Description:
• The Polaris PQ-512 / 15 AAA Printhead has 512 independent channels arranged in multiple rows at 200 dots-per-inch spacing for single color operation, or 100 dots-per-inch spacing for two color operation.
• The printhead is designed for binary jetting using a 15-picoliter native drop size with 8-meters per second nominal drop velocity for jetting fluids in the 8 to 20 centipoise range. Using VersaDrop jetting technology, the printhead is capable of adjustable binary operation at drop sizes up to 30 picoliters with resolutions up to 1000 dpi.
• Building upon the legendary reliability and performance of the Spectra Nova and Galaxy printheads, the Polaris PQ-512 AAA family of printheads uses field proven materials and a repairable design to deliver a long service life and consistent output. And by leveraging the inherent flexibility of the Q-Class platform, the Polaris PQ-512 AAA offers even greater jetting performance, nozzle packing density, and configuration flexibility. 
• The PQ-512 / 15 AAA Printhead is compatible with a broad range of inks, including UV-curable, aggressive organic solvent and aqueous inks and associated maintenance fluids.
• The unique design of Polaris PQ-512 / 15 AAA Printhead allows each 256-channel module to be replaced and accurately registered in the field with no special tools or recalibration. An integral mounting bezel with precision registration points enables drop-in alignment with other carriage features.
• Two electrical connectors contain eight serial data lines that supports fire frequencies in excess of 50 kHz.
• The flexible fluid interface allows single and two-color operation. Each 256-channel module is dual ported to facilitate easy priming, flushing and ink recirculation. Heaters and temperature sensors allow precise control of ink viscosity at jetting temperatures up to 60°C.

Application:
The Spectra Polaris PQ-512/15 AAA Printhead is a high performance Inkjet Printhead designed for a broad range of industrial and commercial printing applications at resolutions up to 1000 dpi. Robust construction and repairable design make it ideal for solvent, UV and aqueous based wide format printers built for demanding production environments.
