Product description
The Heidenhain 385 489-06 incremental rotary encoder combines model designation ERN 1381.020-2048 with 2048 lines and a sinusoidal output signal of approximately 1.05 Vss. Power is supplied at 5 V DC with a tolerance of ±5 %. For the 2048-line version, system accuracy is ±20 arc seconds and the cutoff frequency is at least 210 kHz. One reference mark provides position referencing. Mechanically, the device belongs to the ERN-1381 series with integral bearing and mounting via a stator coupling. The tapered shaft has a functional diameter of 9.25 mm and a taper ratio of 1:10. The mechanically permissible speed is up to 15,000 min⁻¹. These data describe the encoder version itself; motor and drive configurations additionally differ in their system-side connection and installation data. Electrical connection is provided by a straight, double-row 14-pin connector with locking mechanism. The cable outlet can be routed axially or radially according to the installation situation. This allows the connection direction and available installation depth to be considered when comparing the installed encoder. The exact product information assigns external dimensions of 130 × 120 × 90 mm and a weight of 1.0 kg to identification number 385 489-06. Key comparison characteristics include identification number, model designation, line count, interface, supply voltage and shaft geometry. The combination of 2048 lines, 1.05 Vss and tapered shaft describes the specific encoder version within the series. Similar ERN-1381 versions can differ in line count, connection or mechanical design. A unique assignment exists only when the complete suffix 06 and model ending 2048 also match.
The item supplied will have the stated manufacturer or type number and the stated condition category. Serial number, manufacturing date, labels, colour, packaging and normal signs of use or storage may differ. Specifications
