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).
