Banner VALU-BEAM Series - Manual (Page 13)

Beam Pattern Sensing Mode
The powerful modulated vis-
ible beam of these sensors
makes them compatible with
all Banner plastic fiber optic
assemblies, and their fiber
fittings will accomodate both
terminated and unterminated
type assemblies. Plastic fi-
bers are ideal for short-range
sensing where the environ-
ment is not severe. Plastic
fiber optic model information
may be found in the Banner
product catalog
These sensors will also inter-
face with Banner glass fiber
optic assemblies.

Environmental Factors for Plastic Fiber Optics
OPERATING TEMPERATURE OF FIBER OPTIC ASSEMBLIES: -30 to
+70 degrees C (-20 to +158 degrees F).
CHEMICAL RESISTANCE OF 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 throught the jacket with long-term exposure. Samples of plastic fiber
optic material are available from Banner for testing and evaluation.

Fiber optic sensing is often
the answer when, due to space
or environmental limitations,
the sensor itself cannot be
placed at the actual sensing
position. These sensors' pow-
erful modulated infrared
beam is compatible with all
Banner glass fiber optics in
the opposed, retroreflective,
and diffuse sensing modes.
Banner glass fiber optic se-
lection information may be
found in the product catalog.
Sensor/fiber interface is wa-
terproof to maintain complete
sensing system moisture re-
jection.
