Description
Model PBT46UC is a bifurcated coiled plastic fiber optic assembly with
an M6 x 0,75mm threaded nickel plated brass sensing end. Coiled plastic
fibers are especially suited to applications requiring repeated flexing (re-
ciprocating motion).
The PBT46UC operates in the diffuse sensing mode. Sensing light is
transmitted and received through the threaded fiber sensing end. Objects
are detected by the light they reflect back through the sensing end. Fiber
core diameter is .04 inch.
The PBT46UC may be used with plastic fiber optic sensors from the following Banner sensor families: D12, OMNI-BEAM, MAXI-
BEAM, VALU-BEAM, Q45, PC44, MINI-BEAM, and ECONO-BEAM. See page 2 for further information.
Additional Specifications
SENSING RANGE: A function of the sensor. For further information, see the data
sheet packed with the sensor, or refer to the Banner product catalog.
TEMPERATURE EXTREMES: Temperatures below -30°C will cause embrittlement of
the plastic materials but will not cause transmission loss. Temperatures above +70°C
will cause both transmission loss and fiber shrinkage.
REPEAT BENDING/FLEXING: Life expectancy of plastic fiber optic cable is in excess
of one million cycles at bend radii of no less than the minimum (stated at right) and a
bend of 90 degrees or less. Avoid stress at the point where the cable enters the sen-
sor ("control end") and at the sensing end tip. Coiled plastic fiberoptic assemblies are
recommended for any application requiring reciprocating fiber motion.
OPERATING TEMPERATURE: -30 to +70°C (-20 to +158°F).
CHEMICAL RESISTANCE: The acrylic core of the monofilament optical fiber will be
Fiber Cutting Information
This Banner plastic fiber is designed to be cut by the customer to the length required for the application. To
facilitate cutting, a Banner model PFC-1 cutting device is supplied with this fiber. Cut the fiber as follows:
1) Locate the "control end" of the fiber (the unfinished end). Determine the length of fiber required for the
application. At the control end of the fiber, separate the two fibers. Lift the top (blade) of the cutter to
open the cutting ports. Insert one of the control ends through one of the four large cutting ports on the
PFC-1 cutter so that the excess fiber protrudes from the back of the cutter.
2) Double-check the fiber length, and close the cutter until the fiber is cut. Using a different cutting port, cut
the second control end to the same length as the first. Separate the cut ends for a length of 2 to 3 inches
to allow proper attachment to the sensor.
3) Gently wipe the cut ends of the fiber with a clean, dry cloth to remove any contamination.
Do not use solvents or abrasives on any exposed optical fiber. Do not use a cutting port more than once.
The blade may tend to dull after one cut.

damaged by contact with acids, strong bases (alkalis) and solvents. The polyethylene
jacket will protect the fiber from most chemical environments. However, materials may
migrate through the jacket with long term exposure. Samples of fiber optic material
are available from Banner for testing and evaluation.
