Product Identity

The Datalogic QW2120-BKK1S is a new corded handheld barcode scanner supplied as a USB kit with a collapsible stand. It uses a 1D linear imager engine with LED illumination to read all standard linear codes and GS1 DataBar variants. The unit draws 340 mA while operating and 190 mA in standby from a 5 VDC USB supply. It targets retail, light manufacturing, document processing and finance users who need reliable single-plane scanning at a fixed workstation.

Upgrade Context

This kit replaces older laser or CCD scanners that struggle with truncated or low-contrast 1D symbols. The 400 reads-per-second linear imager handles 4 mil resolution and maintains a 25 percent minimum print contrast ratio. The jump is worth it when bar codes are long, wide or poorly printed, such as utility bills or electronic-part labels, because the extended scanning line captures them without increasing distance. Buyers who need 2D matrix codes or wireless freedom should look elsewhere.

Installation Notes

Plug the included USB cable into a host port; the scanner enumerates as a standard HID device without extra drivers. The lightweight stand folds flat to serve as a holder and its tiltable head adjusts for comfortable presentation angles. Common issues include insufficient USB current on unpowered hubs, which can cause intermittent reads, and glare on highly reflective surfaces that exceeds the 25 percent contrast threshold. Ensure the host port supplies a steady 5 VDC ± 5%.

Questions about this item

What USB cable length does the QW2120-BKK1S kit need to reach my PC?

The kit includes a USB cable that draws 5 VDC ± 5% from the host port; operating current is 340 mA and standby current is 190 mA.

Which step is often missed when installing the QW2120-BKK1S with its stand?

The stand head tilts; set the desired angle before locking it so the 1D linear imager stays aligned with the barcode.

When will the scan window on the QW2120-BKK1S need cleaning?

Clean the window when the LED light source shows reduced contrast on 4 mil codes; the engine reads at 400 reads/sec when the window is clear.
