We provide a precise 1:1 replacement for the ASM58N-F2AK1RHGN-1212 multiturn encoder, available with a 10-working-day lead time. The replacement is fully compatible with the original model’s mechanical and electrical characteristics, including the SSI communication protocol, pin layout, and hollow shaft configuration. This ensures straightforward installation and plug-and-play operation in existing setups.
Featuring 30-bit multiturn accuracy, the encoder transmits position data through a high-speed RS422 SSI interface with up to 2 Mbaud transfer rate. The optically isolated circuitry enhances data reliability, while the hardware encoder structure guarantees instant signal output synchronized to the control clock. With its durable build and vibration-resistant design, this encoder provides consistent performance in industrial automation and machinery environments.
