Model PBPS26U

 is a bifurcated plastic fiber optic assembly 

with a 2-inch long non-bendable side-view probe type sensing 
end.  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.

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 cut-
ting 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 opti-

cal 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.

 

CONSTRUCTION:  

OPTICAL FIBER: acrylic monofilament

PROTECTIVE JACKET:  black polyethylene

PROBE END TIP: hardened (non-bendable) T304 stainless steel
