QB30 Series

QB30 Series

The ultimate fixed type 2D Code Scanner

The QB30 is available as a wide-field model with small footprint or as a standard-range model which allows scanning from a distant position, depending on the application. It can be operated between -20 – 50°C and its safety functions block the intrusion of dirt and water drop.

    *1: Value at the scanning reference position

    *2: This is the reference value when a QR code with a cell size of 0.33 mm/Ver5 is scanned at the scanning reference position
    with the use of an exterior trigger, and is subject to change according to actual ambient conditions.

    *3: When the RS-232C model is connected to an external device by using
    the D-sub9PIN, a D15-to-D9S conversion cable and an AC adopter are required.
