Spectra SL-128 AA Printhead (80 pl, S-Class)

The Spectra SL-128 AA is a lightweight, compact, piezoelectric drop-on-demand printhead belonging to the industry-renowned S-Class line. As the heavy-drop representative of this series, the “SL” model features a robust 80 pL calibrated droplet volume. It is specifically engineered for demanding production environments requiring high opacity, rapid color deposition, and reliable handling of high-viscosity pigmented fluids, such as industrial white inks, varnishes, and heavy outdoor solvent inks.

Core Features & Advantages

• Superior Opacity & Coating Thickness: The substantial 80 pL droplet size quickly builds high-density solid ink layers, providing unmatched color saturation and excellent undercoating capabilities—making it an ideal choice for white ink channels, varnish applications, and wide-format graphics.
• High-Speed Large-Drop Jetting: While maintaining a large 80 pL output, it still supports an impressive firing frequency of up to 30 kHz, significantly boosting throughput for single-pass production lines or heavy-duty scanning systems.
• Compact Modular Stitching: Its slim profile and ultra-lightweight design (approx. 60g) make it highly convenient for system integrators to configure tightly staggered or overlapping multi-head matrices to easily build high-resolution arrays.
• Heavy-Duty Industrial Lifespan: Built with a robust stainless steel housing and chemically inert internal fluid paths, it easily withstands highly aggressive and abrasive industrial inks, ensuring maximum jetting stability during 24/7 continuous operation.
