It is ideal for right-angle sensing in "tight" areas. The PBPS26U operates in the diffuse sensing mode. Sensing light is transmitted and received through an opening located in the side of the sensing probe near the tip (see drawing and photo). Objects are detected by the light they reflect back through the 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 end 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 two small 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. Fiber Cutting Information Description SENSING RANGE: A function of the sensor. For further information, contact your factory applications engineer. 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 sensor ("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). Additional Specifications 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: 0.5 inch (12 mm). The 2-inch long stainless steel side-view probe tip is non-bendable.

Install the plastic fiber optic assembly(s) as follows: 1) Prepare the sensor ends of the fibers (see page 1, bottom). 2) Unlock (slide up) the fiber gripper and insert the small fiber adaptor into the ports as far as it will go. 3) Gently insert the prepared plastic fiber sensor ends into the ports as far as they will go. Slide the fiber gripper down to lock. D12 Series D12 Series sensors for use with plastic fiber optic assemblies include sensors with the letters FP in their model number suffix.
