Abstract

A linear encoder for use with a guide assembly includes a scale (21), a head (22) for scanning the scale (21), and mounting elements (30) for releasably attaching the scale (21) to the guide rail (11) of the guide assembly, with the mounting elements (30) being arrangeable outside of the mounting surface (14) of the guide rail (11) and having stop surfaces (31, 32) extending perpendicular to the longitudinal direction (X) of the guide rail (11) for a parallel alignment of the scale (21) along the guide rail (11) and encompassing and engaging reference surface (15, 16) of the guide rail (11).
