With its compact body and wide-angle lens, QB30 can be installed in a small space without needing to be a certain distance from the scanned object. It can reduce installation space when mounted on a kiosk terminal, allowing users to install it anywhere they wish.
*It is recommended to use a low-reflection coating plate in case you wish to install a plate on the scanning side.

Scanning performance
Two models available, depending on the application
[QB30] Wide-field model with small footprint

[QB31] Standard-range model allows scanning from a distant position
With its deeper scanning field, QB31 can scan objects distant from it. It is perfect for plant production lines, thereby contributing to improved site productivity

Full functions
Easy setup function adopted
“QB setting,” which is a software application enabling users to easily set up scanning conditions and data formats according to the scanned objects, is provided free. It simplifies the troublesome setup process, reducing the user’s burden at the time of introduction.
Data collation and edit functions adopted
The scanner features a function for collating registered master data (up to 50 items) with scanned code data, helping to build a system that checks for foreign articles prevents wrong labels from being affixed. Furthermore, since the scanner is compatible with the simplified programming language “ADF Script,” data editing, including sorting, extraction and conversion, is possible, reducing the burden involved in development of higher level systems.
Internal environment performance
Safety function which blocks the intrusion of dirt and water drop
Materialized IP54, the protection rating of IEC. Shut out ingress of dust at the production line or rainwater at a semi-outdoor. It can be installed safely

Operating temperature
-20–50°C
It supports operating temperature of -20–50°C and can be installed safely at a semi-outdoor entrance gate.
