Heidenhain 689681-10 is an absolute sealed linear encoder from the LC 485 series with a compact design and small cross-section. The unit provides an absolute position immediately after power-up, without a preceding reference run. Its measured value is transferred serially to the downstream electronics through the digital EnDat 2.2 interface. With a measuring length of 520 mm, a total length of 625 mm and an accuracy of ±5.0 µm, Heidenhain 689681-10 is suitable for CNC machining centres, milling machines, lathes and grinding machines. The encoder operates with sinusoidal 1 Vpp voltage signals and a measuring step of 10 nm. The stated grating pitch is 20.000 µm. A 14-pin flange connector provides a compact electrical connection to the control electronics. Mounting uses a type 14A end block and a mounting rail; neither is included in the scope of supply. The aluminium housing reliably protects the measuring standard and scanning head, while IP53 protection supports operation under typical manufacturing conditions. The permissible operating temperature range is 0 °C to +50 °C, and supply voltage is between 3.6 V and 5.25 V. Before replacement, compare the complete identification, measuring length, EnDat version, signal output, connector and mounting accessories with the installed LC 485 encoder. The end block and rail requirements must be considered during mechanical planning. Available directly from our warehouse in Germany.
