A new sealed incremental linear encoder with a resolution of 0.1 micron and a measuring length up to three metres is now available from Heidenhain (GB), of Burgess Hill, in West Sussex.

Typical use for the LF 183 encoder is machine tools and automation requiring high precision slideway positioning. It is available in two accuracy grades of ± 2 microns and ± 3 microns. Central to the encoder accuracy is the use of the Heidenhain high-definition DIADUR phase grating on a steel carrier as the measuring standard which has a defined thermal linear expansion coefficient of 10ppm/K.

The fully sealed housing and mechanical design of the encoder ensures error-free operation, even under the most difficult conditions, such as in a machine tool application where vibration and shock can be a problem.

The LF 183 encoder is able to overcome exposure to swarf and other contaminants from the working environment and has a maximum traversing speed of 60m/min.

A version designated LF 183C is also available using closer pitched distance-coded reference marks so absolute position is determined within a maximum traverse of only 20mm.
