SMA990LV

Voltage: 10 to 250V ac
or 12 to 115V dc

Range: 6 inches to
30 feet (9m)

Beam: visible red, 650nm

SMA91ESR &
SMA99RSR

Voltage: 10 to 250V ac
or 12 to 115V dc;
("ESR": 10-250V ac/dc)

Range: 10 feet (3m)

Beam: infrared, 880nm;
visible red tracer beam

Effective beam: 0.14" dia.

A visible-red light beam reduces the potential for false signals from highly reflective
objects ("proxing") and simplifies alignment. The AG (anti-glare) model polarizes
the emitted light and filters out unwanted reflections,
making its use possible in
applications otherwise unsuited to retroreflective sensing (and where reduced
excess gain is acceptable). Maximum range with all units is attained when using the
model BRT-3 3" corner cube retroreflector. See the Banner product catalog for
details about available retroreflective materials.

VALU-BEAM 990 Series Sensors

Opposed mode sensors have higher excess gain than other models, and therefore
should be used whenever possible. Opposed mode is the most reliable sensing mode
for counting opaque materials. The small size of these sensors makes them ideal for
many conveyor applications, and their small effective beam size (particularly of the
ESR/RSR models) enables them to reliably count relatively small objects. ESR and
RSR models also have a wide beam angle for very forgiving alignment within the
10-foot range. VALU-BEAM opposed mode sensors have a visible red "tracer
beam" which greatly simplifies sensor alignment.
