For users facing extended lead times or limited sourcing channels for the SAG-SL00G-1213-B150-CAW multi-turn absolute encoder, we provide a reliable SSI custom solution engineered for industrial continuity. Our replacement approach focuses on reducing procurement cost while maintaining full functional compatibility. Standard production is typically completed within 15 working days, including support for low-volume and application-specific customization. This ensures minimal downtime for automation systems, retrofit upgrades, or urgent maintenance projects.
The solution is designed around a high-stability SSI (RS422) communication interface, supporting transmission speeds up to 10 MBit/s for consistent and noise-resistant data transfer. It delivers precise multi-turn positioning with up to 16-bit single-turn resolution and 14-bit multi-turn capacity, ensuring accurate angle and revolution tracking in demanding motion control environments. Operating voltage ranges from 10–30 VDC, with low power consumption and configurable clock frequency between 100 kHz and 2 MHz to match various control architectures.
Built within a compact 58 mm heavy-duty housing, the encoder supports continuous operation up to 12,000 RPM (3,000 RPM for hollow shaft configurations). Protection levels reach IP65 on the enclosure side, with extended sealing options available. The mechanical structure is optimized for industrial durability, featuring a stainless steel shaft and reinforced internal components. Optional incremental output, preset functionality, and multiple flange or shaft variants allow seamless adaptation to different machine designs and installation requirements.
