20 W Fiber Laser Coder
Compact on-the-fly fiber laser for date, lot and 2D codes on metal and plastic packs.
Built around your product
The FL-20 is the entry point to consumable-free coding. Its air-cooled 20 W source and short scan head fit into tight spaces on filling and packing lines, and it marks cans, closures, blister foil and moulded parts without stopping the conveyor.
A ytterbium-doped fiber source generates the beam, a pair of galvanometer mirrors steers it across the marking field, and an F-theta lens keeps the spot in focus over the whole area. On moving lines an encoder tracks product speed so the code stays undistorted. MOPA sources add adjustable pulse width, which is what makes black marking on anodised aluminium and colour marking on stainless steel possible.
Key features
- Air-cooled source with no routine consumables
- 10-inch touchscreen with drag-and-drop message editor
- Encoder tracking for stop-start and variable-speed lines
- Prints text, logos, GS1 DataMatrix and QR codes
Process sequence
Detect
A photo-eye or PLC signal tells the controller a part has arrived.
Track
The encoder reports line speed so the scan head can follow the moving surface.
Mark
Galvo mirrors steer the pulsed beam to draw text, logos, 1D and 2D codes.
Extract
Fume extraction removes particulates at the marking point.
Verify
An optional camera reads the code back and rejects any failure.
