Scanner block 2SBF1 com-
bines the simplicity of 2-
wire hookup with the so-
phistication and versatility
of optical fibers. The infra-
red source of this model will
work with any Banner glass
fiber optic assembly, except
bifurcated assemblies with
bundle diameters less than
1/16". Since fibers are fre-
quently used for sensing
small parts, fast response
time is often a considera-
tion. If the application re-
quires response near the 10
millisecond specification of
the 2SBF1, consider the
faster 3- & 4-wire model
SBF1.

Models 2SBD1 and 2SBDX1 diffuse (proximity) mode scanner blocks are identical except for their lenses. Model
2SBD1 uses upper cover model UC-D, and the 2SBDX1 uses UC-L (see MULTI-BEAM Accessories, pages 30-
31). While the UC-L lens extends the range to over 30 inches, it creates a "dip" in the excess gain at closer ranges.
As a result, the 2SBDX1 may sense a dark colored object at 10 inches, but it may not see it at all at 2 inches. If
the application is not completely defined, either scanner block may be ordered, along with the complementary
upper cover as an accessory.
