Large through-bore design with PROFINET interface simplifies installation and system integration. High-precision optical sensing technology supports both single-turn and multi-turn absolute position measurement. Single-turn resolution is available up to 25 bit, with standard multi-turn resolution up to 14 bit. PROFINET IO communication supports data rates up to 100 Mbit/s and PROFINET specification version 2.44, with higher multi-turn capacity available as a custom option. Excellent resistance to magnetic interference, together with LED status indication, enables reliable operation and convenient diagnostics. Built-in reverse polarity and short-circuit protection helps reduce the risk of encoder damage caused by incorrect wiring.
