The Erhardt+Leimer Model OL 6335 Smart CCD Line Scan Camera (Material Number: 00868666, HS Code: 85258900), engineered and manufactured by Erhardt+Leimer GmbH in Augsburg, Germany, is a premier intelligent optical sensing instrument designed for high-speed continuous web surface flaw inspection and dimensional tracking.

The Autonomous "All-in-One" Optical Inspection Advantage:
Traditional line scan cameras act merely as image capture heads, requiring high-bandwidth frame grabbers and bulky industrial vision PCs to process pixel data. The Erhardt+Leimer OL 6335 integrates the complete evaluation electronics directly inside the camera housing:
- 192-bit parallel processing architecture.
- Multi-tier processing hardware combining a high-density FPGA, a dedicated Digital Signal Processor (DSP), and an embedded DIMM-PC.
- Autonomous execution of the complete vision pipeline: image acquisition, lighting compensation, defect segmentation, feature extraction, and real-time defect classification directly at the sensor head, transmitting ready-to-use defect coordinates and control triggers over Ethernet TCP/IP or industrial CAN-bus networks.

Model Number Breakdown & Configuration (OL 6335 / 00868666):
- OL 6335: High-resolution smart CCD line scan camera series within the E+L OL family, incorporating an integrated f = 35 mm focal length optical configuration.
- 00868666: Erhardt+Leimer proprietary factory material identification code.
- 4096 Pixels (4K): High-density CCD linear array delivering micron-level flaw detection across wide web converting formats.
- 10-Bit Dynamic Range: Delivers 1024 grayscale levels, providing superior contrast resolution to detect faint surface stains, creases, and subtle texture anomalies.
- Integrated f = 35 mm Optical Package: Factory-fitted high-precision optical lens with integrated motorized autofocus, automated CCD chip alignment, and continuous illumination drift self-calibration.
- Dual Open Communications: High-speed Ethernet TCP/IP interface for host SCADA / MES manufacturing execution integration and CAN-bus for direct synchronization with E+L web guiding and positioning actuators.

Key Engineering Features & Operational Advantages:
- Automated Optical Commissioning (Autofocus & Chip Alignment): Eliminates delicate manual focal adjustments. The internal motorized assembly automatically calibrates lens focus and sensor alignment based on working distance, while dynamic auto-calibration routines compensate for LED light source aging over thousands of operating hours.
- High-Speed Real-Time Defect Classification: Leveraging 192-bit parallel processing across its FPGA and DSP cores, the camera segments and classifies defects (such as holes, oil splashes, edge splits, inclusions, and misaligned yarns) at production speeds exceeding hundreds of meters per minute without latency.
- Heavy-Duty Industrial Metallurgy: Built with a rugged die-cast metal housing sealed against textile fly, industrial dust, and ambient humidity. Integrated thermal management stabilizes the CCD array, preventing temperature-induced dark current noise.

Target Industrial Sectors & Applications:
- Technical Textiles & Non-Wovens: In-line inspection of woven fabrics, knitted goods, and medical non-wovens; detecting broken threads, needle holes, oil stains, and continuous web width tracking.
- Lithium-Ion Battery Production: Surface defect inspection on continuous cathode/anode slurry coatings, blister detection, and microscopic pinhole detection on separator films.
- Paper, Corrugated Board & Printing: Identifying surface tears, specks, coating voids, and edge breaks on high-speed paper machines and roll slitter-rewinders.
- Optical Films, Plastics & Rubber Calendering: Quality verification for BOPP/PET barrier films, extrusion coatings, and tire cord rubberized sheets prior to curing.
