OEM Megapixels Metal Surface Barcode Scan 1D 2D QR Barcode Scanner Engine Module with Metal Housing for Industrial Application
DPM Barcode Scanning for Factory Traceability
HW-1220E Scan Engine with Anti-Reflection Lighting - Solve DPM code reading on metal and plastic surfaces with advanced tri-color LED technology, 120FPS CMOS sensor, and laser aiming for MES traceability, incoming inspection, and production tracking.
Solving Reflective Surface Challenges
Reading DPM codes on reflective metal and plastic surfaces presents significant challenges in factory barcode scanning. Specular reflection can wash out contrast, standard illumination often fails, and traceability systems break down. The HW-1220E barcode scan engine is specifically engineered to overcome these obstacles.
Tri-Color Adaptive Illumination Technology
When white LED illumination hits polished or machined metal surfaces, glare can completely obscure laser-etched DPM codes. The HW-1220E addresses this with an intelligent tri-color illumination sequence:
- White LED: Initial attempt for general surfaces
- Red LED: Automatic switch to reduce glare on reflective substrates
- Blue LED: Final fallback for the most challenging low-contrast marks
This staged approach ensures the engine doesn't rely on a single lighting condition, adapting in real-time to improve read rates on metal, plastic, and curved parts that typically defeat conventional industrial scanners.
High-Performance Hardware Specifications
- 1280×800 global shutter CMOS at 120FPS - captures fast-moving codes without rolling-shutter distortion
- Ingenic 1.2GHz 1660-series processor - handles real-time decoding and MES data integration
- Laser aiming beam - ensures accurate targeting on small, dense, or low-contrast marks
- Metal-enclosed housing - conducts heat away from internal components for stable long-shift operation
Factory Traceability Applications
This scan engine supports comprehensive end-to-end traceability from raw material to shipment:
| Production Stage |
Scanning Task |
| Incoming inspection |
Verify raw material DPM codes |
| Material picking |
Track components to work orders |
| MES entry |
Capture code data at each operation |
| Final inspection |
Confirm finished product identity |
| Warehousing & shipping |
Record outbound traceability data |
Deployment Options
Handheld Integration: Embedded into handheld terminals or PDA scanners for mobile DPM reading on fixtures, tooling, and large parts.
Fixed-Position Scanning: Mounted at workstations where operators place parts in front of the scan window for automatic barcode capture. This supports inline traceability and high-volume production line scanning without manual trigger operations.
Manufacturing Benefits
Factory traceability systems depend on reliable DPM barcode reading at every production step. The HW-1220E's combination of tri-color adaptive illumination, high-speed CMOS imaging, and laser aiming makes it an ideal scan engine choice for manufacturers requiring metal DPM code reading, plastic surface decoding, and MES-connected traceability in a single compact module.
