Available. TTR_ERA_4400_14000_RA. The Heidenhain TTR ERA 4400 14000 RA is a scale drum designed for incremental modular angle encoders, offering precise angular measurement solutions for industrial applications. This model features a line count of 14,000, providing a grating period of 40.000 µm and a graduation accuracy of ±2.5''. The drum's geometry includes an outer diameter of 178.55 mm, an inner diameter of 120 mm, and a hole circle diameter of 140 mm, with six holes of 5.5 mm diameter, all equipped with a centering collar. It operates with coded reference marks, with a nominal increment of 1,000 grating periods. The mechanical permissible speed without mechanical fault exclusion is 8,750 min⁻¹, and with mechanical fault exclusion, it is 4,500 min⁻¹. This scale drum is ideal for applications requiring high precision and reliability in angular position sensing.
