Barcode Scanners
FM431 Fixed Mount
Automatic Exposure Control (AEC)
The sensor in the NLS-FM431 automatically adjusts the supplementary lighting duration based on the light reflected off barcode.
Dual Aimer Systems
The FM431 contains a red laser aimer that produces a crosshair aiming pattern. It is clear and bright even in bright sunlight, ensuring first time accurate aim. Besides, the scanner provides a green LED aimer.
Improved Motion Tolerance
NLS-FM431 can capture and decode the barcode in motion up to 3.5m/s.
UIMG ® Technology
Armed with Newland’s seven-generation of UIMG ® technology, the scan engine can swiftly and effortlessly decode even poor quality barcodes (e.g., low contrast, laminated, damaged, torn, warped or wrinkled).
