.04" diameter bifurcated fiber with threaded sensing end
Plastic Fiber Optic Assembly model PBT46U
PBT46U p/n 25967
This Banner plastic fiber is designed to be cut by the customer to the length required for the ap-
plication. To facilitate cutting, a Banner model PFC-2 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-2 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.
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
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.
MINIMUM BEND RADIUS OF PLASTIC FIBER: 1.0 inch (25 mm)
CONSTRUCTION:
OPTICAL FIBER: acrylic monofilament
PROTECTIVE JACKET: black polyethylene
THREADED END TIP and hardware: nickel plated brass
Model PBT46U is a bifurcated plastic fiber optic assembly with an M6 x 0,75mm
threaded nickel plated brass sensing end.
The PBT46U operates in the diffuse sensing mode. Sensing light is transmitted and
received through the threaded sensing end. Objects are detected by the light they
reflect back through the sensing end. Fiber core diameter is .04 inch.
The PBT46U 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.
