RS485 / Modbus-RTU Absolute Encoder SAS/M58
Core components are sourced through a localized supply chain to support supply continuity and stable system operation. High-precision magnetic sensing technology supports both single-turn and multi-turn absolute encoder configurations. Supports RS485 proprietary communication or Modbus RTU for flexible data communication and system integration. Single-turn resolution up to 21 bit and multi-turn resolution up to 14 bit for precise position measurement. High shock and vibration resistance ensures reliable operation in demanding industrial environments. Built-in reverse-polarity and short-circuit protection helps protect the encoder against wiring errors.
