Fiber laser marker LF101/LF201

Versatile fiber laser markers

ALLTEC LF101 and LF201 are compact, versatile and highly reliable for industrial direct part marking applications on a variety of metal, plastic and various other hard-to-mark materials in the electronics, tools/metal and automotive as well as automobile supplies industries.

The 10 and 20 Watt pulsed fibre laser marking systems quickly apply complex variable data (ID matrix/bar codes, logos, characters, [serial] numbers, individual data, etc.) on both moving and static products. Additional advantages include low maintenance and ease of integration with the system’s dovetail joint mounting interface and a multilingual user interface.

Whether through engraving, high contrast color change, material removal or annealing – the solid-state laser marking systems LF101 and LF201 deliver high resolution and brilliant marking quality.
