Datalogic offers a wide variety of barcode scanners designed with varying optical reading ranges depending on the specific model and intended industrial application. While standard retail presentation and handheld desktop scanners typically operate effectively at close quarters ranging from a few centimeters up to two feet, specialized industrial long-range area imagers and warehouse data-collection terminals are engineered with advanced autofocus optics. These heavy-duty devices can successfully read standard barcodes, high-density matrix codes, and retro-reflective warehouse rack labels from distances stretching multiple meters away, enabling efficient operation in high bay storage facilities.
