For automation systems encountering long procurement cycles or limited availability of the SAG-SL00B-1213-C100-CRW multi-turn absolute encoder, we provide a professionally engineered SSI technical solution. This replacement is developed to maintain operational reliability while significantly reducing sourcing cost. Standard production lead time is typically within 15 working days, including support for low-volume customization and mechanical adaptation. The solution is particularly suitable for retrofit projects, urgent spare replacement, and equipment upgrades where stable multi-turn positioning is required.
The encoder solution utilizes an SSI interface based on RS422 transmission, enabling high-speed data communication with strong resistance to electrical interference. It supports up to 13-bit single-turn resolution combined with 12-bit multi-turn counting, ensuring accurate tracking of both angular position and total revolutions. Operating voltage ranges from 10–30 VDC, with adjustable clock frequency between 100 kHz and 2 MHz to ensure compatibility with diverse motion control architectures.
Designed with a 58 mm heavy-duty housing, the unit withstands demanding industrial environments. It supports continuous rotation up to 12,000 RPM (3,000 RPM for hollow shaft configurations) and operates reliably within a temperature range of –40°C to +85°C. The enclosure protection level reaches IP65, with optional sealing enhancement available. Additional configuration options include preset positioning and auxiliary incremental output, enabling flexible integration into precision control and monitoring systems.
