Heidenhain 557679-06 is an absolute sealed linear encoder from the LC 183 series for precision CNC machine tools and machining centres. It supplies the absolute position immediately after switch-on, so the machine does not require a reference traverse. A DIADUR glass scale with absolute and incremental tracks has a 20 µm graduation period and a thermal-expansion coefficient of approximately 8 × 10⁻⁶ K⁻¹. With a measuring length of 640 mm and a 10 nm measuring step, the encoder achieves an accuracy class of ±5.0 µm. Data is transmitted through the synchronous serial EnDat 2.2 interface together with an additional 1 Vpp incremental signal. Overall installation length is 761 mm. The electrical interface uses a 14-pin flange connector; the connection cable is supplied separately, and cable lengths up to 150 m are supported. The IP 53 rating to EN 60529 protects against dust and splashing water. With sealing air connected, the protection rating increases to IP 64. Supply voltage is 3.6 V to 5.25 V, with current consumption below 300 mA. Maximum traverse speed is 180 m/min, and operation is permitted within the specified temperature range. Compare the complete identification number, installation length, interface and mounting arrangement before replacement. The full 557679-06 designation must match the installed encoder. Available from our warehouse in Germany.
