1) The LIP exposed
linear encoders are characterized by very small measuring steps together with very high accuracy and LIP for very high accuracy 0.128 µm repeatability. As the measuring standard they feature a DIADUR phase grating applied to a graduation carrier of glass ceramic or glass.

They feature high LIDA exposed linear encoders are specially designed for high traversing speeds up to 10 m/s, and are particularly easy to mount with various mounting possibilities. Steel scale tapes, glass or glass ceramic are used as carriers for AURODUR or METALLUR graduations, depending on the respective encoder.
