Barcode scanner



Ideal for light industrial linear scanning applications where freedom of movement is essential, the 3820 combines the performance of Adaptus® Imaging with Bluetooth™ wireless connectivity.


High-Performance Linear Scanning: Fast performance and broad read range for ease of use in a variety of linear applications.

Effective Wireless Connectivity: Enables movement up to 33 feet (10m) from the base while its Adaptive Frequency Hopping (AFH) feature eliminates interference with other wireless systems.

Extended Battery Life for Dependable Use: Field-replaceable lithium-ion battery enables up to 57,000 reads per full charge.

Light-Industrial Durability: Built for reliability in light-industrial environments including retail, healthcare and manufacturing.

Multi-Bay Battery Charger: Fully charges up to four lithium-ion batteries in approximately 4.5 hours, maximizing uptime in any application.
