Features
For use with leak detection or liquid detection fiber only
The FX-301-F7 (Note 1) dedicated for the leak detection fiber FD-F71 and the FX-301-F dedicated for the liquid detection fiber FT-F93 are available. Optimal setting is possible with easy operation.
Note: The FX-301-F can be also used by setting it to leak detection mode. However, the functions are different from the FX-301-F7 dedicated for the leak detection fiber, so it is recommended to use the FX-301-F7 when using the leak detection fiber.
Easy maintenance, as main and sub units are identical
Both main and sub units utilize the same amplifier body. This feature allows for easy mounting in the side-by-side configuration. The main and sub unit functions are distinguished only by the proper use of 3-core main cable and the 1-core sub cable.
Moreover, by utilizing the same body for both main and sub units, inventory management and maintenance is simplified.
Sets the optimal threshold value [FX-301-F7]
Threshold value will be set automatically to -20 % of the incident light intensity during the teaching to steadily detect the leak. It is also possible to change the threshold value to -15 % or -30 %.

Threshold follow-up function [FX-301-F7]
Incident light intensity is checked at regular time interval (10 min.), and threshold value is reset automatically.
*Function is set to OFF at the time of factory shipment.

Flashing function incorporated
When the leak detection fiber is connected (F7 mode), if a leak is detected, you will recognize which fiber detects the leak at a single glance because the emitter will start flashing.
Long life and stable operational settings due to the newly developed emitting element
The newly developed “four-chemical emitting element” used for FX-301-F7 / FX-301-F can suppress the secular change of the light emitting element to minimum, allowing stable detection for long period of time.
Easy to operate with individual / collective teaching mode
Individual teaching mode (TEACH)
Optimal threshold value is set automatically on FX-301-F7 just by setting the MODE indicator to “TEACH” and pressing the jog switch.
(The threshold value is set after selecting the liquid detection fiber for FX-301-F.)
Collective teaching mode (ALL)
Teaching is performed collectively for all the connected amplifiers with an optical communication function when the MODE indicator is set to “ALL”. Each amplifier will be set with an optimal threshold value.
At the same time, other setting in the master unit will be copied to the slave unit.
Low profile liquid detection fiber with high chemical resistance
■Labor-saving design
・Because all you need to install is one screw, one-touch mounting of the fiber head is possible.
・Replacement parts even for resetting after a leak are unnecessary.
・Because the fiber head is simply designed, wiping off leaks is rendered easy.
■Superb explosion resistance / chemical resistance
Explosion resistance is enhanced by adopting the fiber method (SEMI S2 compliant)(Note 1). The head unit made of fluorocarbon polymers also has superb chemical resistance.
(Note 1) :
The design takes into account the environmental testing required by SEMI S2.
To ensure that the final system complies with the standards, you must design and use it in accordance with relevant standards, regulations, and regulations.
■Stable detection performance
The unique effect of capillarity enables reliable detection of small leaks and viscous liquids.
■Compact, space-saving
This slim (10 mm 0.394 in) side-mounting fiber head is especially good for use in confined spaces.
■Amplifier built-in type photoelectric sensor is also line-up [EX-F70 / EX-F60]
Refer to "Leak Detection Sensor EX-F70/EX-F60" for details.
Stably detect the liquid inside the pipe!
■Stable design that doesn’t permit liquid-absent or sensor errors
・When liquid is present, its effect on the lens causes light to focus and enter.
・When abnormalities such as a severed or removed fiber or a cutoff cable occur, light does not enter and the sensor will output the same as “liquid-absent”.
■Superior explosion resistance compatible to SEMI S2 (Note 1)
Because there is no electric circuitry in the fiber head, it boasts excellent explosion resistance.
(Note 1) :
The design takes into account the environmental testing required by SEMI S2.
To ensure that the final system complies with the standards, you must design and use it in accordance with relevant standards, regulations, and regulations.
■Easy to use and reliable detection
Even when the shape and thickness of the pipe vary, this fiber head uses a method where the beam axis follows the diameter of the pipe, and so when compared to conventional methods, the shape and thickness of the pipe have no influence over the performance of this fiber head.
■Reliable detection not affected by bubbles or droplets
Latest optical fiber techniques have solved problems caused by bubbles, droplets or liquid leakage that arise in conventional pipe-mountable fiber heads.

Wiring
- Wiring tasks and expansion tasks must be performed with the power off.
- 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 product 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.
- Make sure to use an isolation transformer for the DC power supply. If an autotransformer (single winding transformer) is used, this product or the power supply may get damaged.
- When a surge occurs in the power used, absorb the surge with a surge absorber connected to the power source.
- Take care that short circuit of the load wrong wiring may burn or damage the product.
- 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 100 m 328.084 ft is possible with 0.3 mm2, 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 lamp from a rapid-starter lamp, a high frequency lighting device or sunlight etc., as it may affect the sensing performance.
- Do not use this sensor in places having excessive vapor, dust, etc., or where it may come in contact with corrosive gas.
- When the fiber head gets dusty or dirty etc. the sensitivity deteriorates. To keep stable detection, wipe the fiber head to remove dust or dirt etc. and carry out sensitivity teaching periodically.
- These sensors are only for indoor use.
- Take care that the product does not come in contact with oil, grease, organic solvents, such as thinner, etc., strong acid or alkaline.
- This sensor cannot be used in an environment containing inflammable or explosive gases.
- Never disassemble or modify the sensor.
- EEPROM is adopted to this product. It is not possible to conduct teaching 100 thousand times or more, because of the EEPROM's lifetime.
