NMW 2004: Heidenhain’s linear encoder offers high accuracy

Chicago, IL— Heidenhain Corp. reported at NMW 2004 that its latest miniature, incremental, exposed, linear encoder—the LIF400 series—was originally designed for the semiconductor industry. With its postage-stamp-sized scanning unit and very high accuracy, these encoders are especially useful in the fiber stage manufacturing, or in any application developing positioning stages, or in very small settings.
With travel up to 1 meter, LIF400 maintains a long wave accuracy grade of
LIF400 also has a revolutionary type of grating, called Supradur, which offers an unusually high tolerance to contamination, such as oil, dust, and fingerprints. This gratring consists of precisely measured layers of glass and reflective material that prevents contaminants from interfering with the light-based, non-contact scanning principle.
LIF400's other features include optical limit switches that allow users to place limits anywhere directly on the scale, which enables the scale to be mounted closer to a motor than scales with magnetic switches. Also, the scale has a separate homing track with an integrated reference mark, which allows the encoder to differentiate on which side of the reference mark the scanning unit is located.
