Abstract: A scanning unit for a position measuring device for scanning a measuring graduation thereof, includes a scanning structure provided on a carrier and formed such that, by interaction of electromagnetic radiation, with the measuring graduation and the scanning structure, a periodic stripe pattern is generated. A detector arrangement includes detector elements of different phases that generate output signals having a phase shift. The detector elements form a periodic pattern, and each detector element is assigned exactly one region of the scanning structure referred to as a bar. The detector elements are combined to form two detector groups. Detector elements of the same phase belong to the same detector group, and the detector elements within one detector group are interconnected. The bars of each detector group cover an active area of equal size. The area center of gravity of the area covered by the bars of the detector groups coincide.

A detector arrangement is provided for detecting the stripe pattern, which is made up of a plurality of detector elements of different phases, arranged one after another, that generate output signals having a phase shift represented by those phases, the arrangement of detector elements of different phases one after another forming a periodic pattern, and each of the detector elements being assigned exactly one region of the scanning structure referred to as a bar, and the detector elements being combined to form two detector groups such that at least detector elements of the same phase belong to the same detector group, and the detector elements within one detector group being interconnected for generating a detector signal. The bars of the scanning structure are formed and arranged such that the totality of the bars assigned to the first detector group and the totality of the bars assigned to the second detector group in each case cover an active area of equal size on the carrier of the scanning structure. The area center of gravity of the area covered by the totality of the bars assigned to the first detector group on one hand, and the area center of gravity of the area covered by the totality of the bars assigned to the second detector group on the other hand coincide.

Abstract: An angle-measuring device including a first component group and a second component group, the component groups being disposed in a manner allowing rotation relative to each other by a bearing. The first component group includes a housing having a connecting device, as well as a scanning unit. The second component group includes a shaft to which a code disk is attached, and a flow channel having a directional component parallel to the axis. The angle-measuring device is configured such that a negative pressure is able to be applied to the connecting device, so that a fluid surrounding the angle-measuring device with a pressure flows through the angle-measuring device to remove contaminants by suction. At the applied negative pressure, a first mass flow of the fluid which flows through the flow channel is greater than a second mass flow which flows through the bearing gap.
