together.

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.
