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.
