It is a fiber with superior light intensity stability and

FX-500 series amplifier. FT-40
It offers stable sensing with an extremely small beam
axis curvature and gap.

Digital management is simple due to small differences in body.

When connected with the FX-500 series amplifiers, it has up to
4 times improved stability of incident light intensity compared

More user-friendly, high quality fiber
Stainless steel fittings are used for the fiber
head of all models. Improved centering accuracy
The beam axis deviation of each unit is kept
• Clearly conforms to RoHS SUS
within ±3º and the beam axis centering accuracy
• Can be used for secondary battery
is kept within ±150 μm 0.006 mil.
• Improved mounting strength
(Within ±5º and ±90 μm 0.004 mil for ultra small
* Except for FT-140
diameter fibers)
• Makes beam axis adjustment easier
Application • Improves mounting hole machining accuracy
• Improves sensing accuracy
Detecting a presence of a workpiece

FD-32G

Improved specularity
High precision polishing is accomplished by using
the PCTC polishing technique.
The specularity of the end face of the fiber is 5
times greater.
• Light intensity is increased, enabling stable
sensing.

Notes: 1) Note that the sensing range of the free-cut type fiber may be reduced by 20 % max. depending upon how the fiber is cut.
2) The fiber cable length practically limits the sensing range.
3) The sensing range is the possible setting range for the attached reflector. The fiber can detect an object less than setting range for the reflector.
Refer to p.32 or p.47 for the sensing range when FR-Z50HW is used in combination with a reflector (optional).
4) The sensing range is specified for white non-glossy paper.

It is a fiber in which the sensing distance is limited to a
specific range so it is not easily affected by the
background. It is effective when a workpiece is
accumulated or when the background is near.

Note: The sensing range is the possible setting range for the reflector. The fiber can detect an object less than 100 mm 3.937 in. However, note that if there are
any white or highly-reflective surfaces near the fiber head, reflected incident light may affect the fiber head. If this occurs, adjust the threshold value of the
amplifier unit before use.

Notes: 1) Be careful when installing the thru-beam type fiber equipped with the lens, as the beam envelope becomes narrow and alignment is difficult.
2) The fiber cable length practically limits the sensing range.
3) Refer to previous page for the ambient temperature of fibers to be used in combination.
4) The fiber cable length for the FT-H30-M1V-S is 1 m 3.281 ft. The sensing ranges in HYPR, U-LG and LONG of FX-500 / FX-550 series, in FX-102 take
into account the length of the FT-J8 atmospheric side fiber.

Notes: 1) ‌Note that the sensing range of the free-cut type fiber may be reduced by 20 % max. depending upon how the fiber is cut.
The sensing range of FR-KZ22E is specified for the attached reflector. The sensing range of FR-KZ50E and FR-KZ50H is specified for the attached
reflector RF-003. The sensing range of FR-Z50HW is specified for the attached reflective tape RF-13.
2) ‌The sensing range of retroreflective type is the possible setting range for the attached reflector. The fiber can detect an object less than setting range
for the reflector. However, note that if there are any white or highly-reflective surfaces near the fiber head, reflected incident light may affect the fiber
head. If this occurs, adjust the threshold value of the amplifier unit before use.

Notes: 1) Note that the sensing range of the free-cut type fiber may be reduced by 20 % max. depending upon how the fiber is cut.
2) The
‌ sensing range is the value for white non-glossy paper (as for FD-H30-L32 50 × 50 mm 1.969 × 1.969 in glass substrate).
3) The
‌ sensing range is specified for transparent glass 100 × 100 × t0.7 mm 3.937 × 3.937 × t0.028 in (FD-L21 and FD-L21W: t2 mm t0.079 in) [FD-L10:
silicon wafers 100 × 100 mm 3.937 × 3.937 in].
4) Sold
‌ as a set comprising vacuum type fiber + photo-terminal (FV-BR1) + fiber at atmospheric side (FT-J8).
5) Liquid inflow prevention joint, protective tube extension joint, fiber mounting joint are available. Please refer to p.42 for details.

: Models which can have extended sleeve

: Models which can have extended protective tube (fluorine resin)
: Models which can have extended stainless jacket sheath
Notes: 1) Note that the sensing range of the free-cut type fiber may be reduced by 20% max. depending upon how the fiber is cut.
2) The fiber cable length practically limits the sensing range.
3) Applicable protective tube length is up to 10 m 32.808 ft and in units of 0.5 m 1.640 ft.
4) The allowable cutting range is 500 mm 19.685 in from the end that the amplifier inserted.
