Abstract: A position measuring device includes a position detection unit, which may be used to process positional signals that result from scanning a code track by a scanning unit, into digital positional values, a first interface unit for the communication with a control unit via a data transmission channel, and a second interface unit for the communication with at least one peripheral unit. The first interface unit is a hard-wired interface, and the second interface unit is a wireless radio interface.

Abstract: An angle measuring instrument having a device for determining a shaft angular position within one shaft rotation, and a device for determining a number of executed shaft rotations having a gear including at least one gear for converting the shaft rotary motion into rotary motion having a defined reduction ratio. The gear unit includes at least one gear wheel which rotates in a defined ratio to the shaft rotary motion. Devices are provided for generating sensor signals which are positionally dependent and are dependent upon the shaft rotations, in which the detecting device inductively scans reduced rotational movements of the shaft, and has alternating electrically conductive and electrically non-conductive graduation regions and a scanning device, movable relative to the graduation structure, including a device for generating a homogeneous electromagnetic field and a sensor device to scan the graduation structure and to transmit sensor signals which are dependent upon the shaft rotations.
