The powerful modulated
visible beam of this sensor
makes it compatible with
all Banner plastic fiber
optic assemblies. Banner
plastic fibers are an eco-
nomical alternative to glass
fibers when environmen-
tal conditions allow (see
below). Banner plastic fi-
ber optics are available in
two core diameters and
with various sensing tip
styles. Standard length is 6
feet. See the Banner prod-
uct catalog for more fiber
optic information.
SMA990LT
Voltage: 10 to 250V ac
or 12 to 115V dc
Range: 30 feet (9m)
Beam: infrared, 940nm
OPERATING TEMPERATURE OF FIBER OPTIC ASSEMBLIES: -30 to +70 C (-20 to +158 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 through the jacket
with long-term exposure. Samples of plastic fiber optic material are available from Banner for testing and
evaluation.
Environmental Factors for Plastic Fiber Optics
Models
VALU-BEAM model SMA990LT is designed specifically for "people counting".
Its strong (30 foot range) infrared beam is invisible to the eye, and a built-in 1/10
second on/off delay helps prevent multiple counts. Maximum retroreflective signal
strength is attained when using the model BRT-3 corner-cube retroreflector. Other
retroreflective materials may also be used (see Banner product catalog for descrip-
tive information).
VALU-BEAM convergent sensors produce a precise .06" diameter visible red
sensing spot at a focus point 1.5" in front of the sensor lens. Due to its very narrow
depth of field, this model excels at counting small objects only a fraction of an inch
away from backgrounds. This convergent sensor may be used for reliable counting
of some radiused products which flow past at a fixed distance from the sensor lens.
