4-20MA、0-20MA Absolute Encoder SAS/M58

Core components are 100% domestically manufactured, ensuring supply chain stability and reliable product quality.
High-precision magnetic sensing technology is adopted, supporting both single-turn and multi-turn encoder configurations.
Supports analog outputs (current:4-20MA、0-20MA), compatible with multiple control interfaces.
Single-turn resolution up to 16 bits; multi-turn resolution up to 14 bits for accurate position measurement.
High resistance to shock and vibration, suitable for harsh industrial environments.
Built-in reverse-polarity and short-circuit protection reduces the risk of damage caused by wiring errors.
