Heidenhain 390925-02 is a graduation drum with a centring collar from the ERM 200 series. It is the passive measuring standard for a modular, bearingless, magnetoresistive angle encoder used on hollow-shaft axes, rotary tables and machine-tool drives. The drum is mounted directly on the rotating axis and works with the matching scanning head to provide incremental angular-position signals to the CNC control. A graduation of 1024 lines per revolution and a 395 µm graduation period provide the basis for angular measurement. The documented graduation accuracy is ±7.0 arc seconds. Mechanical dimensions are 128.75 mm outside diameter, 80.0 mm inside diameter and a 95.0 mm pitch-circle diameter. These dimensions must be matched precisely to the existing axis and scanning-head arrangement. The magnetoresistive measuring principle is intended for demanding machine environments where coolant, oil, metal chips and vibration may occur. An integrated reference mark permits repeatable zero-position referencing after the machine is restarted. The maximum permissible operating speed is 13,000 min⁻¹, and the working-temperature range extends from −20 up to +100 °C. The measuring body is rated IP67. The ERM-200 architecture uses a separately mounted measuring drum and scanning head; the ERM-200 measuring system must be assigned by its complete identification data. Compatibility within the ERM 200 family still depends on the complete identification number. This Heidenhain 390925-02 is new and supplied in its original packaging from stock in Germany.
