Linx FSL20 & FSL50

Linx FSL20 & FSL50

Fibre laser technology for permanent coding on a wide range of materials

Permanently mark on a wide range of materials, including metal, rubber, plastic, and packaging foils. Very fine spot size creates excellent quality codes and makes Linx Fibre lasers ideal for marking very small components, or large amounts of information onto small areas. Text, machine readable codes, graphics and logos are all marked with extreme clarity for traceability; ideal for pharmaceutical, medical devices, automotive and electronics industries, as well as FMCG packaging.

Key benefits

  • Laser tube life of over 100,000 hours - less downtime
  • Fine spot size for high quality codes
  • Two beam orientation options allows coding in any direction
  • Choice of 4 lenses for codes tailored to your requirements
  • Compact marking head for easy integration into moving and static lines
  • Internal air cooling system for increased efficiency and less maintenance
  • Quick message creation reduces time spent on setup and changeovers
  • Extremely efficient use of the laser with no compromise on code quality or speed
