Spectra S-Class SM-128 AA Printhead

The SM-128 AA is a highly compact and lightweight jetting assembly designed specifically for inkjet 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.

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.

The fluid interface and electrical connection are at the top of the jetting assembly, allowing multiple mounting configurations. The dual-ported fluid interface facilitates flushing for quick change-overs and prevents drying fluids from clogging the system during non-use. Optional temperature control components and deaeration hardware are available.
