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.
