Genuine original Xaar 502 GS40 UV piezoelectric printhead optimised for high-laydown UV-curable inks delivering robust coverage and industrial reliability in graphics coding and packaging applications.
Product Overview
The Xaar 502 GS40 UV is a precision piezoelectric drop-on-demand printhead featuring PrecisionPlus actuator architecture for uniform drop formation, accurate dot placement, and high fluid deposition when using UV-curable inks. Incorporating 500 active nozzles in a single row at 180 npi native density across a 70.5 mm print swathe, it supports greyscale operation with large drop volumes (40 to 160 pL) across 6 grey levels. Engineered for high-opacity and heavy-laydown UV applications, it features Ultra High Viscosity capability, an integrated WFG nozzle guard, and internal filtration. Factory-sealed British OEM construction ensures complete chemical compatibility with demanding UV ink formulations in industrial printing environments.

Technical Precision & Operational Advisory
- Electrostatic Discharge (ESD) Protection: Always wear a grounded ESD wrist strap and work on an ESD-safe surface when handling sensitive electronic parts. Piezoelectric actuators are susceptible to static damage.
- Power Isolation Warning: Fully power off the equipment and disconnect main power sources before replacing parts, connecting flexible flat cables (FFC), or handling fluid lines.
- UV Light Shielding & Handling: Protect the printhead nozzle plate from stray ambient UV light and LED curing lamps during installation to prevent accidental ink curing inside the nozzles.
- Professional Installation: It is strongly recommended to have replacement performed by a certified technician following standard technical protocols. Always use new ribbon cables during installation.
