Large through-bore, bus-type output for easier installation.
High-precision optical sensing technology, available as single-turn or multi-turn encoders.
Single-turn resolution up to 25 bits; standard multi-turn revolutions up to 14.
ProfiNet I/O bus with a maximum data rate of 100 Mbit/s, GSDML version 2.44, or customizable for a higher number of revolutions.
Excellent resistance to magnetic field interference, with LED status indication.
Equipped with reverse-polarity and short-circuit protection, effectively reducing the impact of installation errors on the encoder.
