and rate sensing logic functions
Most scanner blocks include Banner's exclusive, patented
AID™ (Alignment Indicating Device) system, which lights a
top-mounted indicator LED whenever the sensor sees its
own modulated light source, and pulses the LED at a rate
proportional to the strength of the received light signal.

The duration of the pulse is independent of the duration of the input signal. The output pulse of the LM4-2NR must complete before it recognizes another input transition. This is called a "non-retriggerable" one shot, which sometimes offers an advantage in indexing or registration control applications where multiple input signals are possible during advance of the product ...
