Break-free, more flexible, square head fiber *!

*	These fibers provide a combination of break-free (10 million times bending durability [typical value, when bent back and forth at 180° with a bending radius of R10 mm R0.394 in]) and bendable (bending radius of R2 to R4 mm R0.079 to R0.157 in) characteristics.

Feb. 2014 New Suare head fiber: Oil resistant fibers

Features

Oil resistant fibers

・The fiber ber core will not harden or break, even in environments where oil is present.

<Full-protection type>

tough FT-R60Y (Thru-beam type)

High environmental resistance
The head, nut, and washer are made from rust-resistant SUS304. The unbreakable tough fiber with high durability is covered in a fluorine resin tube. The fiber head is also covered with a fluorine resin component, achieving a high level of environmental resistance.

Less susceptibility to oil adhesion thanks to fluorine resin
Fibers deliver stable detection, since the sensing part is sealed with fluorine resin, which does not allow oil penetration. Additionally, the detection part features a convex design made of fluorine resin, achieving lower friction than glass.

Resistant to oil and coolant
The fiber head and fiber cable are connected by the âfastening and caulkingâ method without using adhesives. This method eliminates concerns that adhesives will absorb moisture in high-humidity environments and damage the fiber. The enclosure achieves IP68G protection, so the fiber can be installed around metal processing machines shrouded in the oil mist.

<Cable-protection type>

tough FT-R44Y (Thru-beam type) / FD-R61Y (Reflective type)

Even stronger than tough fiber
The tough fiber has been reinforced by covering it with a fluorine resin tube so that it can be used even in harsh environments where oils and solvents are used. The fiber cable will not harden or break, even if it is splashed with oil.

IP67 rating
The head, nut, and washer are made from rust-resistant stainless steel (SUS304).

Compact, space-saving

Fiber can be installed at a minimum pitch of M3: 6.5 mm 0.256 in or M4: 8.5 mm 0.335 in using needle-nose pliers.

Introducing square R1 mm (R0.039 in) (sharp bending) fiber

FT-R41W/R42W
We now offer a sharp bending fiber featuring a low level of light fluctuations, even when bent at R1 mm R0.039 in. It is also available with a lens capable of long-range sensing.



・Resistant to dust and particulate matter. ・Tip dimensions can be shortened.

Compact installation

Square head fiber heads can be installed cleanly on the side of a conveyor belt.
The design makes it less likely for tools and other objects to catch on the fiber cable during installation.

Use for long-range sensing (With thru-beam type fiber) or spot detection (With reflective type fiber) by attaching a lens
