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.
Flashing red LED in TEACH mode indicates
excess gain (AID circuit). Amber indicates
when sensor is ready to learn each condition.
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).

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.
