Honeywell 3820

The 3820 cordless linear imager is ideal for retail and light industrial scanning applications where freedom of movement is essential. It combines high-performance linear barcode scanning with a read range out to 61 cm (24 in) and Bluetooth® wireless connectivity for productivity on the go.

The 3820 wireless linear-imaging scanner combines exclusive Adaptus™ Imaging Technology 5.0 with Bluetooth® wireless connectivity to provide performance and durability for retail and commercial wireless barcode reading.

If your team needs to be mobile to read barcodes, cables become a limiting factor. They cause inefficiencies or safety and ergonomic concerns. And cable length often limits working range. That can lead workers to move an object to the reader when it can’t be taken to the object. A time-consuming process.

That’s not an issue with the 3820 linear-imaging scanner.

The 3820 scanner equips your team with wireless barcode reading so they can move freely and scan barcodes quickly, safely, and ergonomically. With a 10 m (33 ft) working range and 61 cm (24 in) read-range, the 3820 scanner give you the right combination of performance and features to get the job done.

Having the right performance is only part of the solution; staying in service is just as important. The 3820 also features class-leading durability. We designed it to survive in real world mobile applications.

The 3820 scanner reflects Honeywell’s commitment to developing rugged products. With no moving parts and a tough housing design, the 3820 will easily provide years of service in retail and commercial environments, creating a favorable total cost of ownership.
