Precise, low-contrast sensitivity adjustments.
The MINI-BEAM Expert recognizes the most difficult low-contrast sensing conditions, and automatically expands its sensitivity 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 retroflective 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 (AIDTM) superimposes a pulse 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).
