Datalogic - QuickScan Lite QW2100

An entry level product created specifically for reading long and truncated barcodes which is common in some areas of the world. It is perfect for use in retail, light manufacturing, document processing and banking environments.

Snappy Performance and Comfortable to Use

The QW2100 imager is small, lightweight and its ergonomic design is comfortable to use during daily operations. It offers snappy reading performance on most 1D barcodes and features a wide scanning angle with an extended scanning line which is perfect for capturing longer and wider bar codes typically found on utility bills and used by manufacturers of electronic parts. The scanning line is thinner and brighter, allowing users to scan at wide angles without having to increase the scanning distance.

Green Spot Good Read Feedback

The QW2100 imager features Datalogic’s exclusively patented ‘Green Spot’ technology for good-read feedback directly on the code. When the reader is in Stand Mode, the Green Spot remains on to show the operator where to position the code for quick and intuitive reading.

Adjustable Stand for Any Angle

A specially designed stand has been created for the QW2100 imager which is light in weight, collapsible to use as a holder and can also be titled to various angles.

Connectivity Options

The QW2100 imager is available with two interface options: USB or Keyboard Wedge and Serial (RS-232) and includes various packaging options so that it can be ordered as a scanner only or as a kit equipped with a scanner, cable and stand to facilitate hands-free barcode scanning. The Datalogic Aladdin configuration software provides user-friendly features that simplify the start-up procedure, even for inexperienced users.
