We provide a direct 1:1 customized replacement for the ASM58N-F1AK1AHBN-1213 multiturn encoder, designed for quick delivery within 10 working days. The replacement model fully replicates the original’s mechanical dimensions, electrical pinout, and SSI communication protocol, enabling an effortless drop-in replacement in any automation or drive control environment.
The encoder features a high-resolution 30-bit multiturn output, transmitting precise shaft position data via an RS422 SSI interface. Its optically isolated circuitry ensures interference-free operation, while the recessed hollow shaft design allows simple mounting without couplings. This model’s hardware architecture eliminates microcontroller-based latency, offering fast, reliable data synchronization in demanding motion systems.
