Banner VALU-BEAM Series - Manual (Page 5)

SMA91E &SM2A91R
Voltage: 24 to 250V ac,
("E": 10-250V ac/dc)
Range: 200 feet (60 m)
Response: 8ms on/4 off
Beam: infrared, 880nm
Effective beam: 0.5" dia.
RETROREFLECTIVE
OPPOSED Mode
A visible-red light beam reduces the potential for false signals from highly
reflective objects ("proxing") and simplifies alignment. AG (anti-glare) models
polarize the emitted light and filter out unwanted reflections, making their use
possible in applications otherwise unsuited to retroreflective sensing (when
reduced excess gain is acceptable). Maximum range with "LV" units is attained
when using the model BRT-3 3" corner cube reflector. For details on retroreflec-
tive target materials, see the Banner product catalog.

Beam Pattern Sensing Mode
Opposed mode sensors have higher excess gain than other models, and
therefore should be used whenever possible. 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 detect relatively small objects. VALU-BEAM opposed mode
sensors have a visible red "tracer beam" which greatly simplifies sensor
alignment. ESR/RSR models have a wide beam angle for very forgiving
alignment within the 10 foot range. E/R models have a narrow beam
spread and should be used when it is important to minimize optical
"crosstalk" between adjacent emitter-receiver pairs at close range in
multiple sensor arrays.
