The Matrix 300N™ is a ultra-compact image based bar code reader purpose-built for superior performance on high speed and Direct Part Marking (DPM) applications. With a high resolution sensor and ultra-fast image acquisition at 1.3 megapixels/60 frames per second, Matrix 300N™ is the next-generation, compact imager in the Matrix family. The optical system incorporates a liquid lens module for electronic focus control. As result the reader offers automatic focus adjustment without the addition of moving parts. The integrated illuminator is embedded over the entire front surface of the reader. This innovative design allows for bright and uniform illumination of the bar code. The lighting design uses both bright field and dark field patterns, resulting in optimal illumination on normal, etched, reflective or textured surfaces. The Matrix 300N™ is the most cost effective solution for bar code imagers, providing onboard PROFINET-IO and ETHERNET/IP and eliminating external communication boxes or converters. The Matrix 300N™ interfaces directly with a PROFINET or ETHERNET/IP enabled PLCs, reducing the complexity and cost of solutions.
