For systems experiencing procurement challenges or extended delivery cycles for the SAG-SL00B-1213-B120-CAW multi-turn absolute encoder, we provide a dedicated SSI custom solution engineered for industrial continuity. This replacement approach is designed to shorten lead time and reduce acquisition cost without affecting system reliability. Standard production is typically completed within 15 working days, and small-batch or application-specific adjustments are supported. This enables maintenance teams and OEM integrators to restore motion systems quickly while maintaining technical consistency.
The solution is built around a robust SSI (RS422) serial communication architecture, ensuring stable and interference-resistant signal transmission in demanding environments. It supports up to 13-bit single-turn resolution combined with 12-bit multi-turn capacity, delivering accurate position feedback across extended rotational cycles. The working voltage range of 10–30 VDC and configurable clock frequency between 100 kHz and 2 MHz allow seamless adaptation to various PLC and drive control platforms.
Mechanically, the encoder adopts a 58 mm compact industrial housing with reinforced internal components for continuous-duty operation. It supports rotational speeds up to 12,000 RPM (3,000 RPM for hollow shaft versions) and operates reliably from –40°C to +85°C. The enclosure protection reaches IP65 on the body side, with enhanced sealing options available when higher ingress resistance is required. Optional incremental output and preset functionality can be configured to meet advanced motion monitoring and zero-position setting requirements.
