A fiber laser marker utilizes a fiber optic cable that has been doped with Yb (Ytterbium) as a laser generating medium. The fiber laser doesn't require an amplifier and offers higher performance compared to solid-state lasers, making it possible to decrease the size of the marker. A high light conversion ratio allows for decreased power consumption compared to conventional laser markers.

The MD-F Series combines a high-power 30 W output and naturally-cooled fanless marking unit by maximizing the cooling effect using original technology developed by Keyence. This brings dramatic improvement in marking time and quality in most applications.

The MD-F Series has a built-in laser power monitor in what is reportedly the world's smallest marking unit. Thus, external devices are no longer necessary since it is now possible to do easy and accurate measurement of laser outputs without making contact with the equipment. This makes on-site preventive maintenance easy for any operator and will ensure that each mark is made with the same quality and consistency, regardless of the age of the marking head.

Precise 3D marking is possible on complex shapes with 3-axis marking controlled by the Z-axis scanner. With the 3D configuration software, marking on any target surface is easily programmed.

The MD-F series can play an important role in every industry, including the automotive, precision part manufacturing, and medical industries. Precise 2D codes can be marked on automotive parts at high speed, which greatly contributes to improved productivity for management of manufacturing history and process controls. For precision metal components, it can produce easy to read, black markings. The MD-F series can generate highly-visible black markings while minimizing surface damage. In medical industry with 2D codes on medical equipment, reliable distinct marks can be provided not only for the manufacturing history, but also for tracking equipment through the sterilization process, usage history, storage and maintenance.
