Features
Can detect any mark!
Coaxial reflective optics and a sharp 1 x 5 mm 0.039 x 0.197 in spot enable high precision sensing. Stable detection of marks is possible.
Automatic optimal LED selection function
The 3 colors of the R・G・B LEDs are optimally selected according to the color combination. With the LX-100’s Mark mode, the built-in “Automatic optimal LED selection function” automatically selects the LED for the largest contrast (S / N ratio) between the mark and base (non-mark area) to ensure optimal sensing. For more stable detection, the sensor makes selections according to the contrast and not according to the reflected light variation between the mark and base (non-mark area).
[The example on shown below deals with reflected light on packing film.
Great figures are indicated for the blue LED’s light amount ratio and, for even more stable sensing, the blue LED effectuates this mark sensing.]
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 achieve 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.
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 reflective light ratio. This function enables effective detection of films with patterns around the area of the mark.
