Reasons why we recommend Linx Laser FSL 20/50

High-quality marking on a variety of materials for complete traceability

The Linx FSL20 and FSL50 are designed to create permanent, high-quality marks on a wide range of materials, including metal, plastic, rubber and packaging films. With a fine spot size and improved beam quality, they ensure precision on both small components and larger surfaces, making them ideal for products where clear marking is essential for traceability. This flexibility is particularly valuable in industries such as pharmaceuticals, electronics, automotive and grocery, where both readability and durability of the mark play a major role.

Designed for easy and flexible integration into production

With a compact design and flexible laser head, the Linx FSL20 and FSL50 can be easily integrated into both moving and static production lines. The two beam orientation options – standard or with a 90° Beam Turning Unit – allow the laser to be adapted for marking in any direction. This enables marking even in tight spaces and difficult-to-reach installations. The compact marking head and air-cooled design mean that the unit can be placed where it is needed, without reliance on large water-cooled systems or factory air sources, providing a simple and quick installation with minimal impact on the production workflow.

Low maintenance and long life for reduced operating costs

The Linx FSL20 and FSL50 are designed for long-term operation with a laser source that has a lifespan of over 100 hours, minimizing the need for maintenance and downtime. The IP000 rating provides additional protection against dust and splash water, making these lasers reliable even in more challenging environments. Air cooling provides high energy efficiency and eliminates the problems of leaks and additional maintenance often associated with water-cooled lasers. LinxDraw software allows operators to easily create and customize messages, reducing setup and changeover time – all to maximize production time and reduce total operating costs.

Frequently Asked Questions (FAQ) about Linx Laser FSL 20/50

The FSL 20/50 is developed to create sharp and high-contrast marking on:

  • Metals (stainless steel, aluminum, brass, copper, titanium)
  • Coated and anodized metals
  • Plastic (ABS, polycarbonate, polyamide, PEEK)
  • Electronic components and circuit boards
  • Mechanical and medical components

It is perfect for permanent product labelling, traceability and brand profiling.

  • FSL 20 (20W) – Recommended for detailed marking on plastic and thinner metals.
  • FSL 50 (50W) – Offers faster engraving and deeper marking, ideal for tougher materials and high volume production.

The choice depends on materials, production speed and labelling requirements.

The machine uses LinxVision software, which offers:

  • Easy setup and adjustment via touchscreen.
  • Automatic generation of dates, batch numbers and QR codes.
  • Import of graphics, logos and barcodes.
  • Flexible integration with production lines and ERP systems.

The system is intuitive and requires minimal operator training.

Yes, the FSL 20/50 is developed for seamless integration into automated production environmentsIt has:

  • Flexible mounting options for optimal placement in the production line.
  • Ethernet and RS232 communication for connection to other systems.
  • PLC support and I/O control for integration with conveyor belts and robots.

It is perfect for high-volume production and industrial automation.

The fiber laser is almost maintenance-free, with:

  • Long lifespan (up to 100 hours of operation).
  • No use of ink or consumables.
  • Minimal cleaning – only the lens and protective glass need to be checked regularly.

This makes it a cost-effective and reliable solution.

The FSL series is used in several industries, including:

  • Electronics (printed circuit board marking, component ID)
  • Medical technology (labelling of surgical instruments and medical products)
  • The automotive industry (engraved serial number and chassis number)
  • The manufacturing industry (marking of tools, machine parts, plastic components)
