FIBER OPTIC Mode
(glass fiber optics)
OPPOSED FIBER OPTIC
Mode (glass fiber optics)
Model SBFX1 is the first choice for glass fiber optic applications, except in fiber optic retroreflective applications
or where faster response speed or visible light are a requirement. Model SBFX1 contains both emitter and receiver
and thus accepts either one bifurcated fiberoptic assembly or two individual fiber optic cables. The excess gain
of model SBFX1 is the highest available in the photoelectric industry. 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 with model SBFX1 for diffuse
mode sensing. The excess gain curves and beam patterns 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.
NOTE: opposed ranges shown are meant to illustrate excess gain only, and are limited by fiber length. Use scanner
block models SBEXF and SBRXF1 (above) for long range opposed fiber optic sensing.
SBEF & SBRF1
Range:
see excess gain curve
Response: 1ms on/off
Repeatability: 0.03ms
Beam: infrared, 880nm
NOTE: fiber optic gain
curves apply to 3-foot fiber
lengths. Gain decreases by
approximately 10% for each
additional foot of fiberoptic
cable.

SBFX1
SBEF & SBRF1: use with individual glass fiber optic assemblies in lieu of model SBF1 where it is inconvenient
to run fibers from a single scanner block.
SBEXF & SBRXF1: use in place of model SBFX1 (shown below) for long-range opposed fiber optic sensing.
Or use where high excess gain is required and it is difficult to run the fibers to both sides of the process from a single
scanner block. Lenses for fiber optics are shown in the Banner product catalog.
