Spectra SE128 Printhead

The Spectra SE 128 jetting assembly boasts serial-to-parallel converters used to determine which jets to initiate, with both simultaneous and individual activation possible. The optional Head Interface Board of Spectra SE 128 allows users to daisy-chain image data into one serial stream to minimize data interface hardware requirements. Pumping chambers inside each channel in Spectra SE 128 are actuated by a high voltage fire pulse with controlled slew rates.

Spectra SE 128 ideal for fast moving, high performance printer carriage designs.
General compatibility with a wide range of fluids makes Spectra SE-128 AA jetting assembly extremely versatile.
