Modular encoder system U-ONE Generation II (LWL) for position and speed monitoring.
Measurement directly on the application shaft, with connection via just one fiber optic cable to evaluation/function modules in the switchboard.
Available with hollow shaft Ø 20 mm or solid shafts up to Ø 14 mm (flange or foot mounting).
Resolution: 13-bit singleturn / 15-bit multiturn.
Interfaces: PROFIBUS, PROFINET, incremental (HTL), and analog 4–20 mA.
Up to 15 programmable switching outputs for speed and position monitoring.
Optional certification for safety applications up to SIL 2 / PL d.
