The 566084 AC58/1212EK.42SBB-F0 SSI Absolute Encoder is available through our fully customized replacement solution, replicating the original encoder’s mechanical dimensions, electrical parameters, and SSI communication protocol. This ensures true one-to-one compatibility with existing systems, minimizing installation risks. Optional non-standard modifications, such as custom shafts, reinforced housings, or alternative connectors, can also be provided. Our standard production cycle is approximately 15 working days, offering reliable supply and minimizing downtime.
This encoder was widely applied in automation systems, robotics, and CNC machinery where accurate absolute positioning was crucial for synchronized operations. Its SSI interface ensured stable, interference-resistant communication, enabling efficient and precise motion control. The replacement encoders we manufacture maintain these core capabilities while also introducing modern improvements such as enhanced materials and refined production techniques, providing long-term durability and stability.
