Product description
The VB34 is the high-performance laser scanner in the VISOLUX family of barcode
readers for industrial applications. With its completely new hardware and software
platform, it offers innovative and modular solutions regarding performance,
communication and maintenance.
Easy installation and operation as well as high flexibility were the most important
features during the development of the VB34. Together with the Step-a-Head™
technology, for which a patent has been applied, the innovative mechanics makes it
possible to turn the read head and the decoder base assembly independently of each
other. Step-a-Head™ makes it possible to always install the VB34 in the ideal position
by changing the position of the base assembly while the read head with the laser
maintains its optimum position. This minimises the space requirements and simplifies
the installation.
Another innovation of the VB34 is the linear motor, which can be used to control the
reading position of the scanner via software. This dynamic system with the name
Flash™ is able to assume any reading position from the minimum position to the
maximum position in less than 10 ms. In typical applications with a reading distance
of less than 1 m, the reading position is reached in 4 ms.
Thanks to a new generation of decoders with StrongARM CPU and ACR technology
(ACR™ 3 reconstruction), the VB34 reads all current barcodes, even under
demanding ambient conditions.
The reader is also available in a version with an integrated, software-programmable
oscillating mirror.
Another focus in the system design was the communication capacity of the readers.
As interfaces, Lonworks, Profibus, DeviceNet and Ethernet were each integrated into
a separate version of the decoder base assembly.
Some of the significant features of the VB34 are:
• Read rate of up to 1200 read processes/second
• 2 serial interfaces
• Reading all current codes
• Operating voltage of 15 to 30 V DC
• All electrical connections pluggable
• Fast Lonworks interface for master/slave configurations
• Supports Profibus, DeviceNet and Ethernet
• 5 operating modes for an optimum adjustment to different application requirements
• Light source: laser diode with a wave length of 630 to 680 nm
• IP64-protected housing (for Ethernet models not yet available)
Auto-ID applications are traditionally used in the area of production. With increasing
marketability, standard solutions and a dynamic competition develop. The VB3x
family with the model VB33 also has its roots in production applications. The VB34
opens up new areas of application such as, for example, transport and logistics
applications, in which the practical advantages of the new technologies come to the
fore.
