Uses high-precision optical sensing technology to provide reliable single-turn and multi-turn encoder solutions. Supports the SSI interface with clock frequencies up to 2 MHz for fast and precise data transmission. Optional TTL/HTL incremental outputs are available to meet a wide range of control and feedback requirements. Single-turn resolution is available up to 25 bit, with multi-turn resolution up to 14 bit for high-accuracy position measurement. High shock and vibration resistance, together with protection ratings up to IP66, ensures reliable operation in demanding industrial environments. Built-in reverse polarity and short-circuit protection helps minimize the risk of damage caused by incorrect wiring.y and short-circuit protection effectively reduces the impact of installation errors on the encoder.
