Resumen del manual
The MINI-BEAM Expert is available in many sensing modes to solve virtually every sensing application in your plant. Sensing modes include: regular and wide angle diffuse (proximity mode), polarized retroreflective, retroreflective mode clear object detection, convergent, plus infrared and visible beam fiber optics. See page 6 for available models and specifications. Retroreflective Convergent Fiber Optic The world’s most popular photoelectric is now the world’s smartest.The world’s most popular photoelectric is now the world’s smartest. MINI-BEAM®: Millions of sensors in use. The MINI-BEAM is the world’s most popular miniature photoelectric sensor. With millions of units in use worldwide, it has become the benchmark for small photoelectrics. Fact is, there are more MINI-BEAMs solving more sensing applications in more plants worldwide than any other sensor. Because there is a MINI-BEAM to solve every application in your plant, it is also your best single-sensor choice to standardize all of your sensing applications. Advanced “TEACHABLE” microprocessor. The new MINI-BEAM® Expert™* features a highly advanced, “teachable” microprocessor. With the sensor in TEACH mode, it can “learn” the ON and OFF sensing conditions required, compute the most accurate setting for recognizing the difference in received light signals, and self-program that setting. *Patent pending Simple, one-button operation. The MINI-BEAM Expert “learns” each job with the push of a single button. Simply push it once with the sensor pointed at the ON condition, and once with it pointed at the OFF condition. Not only does it provide extremely accurate sensitivity settings, this single pushbutton is extremely easy to use, and it eliminates the potential for adjustment tampering on your production line.Diffuse MINI-BEAM®™: Push one button to solve your toughest applications.MINI-BEAM® ™: Push one button to solve your toughest applications.ExpertExpert MINI-BEAM®™: Push one button to solve your toughest applications.MINI-BEAM® ™: Push one button to solve your toughest applications.ExpertExpert 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). 4 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.
