The ASM58N-F2AK1R0BN-1213 multiturn absolute encoder can be replaced directly with our fully compatible model. Using a standard Ø58 mm body and SSI serial interface, this replacement ensures identical electrical and mechanical performance. With optically isolated RS422 signal output, it delivers interference-free position data transmission. Typical production time is 10 working days, suitable for urgent repair or OEM replacement demands.
This 30-bit multiturn encoder provides 65,536 steps per revolution and 16,384 turns, offering high-resolution control for automation and motion systems. It supports both direction and zero-set configuration, enhancing system flexibility. Its rugged hardware and reliable optical design make it ideal for continuous operation in industrial automation, material handling, and process machinery.
