Detailed Product Description
The Spectra SM-128 AA is a high performance, robust and reliable jetting assembly
The Spectra SM-128 AA is a high performance, robust and reliable jetting assembly designed for a broad range of
industrial and commercial printing applications such as wide format graphics, addressing, and packaging at resolutions up to 600 dpi.
The SM-128 AA is a highly compact and lightweight
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
SM-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.
