Spectra SL-128 AA Industrial Large-Drop Piezo Printhead

The Spectra SL-128 AA is a lightweight, compact, piezoelectric drop-on-demand printhead belonging to the industry-renowned S-Class line

Product Overview

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.

Key Technical Specifications

  • Active Nozzles: 128 independent channels arranged in a compact single-line array
  • Nominal Drop Size: 80 pL (high volume for superior physical coverage)
  • Maximum Firing Frequency: 30 kHz (highly efficient output for a large-drop architecture)
  • Nozzle Spacing: 508 microns (physical resolution of 50 dpi for a single head)
  • Operating Temperature: Supports up to 90°C (with an integrated precision heating and temperature control system)
  • Fluid Compatibility: Fully compatible with UV-curable, strong/eco-solvent inks, and industrial functional fluids

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.

Printer Compatibility

High-Speed Variable Data Inkjet Systems: Heavy-duty industrial coding and barcode systems such as Buskro and Domino.

Classic Wide-Format Graphics Platforms: Configured for white ink, varnish, or heavy-color channels in early premium configurations from brands like JHF, Flora, Wit-Color, and Liyu.

Specialized Industrial Manufacturing: Material deposition, thick-film coating, and precision micro-fluid spraying systems in electronics manufacturing.
