Cognex Dataman: Barcode Quantum Leap
Industrial ID reader.
Natick, MA — Cognex Corporation has introduced its most advanced fixed-mount industrial ID reader — the DataMan® 300. The reader is designed to handle the most difficult ID code-reading applications on even the highest speed lines. These new readers dramatically increase barcode read rates and speed with a new 1DMax+ algorithm, which incorporates groundbreaking new "Hotbars" technology.

For 2-D matrix and difficult-to-read DPM (Direct Part Mark) codes, reading performance has also been significantly improved from a major upgrade of 2DMax to the 2DMax algorithm. With the DataMan 300, setup and deployment is even easier than before, with modular, controllable lighting options and a unique intelligent tuning system.

DataMan 300 series offers two models. The DataMan 300 provides standard resolution of 800x600 pixels and the DataMan 302 is the high-resolution model at 1280x1024 pixels. The DataMan 302 is ideal for reading very small DPM codes on small components to ensure full part traceability.

Strong-performing code-reading algorithms have been advanced, taking a quantum leap beyond the current best-in-class technology. According to the company, 1DMax+ with patent-pending Hotbars technology is a breakthrough in image-based barcode reading, using texture to locate barcodes at any orientation, and then extracting high-resolution 1-D signals for decoding. With a solid mathematical foundation and meticulous assembly language programming, Hotbars combines superior signal fidelity with lightning speed, giving the next generation of Cognex DataMan readers extraordinary performance. The 2-DMax+ algorithm also is an upgrade from existing 2DMax technology, offering tremendous enhancements in handling damaged codes at high line rates and poorly marked or extremely damaged codes.

Both algorithms allow for the highest read rates possible. In another leap, the DataMan 300 series offers the flexibility of integrated and controllable modular lighting and optics. Users can purchase just one model and choose the appropriate lens for the required working distance and field of view. The controllable, field-changeable lighting modules allow users to create the best possible lighting for their part, ensuring optimal read rates. Because 2-D DPM code reading is inherently difficult due to the normal manufacturing processes that parts undergo, the system adds a new tuning feature to help form the best possible image of each part. This intelligent tuning technology automates the settings of the integrated lighting to find the optimal light setup for the part, making the DataMan 300 the most advanced DPM reader on the market.
