ENVIRONMENTAL FACTORS FOR PLASTIC FIBER OPTICS
OPERATING TEMPERATURE OF PLASTIC FIBER OPTIC
ASSEMBLIES: -30 to +70 degrees C (-20 to +158 degrees F).
CHEMICAL RESISTANCE OF PLASTIC FIBER OPTIC ASSEMBLIES:
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 optical fiber from most chemical environments; however, materials
may migrate through the jacket with long-term exposure. Samples of plastic
fiberoptic material are available from Banner for testing and evaluation.
FIBER OPTIC Mode (plastic fibers)
Plastic fiber optics are lower in cost than glass
fiber optics, and are ideal for use in situations
where environmental conditions allow (see in-
formation, below). They are easily cut to length
in the field, and are available in a variety of
sensing end styles. For further information,
refer to the Banner product catalog.

Q45XB6FQ
FIBER OPTIC Mode (glass fibers)
Model Q45XB6FQ has high excess gain (72"
range with IT23S fibers). As a result, opposed
individual fibers operate reliably in many very
hostile environments. Also, special miniature
bifurcated fiber optic assemblies with bundle
sizes as small as .020 inch (.5mm) in diameter
may be used successfully for diffuse mode
sensing. The excess gain curves and beam pat-
terns illustrate response with standard .060 inch
(1.5mm) diameter and .12 inch (3mm) diameter bundles.
Response for smaller or larger bundle sizes may be interpolated.
