Beschreibung
Zusammenfassung:	A linear encoder that includes a scale supporting a measurement graduation and an assembly that includes a support. The scale is fastened on the assembly by a fastener, wherein the fastener has a structure that makes a temperature-dependent linear expansion of the support in relation to the scale possible in case of temperature changes. The linear encoder includes a holder in a position in a measuring direction, wherein the holder fastens the scale to a body to be measured by the linear encoder at a fixed point while bypassing the support. In addition, the assembly is fastened by the support on the body to be measured by the linear encoder.
