.04" diameter coiled bifurcated fiber with threaded sensing endPlastic Fiber Optic Assembly model PBT46UCPBT46UC p/n 26086This Banner plastic fiber is designed to be cut by the customer to the length required for the application. Tofacilitate 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 theapplication. At the control end of the fiber, separate the two fibers. Lift the top (blade) of the cutter toopen the cutting ports. Insert one of the control ends through one of the four large cutting ports on thePFC-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, cutthe second control end to the same length as the first. Separate the cut ends for a length of 2 to 3 inchesto 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 datasheet packed with the sensor, or refer to the Banner product catalog.TEMPERATURE EXTREMES: Temperatures below -30°C will cause embrittlement ofthe plastic materials but will not cause transmission loss. Temperatures above +70°Cwill cause both transmission loss and fiber shrinkage.REPEAT BENDING/FLEXING: Life expectancy of plastic fiber optic cable is in excessof one million cycles at bend radii of no less than the minimum (stated at right) and abend 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 arerecommended 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 bedamaged by contact with acids, strong bases (alkalis) and solvents. The polyethylenejacket will protect the fiber from most chemical environments. However, materials maymigrate through the jacket with long term exposure. Samples of fiber optic materialare available from Banner for testing and evaluation.MINIMUM BEND RADIUS OF PLASTIC FIBER: 1.0 inch (25 mm)CONSTRUCTION:OPTICAL FIBER: acrylic monofilamentPROTECTIVE JACKET: black polyethyleneTHREADED END TIP and hardware: nickel plated brassFiber Cutting InformationAdditional SpecificationsPrinted in USA p/n 03433L4BModel PBT46UC is a bifurcated coiled plastic fiber optic assembly withan M6 x 0,75mm threaded nickel plated brass sensing end. Coiled plasticfibers are especially suited to applications requiring repeated flexing (re-ciprocating motion).The PBT46UC operates in the diffuse sensing mode. Sensing light istransmitted and received through the threaded fiber sensing end. Objectsare detected by the light they reflect back through the sensing end. Fibercore 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.
