Product Description
The Spectra Polaris PQ-512 / 35 AAA is a high-performance inkjet printhead engineered for heavy-duty industrial and commercial printing. Building upon the legendary reliability of the Spectra Nova and Galaxy series, the Polaris PQ-512 / 35 AAA provides a robust solution for production environments that require high-volume output without compromising on consistency or service life.
VersaDrop™ Technology for High-Volume Production
Featuring VersaDrop™ jetting technology, this printhead is designed for binary jetting with a native drop size of 35 picoliters. For applications requiring higher ink coverage, the drop size can be adjusted up to 80 picoliters, supporting resolutions up to 800 dpi. With 512 independent channels and high-frequency firing capabilities, it is the ideal choice for high-speed solvent and UV-curable wide-format printers.
Key Features & Industrial Performance
- Broad Ink Compatibility: Fully compatible with UV-curable, aggressive organic solvents, and aqueous inks, including specialized maintenance fluids.
- Precision Viscosity Control: Equipped with internal heaters and temperature sensors that allow precise jetting at temperatures up to 60°C (140°F), ideal for high-viscosity fluids.
- Field Repairable & Modular: The unique design allows for the individual replacement of 256-channel modules. Alignment is simplified via an integral mounting bezel, requiring no special tools or complex recalibration.
- Dual Ported Interface: Each module is dual-ported to facilitate efficient priming, flushing, and ink recirculation, ensuring maximum nozzle health.
- Configuration Flexibility: Supports both single-color (200 dpi) and two-color (100 dpi) operations to fit various carriage designs.
