Excessive vibration can break the fiber head. Use the following
method to prevent fiber head breakage.
A one-turn loop can
absorb vibrations.

Bending Radius
E39-F11 Sleeve Bender
The bending radius of the stainless steel tube should be as large
as possible. The smaller the bending radius becomes, the shorter
the sensing distance will be.
Insert the tip of the stainless steel tube to the Sleeve Bender and
bend the stainless steel tube slowly along the curve of the Sleeve
Bender (refer to the figure).

E39-F32j Protective Spiral Tubes
Insert a fiber to the protective spiral tube from the head connector
side (screwed) of the tube.

tube
Push the fiber into the protective spiral tube. The tube should be
straight so that the fiber is not twisted when inserted. Then turn
the end cap of the spiral tube.

other than the end cap, apply tape to the tube so that the portion
becomes thicker in diameter.

Each fiber unit should be as close as possible before they are
connected.
Sensing distance will be reduced by approximately 25% when
fibers are connected.
Only 2.2-mm-dia. fibers can be connected.
