Detailed Product Description
The Spectra SE-128 AA is a high performance, robust and reliable jetting assembly
industrial and commercial printing applications such as wide format graphics, addressing and packaging at resolutions up to 900 dpi.
The Spectra SE-128 AA is a highly compact and
light-weight jetting assembly designed specifically for
ink jet applications requiring multiple printheads packed
tightly together. These modules are ideal for fast
moving, high performance printer carriage designs.
General compatibility with a wide range of fluids makes
the SE-128 AA jetting assembly extremely versatile.
Two electrically independent piezoelectric slices, each
with 64 addressable channels, are combined to provide a
total of 128 jets. The nozzles are arranged in a single
line, at a 0.020 inch distance between nozzles.
The fluid interface and electrical connection are at the
top of the jetting assembly and several mounting
configurations are possible. This arrangement permits
for extremely tight packing in the print process
direction. The dual ported fluid interface facilitates
flushing for quick change-overs and for displacing
drying fluids with inert fluids during periods of non-use.
This jetting assembly contains serial-to-parallel
converters for selecting which jets to fire; all jets can be
fired simultaneously or individually. By using an
optional Head Interface Board, image data can be
daisy-chained into one serial stream to reduce the data
interface hardware requirements. A high voltage fire
pulse with controlled slew rates is used to actuate the
pumping chambers within each channel.
