.02" diameter bifurcated fiber with side-view probe sensing endPlastic Fiber Optic Assembly model PBPS26UPrinted in USA p/n 36377Model PBPS26U is a bifurcated plastic fiber optic assemblywith a 2-inch long non-bendable side-view probe type sensingend. It is ideal for right-angle sensing in "tight" areas.The PBPS26U operates in the diffuse sensing mode. Sensinglight is transmitted and received through an opening locatedin the side of the sensing probe near the tip (see drawing and photo). Objects are detected by the light they reflect back throughthe opening. Fiber core diameter is .02 inch. NOTE: The probe tip is non-bendable.The PBPS26U may be used with plastic fiber optic sensors from the following Banner sensor families: D12, OMNI-BEAM,MAXI-BEAM, VALU-BEAM, Q45, MINI-BEAM, and ECONO-BEAM. See page 2 for further information.PBPS26U p/n 35042(non-bendable)Non-bendable side-view probe sensing endThis Banner plastic fiber is designed to be cut by the customer to the length required for theapplication. To facilitate cutting, a Banner model PFC-1 cutting device is suppliedwith this fiber. Cut the fiber as follows:1) Locate the "control end" of the fiber (the unfinished end). Determine the lengthof fiber required for the application. At the control end of the fiber, separate the twofibers. Lift the top (blade) of the cutter to open the cutting ports. Insert one of thecontrol ends through one of the two small cutting ports on the PFC-1 cutter so that theexcess 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 cut-ting port, cut the second control end to the same length as the first. Separate the cut ends for a length of2 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.Fiber Cutting InformationDescriptionSENSING RANGE: A function of the sensor.For further information, contact your factory applications engineer.TEMPERATURE EXTREMES: Temperatures below -30°C will causeembrittlement of the plastic materials but will not cause transmission loss.Temperatures above +70°C will cause both transmission loss and fibershrinkage.REPEAT BENDING/FLEXING: Life expectancy of plastic fiber optic cableis 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 wherethe cable enters the sensor ("control end") and at the sensing end tip. Coiledplastic fiberoptic assemblies are recommended for any application requiringreciprocating fiber motion.OPERATING TEMPERATURE: -30 to +70°C (-20 to +158°F).Additional SpecificationsCHEMICAL RESISTANCE: The acrylic core of the monofilament opti-cal fiber will be damaged by contact with acids, strong bases (alkalis) andsolvents. The polyethylene jacket will protect the fiber from most chemicalenvironments. However, materials may migrate through the jacket with longterm exposure. Samples of fiber optic material are available from Banner fortesting and evaluation.MINIMUM BEND RADIUS OF PLASTIC FIBER: 0.5 inch (12 mm).The 2-inch long stainless steel side-view probe tip is non-bendable.CONSTRUCTION:OPTICAL FIBER: acrylic monofilamentPROTECTIVE JACKET: black polyethylenePROBE END TIP: hardened (non-bendable) T304 stainless steel
