High-Power, Environmentally Resistant YAG Laser Marker
KEYENCE has used its long-established, reliable technology to create an advanced laser marker that satisfies the levels of strength and durability required in harsh production environments. The MD-H9800 incorporates an advanced dust-proof structure with a high-powered laser.
Worldwide Specifications - Conforms to FDA, CE Marking, and GB Standards
For the first time in the industry, the MD-H Series has satisfied worldwide specifications conforming to the standards of the U.S.A. (FDA), Europe (CE Marking), and China (GB Laser Safety Standard). Reliable operation is ensured in overseas locations based in the US, Europe, and China.

Air-Cooled, Double Dust-Proof Structure Reduces Operating Costs
The MD-H does not require a water cooling system, cooling water, ion-exchange resin, filters or other consumable supplies required by conventional YAG laser markers. The air cooling system provides reduced running costs, less maintenance and a smaller installation space.
Double Dust-Proof Sealing Eliminates Environmental Contamination
The housing of the marking head is completely sealed (1st dust-proof structure) and the inner laser light path is completely isolated (2nd dust-proof structure). In addition to the double dust-proof design, the newly employed structure of the separated cooling area completely blocks dust and oil mist, maintaining stable marking performance.
Dust, dirt, and oil mist… tough construction for reliable,trouble-free marking performance under harsh conditions. The entire housing of the marking head is completely sealed (1st dust-proof structure) and the laser light path inside the marker unit is completely isolated (2nd dust-proof structure). The double dust-proof structure with the 1st and 2nd dust-proof walls completely blocks dust and oil mist, maintaining stable marking performance.
The entire path of the laser beam, from the laser oscillator in the marker unit to the scanner area, is housed in a metal block to achieve complete isolation. Extreme cleanliness is maintained by employing a completely seamless all-in-one structure without exposing the laser oscillator, scanner, lens and other important optical components to impure substances.
External air that enters the cooling chamber cannot contaminate the laser oscillator or the scanning area with dust, dirt or oil mist. The innovative idea of completely separating these chambers provides a perfect air cooling system that is unmatched by conventional YAG systems.
Industry's Deepest Focal Depth
By optimizing long established optical marking technologies, KEYENCE has succeeded in creating a YAG laser marker with a large focal depth of ±7mm. Even when the target distance varies such as with irregular or curved surfaces, clear marks can be produced. The MD-H has the best focal depth in the industry for an air cooled YAG laser marker
No Water Cooling Equipment or Supplies Required
The completely air-cooled system eliminates the need for water cooling equipment that is normally essential for conventional YAG laser markers. Since no water is used to cool the laser oscillator, there is no need to periodically replace the ion exchange resin, filter, or pure water. This system has reduced the running costs and man-hours for maintenance services. In addition, installation space for the equipment has been reduced. As a result, production efficiency can be improved\\
Characters to be Marked Are Displayed on the Workpiece Surface
The guide laser scans a red laser beam at high speed to display the characters and area of marking on the actual work piece. This function ensures accurate positioning even on small workpieces or targets with a complicated profile. In addition, the marking area and ruled-line guide laser will help confirm the maximum marking area or compensate for the angle.
MD-H9800 Accepts CAD Data Directly
Most conventional markers cannot accept CAD data because of a difference in DXF file version or format. With the MD-H Series, data conversion is no longer necessary. Graphics stored as CAD data can now be captured directly using KEYENCE Marking Builder software and then printed with the MD-H Series.
