Snap the fiber lock lever down.
Insert fiber cables slowly into the
inlets until they stop. (Note 1)
Lock the fiber lock lever in the
original position, till you feel a
click.
With the coaxial reflective type fiber, such as, FD-G4, FD-FM2, insert the
center fiber cable (single-core) into the beam-emitting inlet and the outer fiber
cable (multi-core) into the beam-receiving inlet. If they are inserted in reverse,
the sensing accuracy will deteriorate.
Notes: 1)
2)
In case the fiber cables are not inserted to a position where they stop, the
sensing range reduces.
Make sure to carry out the wiring in the power supply off condition.
Verify that the supply voltage variation is within the rating.
Avoid dust, dirt, and steam.
Extension up to total 100m is possible with a 0.3mm2, or more, cable.
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.
The self-diagnosis output is not incorporated with a short-circuit
protection circuit. Do not connect it directly to a power supply or a
capacitive load.
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.
Do not use during the initial transient time (0.5 sec.) after the power
supply is switched on.
Take care that the product does not come in direct contact with
water, oil, grease or organic solvents, such as, thinner, etc.

(Common for all models)
Part description
Refer to the catalog as the sensing range differs according to the type of fiber
cable. The sensing range of the reflective type fiber cable is the value for
white non-glossy paper. The actual sensing distance differs according to the
color of the sensing object, its surface condition, etc.
The sensitivity can also be set under unstable sensing condition. But the
severe condition may affect the sensing.
The set sensitivity is stored in an EEPROM. Since the EEPROM has a
lifetime, the sensitivity setting cannot be done for more than 100,000 times.
Do not move or bend the fiber cable after the sensitivity setting. Detection
may become unstable.

body for identification. Please use this, when required.
Off-delay timer function
(For standard and remote sensitivity setting types only)
Standard and remote sensitivity setting types have an approx. 40ms
fixed off-delay timer. The timer works when the timer operation
selection switch is set to ‘OFD’. The output is extended for a certain
period of time, and is useful when the response time of the connecting device is slow or when the sensing signal from a tiny object is
too short.
Time chart
Use of remote sensitivity setting input
(For FX-77, FX-77G only)
Basically, the method is similar to that described in ‘Use of sensitivity
setting buttons’. However, instead of pressing the sensitivity setting
buttons, make the remote sensitivity setting inputs Low.
Answer back function
The self-diagnosis output turns ON for approx. 40ms when ON input or OFF
input is accepted by the sensor. (This output does not turn ON if there is no
sensitivity difference between ON input and OFF input and stable sensing is
not achieved.)
Cancelling the setting made by remote sensitivity setting inputs
Time chart
Sensitivity margin indicating function (Incorporated in all models)
After setting the sensitivity, the margin of the sensitivity can be
visually confirmed. The sensitivity margin can be confirmed by the
number of times the stability indicator (green) blinks when the
mode selection switch is changed from ‘SET’ to ‘SIF’ or ‘RUN’.
Normally, the margin should be set as large as possible. (Method of
increasing the margin: shorten the sensing distance, use the
optimum fiber cable, etc.)
Interference prevention function (Incorporated in all models)
The FX-7 series has a built-in interference prevention function. Two fiber cables
can be mounted very closely by setting different emission frequencies.

Sensitivity registered by remote sensitivity setting inputs has a priority over
the manual setting and it cannot be cancelled manually. To cancel the
remote sensitivity setting, arrange one switch at the position
shown in the figure, and
make it open. (The
sensitivity will be locked.)
Turn on the switch for
making sensitivity settings
effective.
Note: When using the interference prevention function, the hysteresis and
the response time increase as compared to that during normal operation. Always check the operation after setting the interference prevention function.

Sensing of a tiny object with the thru-beam type
1. Set the mode selection switch to ‘SET’.
2. Press ‘OFF’ button (or ON button) without the sensing
object.
3. Press ‘ON’ button (or OFF button) when light is
completely interrupted.
4. Set the mode selection switch to ‘SIF’.
5. Press the button again which was pressed without the
sensing object.
6. Set the mode selection switch to ‘RUN’.
External synchronization function (For FX-75, FX-75G only)
By using external synchronization function, the timing for making
detection can be specified.
Trigger synchronization and gate synchronization are available.
Time chart
Emission disable function (For FX-75, FX-75G only)
Emission stops when emission disable input (violet) is set Low. The
sensing output can be turned ON and OFF without a sensing object
and this can be used for start-up inspections.
It is judged that sensor operation is normal if sensing output follows
the ON and OFF of the emission disable input, and is abnormal if it
does not follow.
Self-diagnosis function (Incorporated in all models)
The self-diagnosis output transistor is ‘OFF’ during stable sensing.
If the sensor does not reach at either stable light receiving level or
stable light interruption level when sensing output turns ON or OFF,
the self-diagnosis output turns ON and then turns OFF after approx.
40ms. Further, the self-diagnosis output changes at the time when
the sensing output changes from light received to light interrupted
state. (The operation of the sensing output is not affected.)
There is a time delay in turning ON of the self-diagnosis output
when light interruption is insufficient.
Reflective type
