Automatic selection of the optimal LED
Two detection modes can be selected from to suit the application
Mark mode
Ultra high-speed response
This sensing mode automatically selects
a single color from the 3 R•G•B LEDs
to realize an ultra quick 45 μs response
time. The automatic optimal LED
selection function automatically selects
the LED that is most suitable for the
sensing. This function is perfect for ultra
quick sensing.
The color around letters is
detected as a mark.
Predetermined colors are
detected as marks.
* You can select the mark mode or color mode through key operation.
Color mode
High precision discrimination
All 3 R•G•B LEDs light up and high
precision mark color discrimination
occurs using the R•G•B refl ective light
ratio. This function enables effective
detection of fi lms with patterns around
the area of the mark.
High precision mark color discrimination
The color mode on the LX-100 series utilizes all 3 R•G•B LEDs to determine the R•G•B ratio of the mark color.
The built-in 12-bit A/D converter enables high precision 1/4,000-resolution judgments. The fi gure below is a graphic
description of this process.
Even similar colors are accurately determined using the R•G•B ratio.
