Banner Plastic fiber optic assemblies
B anner plastic fiber optic assemblies are available either straight or coiled, individual or
bifurcated, and with a variety of sensing tip styles (see photo). Models compatible with
PC44 Series modules include the full line of Banner .040" core diameter plastic fibers:
PBF46U straight bifurcated fiber, ferruled sensing tip (for diffuse sensing)
PBP46U straight bifurcated fiber, bendable probe sensing tip (for diffuse sensing)
PBP46UC coiled bifurcated fiber, bendable probe sensing tip (for diffuse sensing)
PBT46U
straight bifurcated fiber, threaded sensing tip (for diffuse sensing)
PBT46UC coiled bifurcated fiber, threaded sensing tip (for diffuse sensing)
PIF46U
straight individual fiber, ferruled sensing tip (for opposed sensing)
PIP46U straight individual fiber, bendable probe sensing tip (for opposed sensing)
PIP46UC coiled individual fiber, bendable probe sensing tip (for opposed sensing)
PIT46U
straight individual fiber, threaded sensing tip (for opposed sensing)
PIT46UC coiled individual fiber, threaded sensing tip (for opposed sensing)
NOTES: Individual fibers are sold in pairs. For further information about Banner
plastic fiber optic assemblies, request product data sheet P/N 32881.
Banner plastic fiber optics are an economical alternative to glass
fiber optics for piping photoelectric sensing light into and out of
confined areas where the environmental conditions allow.
They are offered in two general styles: individual and bifurcated.
Individual (PI Series) fibers are used in pairs in the opposed sensing
mode. One fiber transmits the light to the sensing location, while
the other fiber returns the received light to the sensor.
Bifurcated (PB Series) plastic fiber assemblies are "two-way"
fibers having a single sensing end that both emits and receives light
and dual control (sensor) ends which attach separately to the
sensor. Plastic fiber optic assemblies are available in a variety of
sensing end styles. Coiled assemblies may be used successfully on
reciprocating mechanisms for millions of cycles.
Banner plastic fiber optic assemblies are available in two monofila-
ment core diameters: .020-inch and .040-inch. PC44 Series
modules require .040-inch core fibers.
Banner standard plastic fiber optic assemblies are unterminated on
the control (sensor) end. Fiber assemblies are approximately 6 feet
(2m) in length. They can be used "as-is", or they may be cut to a
shorter length. Each assembly is supplied with a cutting device to
allow the fiber to be easily cut to length. Cutting instructions are
included with the fiber assembly.
Due to their light transmission properties, plastic fiber optics are
recommended for use only with visible light fiber optic sensors.
SENSING RANGE: refer to the excess gain curves for the fiber optic sensor
to be used. The selection charts at the front of the Banner product catalog list
all self-contained fiberoptic sensors and page references for gain curves.
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 below) 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).
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 environ-
ments. 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: 1.0 inch (25mm) for .040 inch diameter fibers.
CONSTRUCTION:
OPTICAL FIBER: plastic monofilament
PROTECTIVE JACKET: black polyethylene
THREADED END TIPS and HARDWARE: nickel-plated brass
PROBE END TIPS: annealed (bendable) T304 stainless steel
ANGLED END TIPS: hardened T304 stainless steel
FERRULED END TIPS: T303 stainless steel
