Heidenhain 605379-91 is an LS 477 incremental linear scale with a measuring length of 1020 mm. This enclosed scale uses a DIADUR graduation with a 20 μm grating period and is intended for demanding positioning tasks on numerically controlled machine tools. Applications include milling centres, boring mills, machining centres, lathes and grinding machines whose feed axes operate in a closed position-control loop and require direct position measurement. With an accuracy grade of ±5 μm, Heidenhain 605379-91 provides precise measuring signals for metal-cutting production. Its TTL interface supports integration into existing CNC control environments. Maximum traversing speed is 120 m/min. The unit operates from DC 5 V ± 0.25 V and consumes less than 140 mA, supporting highly dynamic axis movements. When fitted in accordance with the installation instructions, the scale is rated IP 53 against dust and splashing water; optional sealing air supplied through a DA 400 unit increases protection to IP 64. Required driving force is no more than 5 N, and the operating-temperature range is 0 °C to 50 °C. The glass scale has a thermal expansion coefficient of αtherm ≈ 8 × 10⁻⁶ K⁻¹. Vibration and shock resistance are qualified to EN 60068, and cable lengths of up to 100 m are possible. Available directly from our warehouse in Germany.
