Abstract: A mounting device for mounting a length measuring system extending in a measurement direction, the mounting device including a basic body, a steadying device attached to the basic body and a retainer attached to the basic body. A length measuring system that extends in a measurement direction is fixable on the basic body by clamping between the steadying device and the retainer, wherein the basic body and the retainer are embodied for guiding the retainer on the basic body longitudinally in a manner fixed against relative rotation in a direction of the steadying device by an adjusting element.

Abstract: A linear encoder that includes a housing having: an elongated hollow profile section including a first face end and a second face end; a cap disposed on the first face end; and a seal which is disposed in sealing fashion between the hollow profile section and the cap, wherein the seal includes an electrically conductive connecting element. The linear encoder further includes a scale made of electrically nonconductive material, wherein the scale is disposed inside the housing and the scale includes a measuring graduation that is scannable by a scanning unit, which is movable in a measurement direction relative to the housing. The linear encoder includes a shunt made of electrically conductive material, wherein the shunt is mounted on the scale and extends in the measurement direction and wherein the electrically conductive connecting element is configured so as to establish an electrical connection between the shunt and at least one of the hollow profile section and the cap.

Abstract: A scanning unit including a light source for illuminating a scale by a light beam and a detector for detecting the light beam which has been modulated by the scale as a function of a relative position between two objects. An inner chamber of the scanning unit in which the light beam extends is closed off in a dust-proof manner against an outer chamber, and the inner chamber is closed off by a transparent body, through which the light beam passes. The inner chamber is connected with the outer chamber via a filter which is dust-proof, but permeable to gas and vapor.
