J INSTALLING FIBER CABLES
Bends in Fiber cables
Pl astic and glass filament fiber cables may be bent to avoid
obstacles on the way to the sensing site. Here are some
guidelines about the location of cable bends: The first bend must
be as least 20 mm (0.79 in) away from where the cables enter
the amplifier. The last bend must be at least 20 mm (0.79 in)
bending the sensing head. We recommend a 25 mm (1.0 in)
minimum radius for a right angl e bend to maintain the rated
sensing distance. The sharpest all owable right angle bend is over
a 10 mm (0.39 in) radius, but this will result in a shorter sensing
distance. Refer to the bending radius graph.

Do not apply excess force on the Fi ber Units.
Do not pull or press the Fi ber Units. The Fiber U nits have a
withstand force of 1 kg or 3 kg (pay utmost attention because the
fibers are thin).
Do not bend the Fiber Uni ts beyond the permissible bending
radius.
Do not bend the edge of the Fiber Units.

Proper Supports for Cables
To support the fiber cable betw een the sensing site and the
amplifier, mount the cable using a nylon strap or cable tie. Do not
use a U-shaped strap that will compress or put stress on the fiber
cable. To prevent damage from excessive vibration, take up the
fiber in a loop as shown below.

App earance
The length can be ordered in increments of 1 m between
6 m min. and 20 m max. (2-m and 5-m fiber length types are
standard for E32-TC200, E32-DC200.)

Sensing distance will be reduced by approximately 25% when
fibers are connected.
Only fibers with 2.2 mm dia. can be connected.
