The USB-connected Datalogic GD4220-BKK1 is a corded, handheld 1D imager that delivers a scan rate of 400 scan/s, covering all standard 1D codes including GS1 DataBar linear symbologies through automatic discrimination. Motionix motion-sensing technology detects operator movement to switch the scanner into ready-to-read mode without manual intervention, while a soft line viewfinder assists precise code targeting in multi-label environments. Datalogic's patented Green Spot technology projects good-read feedback directly onto the code, complemented by the 3GL three-green-lights indicator and an audible beeper — features that suit dim-light or high-noise workstations in retail, pharmacy, light industrial and document-handling settings. The black handheld chassis weighs 5.75 oz, carries an IP52 water and particulate sealing rating, and withstands drops to 1.8 m. Disinfectant-Ready enclosures support daily cleaning with harsh solutions, making the GD4220-BKK1 suitable for healthcare and other hygiene-sensitive deployments.
