EC: DataMan 300 Series ID Readers

Machine and Embedded Control - Machine vision, barcode readers: The DataMan 300 is a fixed-mount, image-based, industrial ID reader designed to handle the most difficult ID code-reading applications including barcodes, 2-D matrix and difficult-to-read DPM (Direct Part Mark) codes. This is a Control Engineering 2013 Engineers' Choice finalist.


The DataMan 300 is a fixed-mount, image-based, industrial ID reader designed to handle the most difficult ID code-reading applications including barcodes, 2-D matrix and difficult-to-read DPM (Direct Part Mark) codes. This is a Control Engineering 2013 Engineers' Choice finalist.The new DataMan 300 readers offer dramatically increased 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. These code-reading algorithms take the DataMan 300 a quantum leap beyond the current best-in-class technology. 1DMax+ with patent-pending Hotbars technology is a breakthrough in image-based barcode reading.

Invented by Cognex’s 31-year veteran Bill Silver, Hotbars uses texture to locate barcodes at any orientation, and then extracts 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 DataMan 300 readers unprecedented performance. The 2-DMax+ algorithm is also 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. Because 2-D DPM code reading is inherently difficult due to the normal manufacturing processes that parts undergo, the DataMan 300 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. In another leap, the DataMan 300 series offers the flexibility of integrated and controllable modular lighting and optics. The user can purchase just one model and choose the appropriate lens for their required working distance and field of view. The controllable, field changeable lighting modules allow the user to create the best possible lighting for their part, ensuring optimal read rates. Cognex Corp.
