Konica Minolta KM512 LH 42PL Industrial Inkjet Printhead – New in Original Factory Packaging

The Konica Minolta KM512 LH is a robust, shear-mode, piezo on-demand industrial printhead designed for high-speed, high-reliability printing with oil-based, solvent, and UV-curable inks. The “LH” variant includes an integrated heater (up to 55 °C), making it especially suitable for high-viscosity UV inks that require temperature control to maintain optimal viscosity at the nozzle.

With 512 nozzles arranged in two staggered lines (256 × 2) and a native resolution of 360 dpi, the KM512 LH delivers consistent drop placement and strong coverage for wide-format graphics, industrial marking, packaging, and custom inkjet systems. Its compact, winged mechanical design simplifies precise multi-head alignment in production printers.

This listing is for one new, factory-sealed KM512 LH printhead in original Konica Minolta packaging.
