We provide an OEM-grade 1:1 replacement for the ASM58N-F3AK1AHGN-1212 multiturn absolute encoder, produced within 10 working days. This alternative version fully replicates the original model’s SSI communication standard, connector type, and shaft dimensions, allowing effortless integration into existing systems. It is a dependable solution for upgrading or maintaining precision motion equipment.
Featuring 30-bit multiturn resolution, this encoder offers highly accurate feedback data through an RS422 SSI interface supporting up to 2 Mbaud transfer rate. Its hardware-based design ensures direct data synchronization without microcontroller delay. The recessed hollow shaft design reduces installation space while enhancing mechanical alignment. With a robust aluminum housing and optically isolated signal channels, the encoder maintains reliability even in demanding industrial automation environments.
