Scanner · Kiosk · Compact 1D/2D Imager · Long Reading Distance · IP54 · USB Cable · Black
The NLS-FM431 kiosk barcode scanner delivers fast, long-range scanning for high-throughput self-service and warehouse environments. Designed for fixed-mount installation, it reads printed and mobile 1D and 2D barcodes with reliable performance across damaged, low-contrast, and difficult-to-read labels. Its extended scanning range and enhanced motion tolerance make it well-suited for parcel lockers, warehouse pickup stations, inventory kiosks, bulk retail environments, and logistics workflows where larger or harder-to-reach barcodes are common. Compact and easy to deploy, the FM431 helps support fast, reliable barcode scanning across demanding kiosk and self-service applications.
