For ASM58N-F1AK1R0GN-1416, EncoderWorks can provide a custom compatible replacement focused on Gray-code SSI mapping, 14/16-bit position scaling, and Ø10 mm recessed hollow-shaft installation. This model should not be treated like the 12/12 or 12/13 versions. The cable and shaft may look the same, but the controller must accept a much larger absolute word range.
The ASM58N-F1AK1R0GN-1416 is an SSI multiturn absolute encoder configuration with Gray code, 16-bit singleturn resolution, 14-bit multiturn range, 4.5–30 VDC supply, aluminum housing execution, Ø10 mm x 30 mm recessed hollow shaft, K1 1 m cable connection, and radial cable exit. The replacement should preserve 65536 steps per revolution and 16384 turns.
The first failure boundary is SSI word length. Clock+ / Clock- and Data+ / Data- must remain true RS422 differential pairs, but correct wiring alone does not guarantee correct position. If the PLC expects 12/12, 12/13, or binary decoding, the SSI frame can be stable while the reported absolute value is wrong.
This replacement fails when SSI communication is present, but the PLC reads the wrong position because Clock/Data pair assignment, Gray decoding, 14/16-bit word length, monoflop timing, or cable shielding does not match the original encoder. That is a signal-chain and parameter failure, not simply a sensor failure.
The second boundary is input and shaft behavior. V/R changes counting direction, while PRESET 1 can reset the electrical reference. The Ø10 mm recessed hollow shaft must enter within the 15–30 mm insertion range, and the torque rest must prevent housing rotation without adding offset load.
The replacement decision should first confirm Gray SSI format, 16-bit singleturn and 14-bit multiturn mapping, K1 1 m radial cable assignment, Clock/Data differential wiring, 20 ±10 µs monoflop behavior, V/R direction input, PRESET 1 zero-set logic, 4.5–30 VDC supply, Ø10 mm recessed shaft fit, insertion depth, torque rest contact, shield grounding, and offset limits. EncoderWorks treats ASM58N-F1AK1R0GN-1416 as an industrial encoder custom compatible solution where SSI word length and Ø10 recessed-shaft mechanics decide field reliability.
Typical production lead time: 15 working days.
