QB30 Stationary Scanner

Stationary Scanner QB30

This compact, stationary scanner (USB or RS-232C connection) quickly reads 1D and 2D codes. Its primary applications are on conveyor lines in manufacturing and warehousing. It is also serves applications in healthcare, pharma, events and entertainment, and retail settings.

Key Benefits

Small Footprint 

QB30 weighs less than 5.3 oz. Its compact body and wide-angle lens enable it to be installed in small spaces, close to its scanning targets. This is perfect for mounting inside kiosks or where space is limited.

Tough & Durable

Performs reliably in temperatures from -4 to 122 °F (-20 to 50 °C) with proven impact resistance (IP54).

Batch Scanning of Multiple Codes

QB30 can scan up to eight codes of two different types at once, significantly increasing productivity.

Fast and Trouble-Free Scanning

Scans codes up to 800 mm per second. Alerts user of confirmation and/or errors via LED (blue, green, red) and buzzer (three tones and volumes).

Convenient Magic Key

A Magic Key provides simple control for “Scanning On/Off.” On the USB model it also enables interface switching.

Lighten the Host Load

You can edit data with “ADF Script,” a simple program language for data extraction, addition, sorting and other common editing functions.
