When the SAG-SL00G-1213-B120-CAW multi-turn encoder becomes difficult to obtain or delivery schedules exceed project timelines, we provide a purpose-built SSI technical solution to maintain operational stability. This replacement is engineered to address urgent maintenance demands and cost pressure without compromising performance. Production is typically completed within 15 working days, and we support low-quantity, non-standard configurations to match specific mechanical or electrical requirements. This flexible supply model helps reduce downtime and simplifies upgrade or retrofit processes.
The solution integrates an SSI interface based on RS422 transmission, ensuring stable serial communication in electrically demanding environments. With up to 13-bit resolution per revolution and 12bit multi-turn counting capability, it provides reliable position tracking for systems requiring precise rotational measurement. The adjustable clock frequency range from 100 kHz to 2 MHz allows seamless integration with various motion controllers and PLC platforms. Operating voltage between 10–30 VDC ensures compatibility with standard industrial power systems while maintaining efficient energy consumption.
Mechanically, the encoder is built into a 58 mm compact housing designed for continuous-duty applications. The structure supports rotational speeds up to 12,000 RPM (3,000 RPM for hollow shaft versions) and operates steadily within a temperature range of –40°C to +85°C. Protection levels reach IP65 on the enclosure side, with enhanced sealing options available when higher ingress resistance is required. Optional incremental output and preset functionality are available to support speed monitoring and zero-position adjustment, enabling straightforward adaptation to complex automation systems.
