LX-101

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). 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.

Two detection modes can be selected to suit the application, 1) Mark mode [Ultra high-speed response] 2) Color mode [High precision 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 figure below is a graphic description of this process.

The 4-digit digital display enables easy verification of received light from marks and base (non-mark area). Also, the threshold value can be controlled numerically enabling setting indication easily. Displaying the direct code enables settings verification. This function is handy for remote maintenance. The sensor’s basic operations are represented by 6 indicators (MODE NAVI). The user can check what mode the sensor is presently in with a quick glance making the operation simple. The sensing status, displayed numerically, can be verified at a glance. Also, the sensor settings for each type of packing film can be digitally indicated.
