For projects experiencing sourcing delays, rising procurement costs, or limited availability of the SAG-SL00G-1212-C100-CRW multi-turn absolute encoder, we provide a professionally engineered SSI technical solution designed for rapid deployment. Our replacement solution is developed for industrial users who require stable performance without extended downtime. Standard production lead time is typically within 15 working days, including support for small-quantity, non-standard customization. This flexible manufacturing approach allows users to maintain system continuity while significantly reducing overall acquisition cost compared to long-cycle supply channels.
The solution is based on a high-speed SSI (RS422) communication interface, supporting transmission rates up to 10 MBit/s. It delivers precise position feedback with 16-bit single-turn resolution (65,536 steps) combined with 14-bit multi-turn counting (16,384 revolutions), ensuring accurate tracking across extended rotational movement. Operating voltage ranges from 10–30 VDC with low power consumption between 1 W and 1.5 W, depending on configuration. Clock frequency is adjustable from 100 kHz to 2 MHz, enabling compatibility with a wide range of industrial PLC and motion control systems.
Mechanically, the encoder features a compact 58 mm industrial housing constructed from aluminum with an optional stainless steel version for demanding environments. The stainless steel shaft and reinforced internal code disc enhance durability under continuous operation. The unit supports speeds up to 12,000 RPM (3,000 RPM for hollow shaft versions) and operates reliably in temperatures from –40°C to +85°C. Protection level reaches IP65 on the housing side and IP64 on the shaft side, with optional sealing up to IP66. Additional configuration options include 1024 PPR incremental output for speed monitoring, preset functionality, and multiple flange or shaft styles to match diverse installation requirements.
