di-soric fork light barriers offer fast, precise detection of small objects. The OGU platform features a dual operating concept — IO-Link with four selectable sensor modes or direct manual potentiometer adjustment — all in the same compact housing. Fork widths range from 5 mm to 251 mm. The family includes the standard OGU series in red- and infrared-light variants, the OGU Stainless Steel series for hygiene-critical environments, the OGUP dirt-resistant series for maximum power reserve in oily or dusty areas, and the OGUL Laser series for detection of features as fine as 0.03 mm.
