Heidenhain 557644-19 is an absolute sealed linear encoder from the LC 493F series with a measuring length of 1140 mm. The unit uses the Fanuc02 serial interface for position feedback in compatible CNC machining centres, grinding machines and milling machines. Its accuracy class is ±5.0 µm, and the measuring step is 50 nm. The compact LC 493F profile supports installation where machine space is limited; its housing adds 138 mm beyond the measuring length for installation planning. A graduation period of 20,000 µm and absolute position acquisition eliminate the need for a reference run after the control is switched on. The housing is rated IP53; with optional sealing air, protection increases to IP64 to help keep coolant spray, oil mist and contamination away from the measuring system. The operating-voltage range is DC 3.6 V to 5.25 V and is intended for the matching Fanuc control interface. Maximum permissible traverse speed is 180 m/min. A 14-pin male connector provides the electrical connection. Heidenhain 557644-19 is supplied as a new item in its original packaging and is available from stock in Germany. Before installation, compare the full identification number, measuring length, total length, interface, connector and mounting geometry with the machine documentation. The complete 557644-19 designation is decisive for assignment.
