Spectra Galaxy PH 256/30 AAA
Spectra Galaxy PH 256/30 AAA is a high performance, robust and reliable printhead designed for a broad range of industrial and commercial printing applications such as wide format graphics, addressing, and packaging at resolutions up to 900 dpi.
Spectra Galaxy Printhead 256/30 AAA is an ink jet printhead offering complete fluid support and signal processing capabilities for a wide range of jetting fluids. Within the printhead’s jetting assembly, four electrically independent piezoelectric slices, each with 64 addressable channels, are combined to provide a total of 256 jets. The nozzles are arranged in a single line at a 0.010 inch distance between nozzles.
The jetting assembly contains serial-to-parallel converters for selecting which jets to fire. The channels are daisy-chained into two serial data streams using the Head Interface Board. A high-voltage fire pulse with controlled slew rates is used to actuate the pumping chambers within each channel. The fluid interface is through the on-head reservoir, which has an integrated filter and fluid level sensor.
These Spectra heads are manufactured in the US and passed Dimatix Spectra US quality control tests to ensure the best durability. It carries a manufacturer product warranty.
This permits tight control over the fluid supply and also helps maintain a meniscus vacuum, used to prevent fluid weeping and air ingestion at the nozzles. An additional pneumatic interface allows for an external deaeration vacuum (incorporating Dimatix’s patented lung technology). For thermal control, a heater cartridge
