Konica KM512LNX Printhead

The Konica KM512LNX printhead is a high-performance industrial inkjet printhead featuring 512 nozzles spaced at 360 nozzles per inch. It is a shear mode, piezo electric, on-demand printhead. The one referred to as KM512LNX typically has a droplet size of 35 picoliters and supports solvent, oil-based, and UV inks, with a native resolution of 360 dpi. It is designed with a "wing" structure for precise alignment and easy combination in page-width printhead units for high-speed single-pass printing.

The printhead is compatible with various large format printers such as Agfa Anapurna Mv and Mw and others. Variants in the KM512 series come with different drop volumes (14, 35, and 42 picoliters). This printhead is notable for its robust performance, wide ink compatibility, and suitability for industrial printing with solvent and UV inks.​
