A line of stationary 1D/2D code readers from the Siemens Industry Automation Division is characterized by its high reading reliability and speed as well as by diverse communication and connection possibilities. The rugged Simatic MV440 code-reading systems, which feature high protection rating IP67, read data matrix codes such as direct part marks (DPMs) under difficult ambient conditions in industrial environments.
The readers have many lighting options so they can be adapted to many different applications. Integrated lighting can be used when objects are within 80 centimeters of the reader. External lighting extends that distance to as much as three meters. Systems can be configured with and without verification, and resolution can be set at either 640×480,1024×768 or 1600×1200 pixels. The Simatic MV440 reads up to 80 codes per second, reliably detecting up to fourteen types of code that have previously been stored in the device.
Its multi-code reading feature lets the system decode up to 50 codes every time an image is recorded. This is advantageous for bulk-reading of several objects, such as when objects are stacked one on top of the other.
An auto trigger feature lets the code reader record images at maximum speed while simultaneously evaluating them. The reading device looks for codes in a sequence of images of any length, without the need for any external triggering signals. That’s particularly suitable for slow-moving objects and in applications where precise triggering by a light barrier is difficult to implement.
The readers can be parameterized and commissioned via a built-in web server. When the user employs a PC or a programming device with Internet Explorer installed, no additional software is needed.
For most applications, the parameters are preset automatically. The web-based user interface provides comprehensive operator control and visualization functions, even in evaluation mode. Moreover, human machine interface (HMIs) make it possible to display the image information.
Typical uses are product tracing, process control and checking the quality of marking in a variety of applications in the automotive, packaging, pharmaceutical, tobacco, cosmetics, electronics and food & beverages industries.
