Product description
Heidenhain 557 644-19 identifies an absolute sealed LC 493F linear encoder for direct position measurement on linear machine axes. The ID number belongs to the version with a measuring length of 1140 mm. Its DIADUR scale contains an absolute track and uses a grating period of 20,000 µm. The measuring step is 50 nm and accuracy grade is ±5.0 µm. Absolute position is output through the Fanuc 02 serial interface. Supply voltage ranges from DC 3.6 V to 5.25 V. Electrical connection is provided by a 14-pin male connector. Protection is IP53 when installed according to manufacturer specifications; IP64 is possible with sealing air connected. The operating-temperature range is 0 to +50 °C and maximum traversing speed is 180 m/min. For the 1140 version, the HEIDENHAIN product information specifies an overall length of ML + 138 mm, resulting in 1278 mm. The profile is 18 mm wide. Across the housing and scanning unit, maximum height is 58.2 mm. Cable, cable outlet and additional installation clearance are not included in these external dimensions. Documented product weight is approx. 0.83 kg. The slim device form arranges the scale housing and moving scanning unit within a clearly defined mechanical envelope along the machine guideway. Required clearances for the housing and cable are separate planning values. The complete 1278 × 18 × 58.2 mm envelope provides the basis for installation, storage and transport planning. ID number, measuring length, Fanuc version and connector type together provide the exact technical assignment of this LC-493F linear encoder completely.
