The LS-REGSENSOR utilizes a white LED light source that is optimized to detect printed registration marks on translucent, transparent, and many metalized films and paper. This sensor is particularly useful on form, fill, and seal machines. Note that most packaging materials (except foil) are translucent! Many of the translucent packaging materials that we have tested allow light to penetrate either the backing material or the registration mark. Because this sensor operates in the opacity sensing mode, the color of the registration mark simply doesn’t matter! Note: Marks as small as 1/16” wide by 1/4” long can be detected, dependent upon web opacity (contrast) and velocity.
The LS-REGSENSOR operates on 10 to 30 VDC and is pulse modulated to prevent any problems with ambient light. Its design incorporates a white LED light source directing a beam of light across the gap to the receiving lens of a photoelectric detector. In operation, the moving web of packaging material passes through the gap/slot. This sensor can detect registration marks in a wide variety of applications, as long as the size of the mark and velocity meets the capability of the sensor. When the intensity of the light beam transmitted through the web of material is altered by the presence of printed registration mark, the LS-REGSENSOR will switch its output accordingly. Note: For “Metalized” film that does not produce the desired response, we recommend sensing with a reflective mode sensor.
