MINI-BEAM Expert : Push one button to solve your toughest applications.
Precise, low-contrast sensitivity adjustments.
The MINI-BEAM Expert recognizes the most difficult low-contrast
sensing conditions, and automatically expands its sensitivity
range to compute the most accurate setting for differentiating
even small differences in the received light signals. It is the most
accurate system available and will solve tough applications such
as white materials on a white background, small components,
edge detection, sensing small or lightly tinted color marks, and
transparent materials (see below).
Increased reliability for sensing
clear and reflective materials.
The MINI-BEAM Expert offers vastly increased
reliability versus standard sensors, for sensing
transparent and highly reflective materials, such
as plastic, shrink-wrap, clear plastic webs, bottles
and numerous other applications. The specialized
retroreflective clear object detection model
optically improves sensing contrast with clear
target materials such as glass.
Accurate indicators for excess gain
and sensing contrast stability.
In TEACH mode, the patented Banner Alignment
™
Indicating Device (AID ) superimposes a pulse
rate proportional to the strength of the received light
signal. After programming, when the sensor returns
to the RUN mode, the display provides an ongoing
indication of contrast stability at a glance.
In TEACH mode:
Flashing red LED in TEACH mode indicates
excess gain (AID circuit). Amber indicates
when sensor is ready to learn each condition.
In RUN mode:
Solid green LED indicates acceptable sensing
contrast. Amber indicates output ON.
Flashing green LED indicates sensing
contrast “marginal.”
Alternating red/green LED flashes in
the unlikely event of memory failure
(need to re-TEACH sensor).

MINI-BEAM
Remote programming for convenience and greater security.
Wherever they are mounted, one or more MINI-BEAM Expert sensors can
be easily wired to an external switch or PLC to enable remote programming
from a convenient location. Remote programming also assures greater
security for application settings because it can lock out the sealed
programming button, and there are no easily changed external switches.
Red, green or blue LED emitters.
The choice of a red, green, or blue LED light source in both
plastic and glass fiber optics, as well as convergent mode, gives
users the ideal sensing solution for maximum sensitivity to
any color, even low-contrast targets such as glass, or yellow ink
on a white background. This wide choice of models gives you
solutions to all your color mark applications.
Electrically protected.
The MINI-BEAM Expert withstands electrical problems
including reverse polarity, fast-transient and over-voltage.
It provides bipolar NPN and PNP (current sinking and
sourcing) outputs with a maximum rating of 150 mA (25°C)
to 100 mA (70°C).
Rugged and sealed.
MINI-BEAM Expert withstands difficult environments.
It’s yellow glass-filled polyester housing is rugged,
and its electronics are completely
encapsulated in epoxy. The
environmentally sealed programming
button eliminates leakage and
tamper-prone access covers and
adjustments. It is rated IEC IP67
and NEMA 6.
Prewired or QD wiring, 10 to 30V dc.
Users can choose 10 to 30V dc models with a 2 m (6.5') or 9 m (30')
attached, 5-conductor PVC potted-in cable, or a 5-pin Euro-style quick-
disconnect connector for easy sensor installation and removal. Keyed
connectors prevent wiring errors.

MINI-BEAM Expert Sensor Applications
CLEAR BOTTLE COUNTING
Objective: To reliably count clear bottles moving on a high-speed
conveyor line.
Sensor: SME312LPC
Operation: The polarized retroreflective optics of MINI-BEAM
Expert clear object detection sensors are optimized
for reliable sensing of clear glass or plastic materials.
This sensor generates one solid count from each
bottle moving through the beam.
WEB CUTOFF REGISTRATION
Objective: To detect a color mark printed on a continuous web
for accurate control of downstream cutoff.
Sensor: SME312CVB
Operation: MINI-BEAM Expert Model SME312CVB is a convergent
mode sensor with a blue light source that reliably detects
many difficult color mark contrasts, such as yellow against
off-white (shown here). The sensor is located near the
printing drum, where web “flutter” is not a factor. The
MINI-BEAM should be mounted at a “skew”angle of about
15 degrees from the perpendicular to shiny or clear webs in
order to avoid strong direct reflections of the sensing beam.
The MINI-BEAM Expert is available in fixed-wavelength
models with blue, green, or red light sources for handling
specific color contrasts.
WAFER CASSETTE PRESENCE
Objective: To sense the presence of wafer cassettes on a conveyor.
Sensor: SME312FP with PIT46U fibers and L2 lenses
Operation: Silicon wafers are transported in cassettes from one
location to another on a conveyor. Individual plastic
fiber optics are located on both sides of the conveyor
in the opposed sensing mode. L2 lenses are fitted onto
each fiber sensing tip to extend sensing range. The beam
is broken whenever a cassette is present.

Banner fiber optics allow you to “pipe” light into otherwise
inaccessible or hostile environments. Banner has the broadest, most
readily available line of fibers in the world. Choose from a huge
selection of standard fibers in virtually all shapes and sizes, or
custom fibers can easily be designed for your unique applications.
Choose from two general styles: individual fibers are used in pairs
in the opposed sensing mode; and bifurcated fibers that both emit
and receive light signals in one assembly. Banner plastic fibers
offer a uniquely affordable solution because they are inexpensive
and are easily cut to length during installation (a cutting device is
supplied with each fiber). Banner glass fibers withstand the most
hostile environments such as high temperatures up to 480°C
(900°F), corrosive materials, extreme moisture, high levels of
electrical noise, shock, and vibration. Request the Banner
Sensor Catalog (P/N 98000) or CD ROM (P/N

rate the range of Banner retroreflective sensors, however
new high-reflectivity models dramatically increase the
