New Original Keyence SR-X300W AI Barcode & DPM Code Reader (PLC Industrial Communication Supported)
1. Product Overview
The SR-X300W is a fixed-mount wide-range AI-powered industrial code reader from Keyence SR-X series, engineered for stable decoding of 1D barcodes, standard 2D QR/Data Matrix codes, and hard-to-read DPM (Direct Part Marking) codes etched, peened or stamped on metal, plastic, ceramic and semiconductor components. Integrated with high-resolution CMOS image sensor and multi-angle adjustable LED lighting array, this model delivers ultra-wide working distance coverage ranging from 50 mm to 1000 mm, supporting code detection on fast-moving conveyor workpieces and large-format product surfaces.
Equipped with built-in industrial Ethernet communication ports, the SR-X300W natively supports mainstream PLC industrial bus protocols including PROFINET, EtherNet/IP, MC Protocol and OMRON PLC Link, enabling seamless two-way data interaction with all brands of industrial PLC, touch HMI, industrial PC and automation controllers without extra signal converters. The fully sealed IP67 rugged housing resists cutting fluid splashes, metal dust, workshop vibration and temperature fluctuations, making it ideal for automotive assembly, lithium battery production, precision machinery processing, electronics SMT lines and full-process product traceability systems. As a brand-new original factory unit, it adopts self-developed AI decoding filter algorithm to eliminate interference from scratches, smudges, reflection and uneven marking surfaces, drastically improving first-pass read rate in harsh industrial production environments.
2. Main Functions
- Full-range DPM & label code decoding: Identifies dot peen, laser engraving, ink printing, embossed 2D Data Matrix, QR and all standard 1D barcode symbologies.
- Native multi-PLC industrial bus communication: Direct data exchange with Mitsubishi, Omron, Siemens and Keyence KV series PLC via PROFINET, EtherNet/IP and MC protocol.
- Ultra-wide depth-of-field detection: Covers 50 mm to 1000 mm reading distance to adapt variable workpiece placement heights on assembly lines.
- AI intelligent noise filtering algorithm: Automatically suppresses image noise caused by scratches, reflection, oil stains and incomplete marking for high reading success rate.
- Multi-angle adaptive LED illumination: Independent adjustable red/white LED groups eliminate specular reflection on polished metal and shadow interference on concave surfaces.
- Real-time digital I/O trigger control: 2 bidirectional input channels and multiple output signals for synchronization with conveyor motors, sorting actuators and PLC logic programs.
- PoE power supply compatibility: Supports IEEE802.3af PoE Class 3 power input to simplify wiring layout inside control cabinets.
- Multi-code simultaneous capture: Recognizes up to dozens of codes within single image frame and uploads all decoded data to PLC in one transmission cycle.
- Remote parameter configuration & firmware upgrade: Ethernet-based remote debugging without physical USB connection to reduce on-site maintenance downtime.
- Visual multi-status feedback: Built-in LED indicator and digital display to show reading success, communication fault, trigger standby and abnormal decoding status.
