Product description
Identification number Heidenhain 390925-02 designates a TTR ERM 200 scale drum with centring collar. It forms the passive measuring standard of a magnetoresistive incremental modular angle encoder without integral bearing. The specific drum has 1024 lines per revolution and a 395 µm graduation period. Its inside diameter is 80 mm, outside diameter is 128.75 mm and pitch-circle diameter is 95 mm. Six M6 holes provide axial fastening. Graduation accuracy is ±7 arc seconds, while position error within one signal period is specified as ±9 arc seconds. Mechanically permissible speed is up to 13,000 min⁻¹. The operating-temperature range extends from −10 to +100 °C, and the assembly has an IP67 rating. The dimensional drawing shows an axial width of 15 mm. Together with the outside diameter, complete drum dimensions are Ø 128.75 × 15 mm in outside diameter × axial width order. Approximate manufacturer mass for the ERM 200 drum with 80 mm inside diameter and 1024 lines is 0.89 kg. Identifier 390925-02, the combination of 80 mm inside diameter and 128.75 mm outside diameter, and the line count distinguish this version within the ERM-200 series. Pitch circle, axial width and hole pattern are additional mechanical assignment data. Dimensions and weight form the final two specification rows.
