In case the threshold value is to be increased
(sensitivity to be reduced), turn the jog
switch to the ‘
ם
’ side to increase the
threshold value slowly.
If the jog switch is turned continuously
to the ‘
ם
’ side, the threshold value
increases rapidly.
In case the threshold value is to be
decreased (sensitivity to be
increased), turn the jog switch to the
‘
מ
’ side to decrease the threshold
value slowly. If the jog switch is turned continuously to
the ‘
מ
’ side, the threshold value decreases rapidly.

• The setting for whether the timer is used or not can be
done when MODE indicator / TIMER (yellow) lights up.
• 10 ms OFF-delay (initial value) timer is automatically set
when the timer is set to be used.
• Further, an OFF-delay (initial value) which is useful when
the response of the connected device is slow, etc., an ON-
delay which is useful to detect only objects taking a long
time to travel, and ONE SHOT, which is useful when the
input specifications of the connected device require a
signal of a fixed width, are possible with the FX-301
series. Refer to the ‘Fiber Sensor Guide Book’ or ‘SUNX
fiber sensor home page’ (http://www fiber-sensor.com) for
the setting method of the OFF-delay, ON-delay and ONE
SHOT timer intervals.
(Note)
Note:The OFF-delay timer interval set in the PRO mode is displayed.
Refer to the ‘Fiber Sensor Guide Book’ or ‘SUNX fiber sensor home
page’ (http://www fiber-sensor.com) for more details.
• With the FX-301B(P)/G(P)/H(P), if jog switch and MODE
key are pressed for more than 3 sec. at the same time in
‘RUN’ mode condition, the key operations are locked, and
only the threshold value confirmation function or the adjust
function (valid only when the adjust lock function is
canceled) is valid.
• To cancel the lock function, press both the keys for more
than 3 sec. once again.
Wiring
• 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.
• 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 auto transformer 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
100 m 328.084 ft is possible with 0.3 mm
2
, or more, cable.
However, in order to reduce noise, make the wiring as
short as possible.
Others
• 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 water, oil, grease, or organic solvents, such as,
thinner, etc.
• This sensor cannot be used in an environment containing
inflammable or explosive gasses.
• Never disassemble or modify the sensor.
