For ASS58N-F1AK1R0GN-0016, EncoderWorks can provide a custom compatible replacement focused on Gray-code SSI mapping, 16-bit singleturn scaling, and Ø10 mm recessed hollow-shaft installation. This model should not be treated like the 12-bit or 13-bit versions. The mechanical format may look the same, but the controller must accept a 65536-step singleturn word with the same SSI timing, direction logic, and zero-set behavior.
The ASS58N-F1AK1R0GN-0016 is an SSI singleturn absolute encoder configuration with Gray code, 16-bit singleturn resolution, 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. It should be handled as a singleturn angle encoder, not as a multiturn feedback device.
The first failure boundary is SSI word interpretation. Clock+ / Clock- and Data+ / Data- must remain true RS422 differential pairs. If the PLC expects 12-bit, 13-bit, binary code, or a different clock pause, the SSI frame may be stable while the calculated shaft angle is wrong.
This replacement fails when SSI communication is present, but the PLC reads the wrong singleturn position because Clock/Data pair assignment, Gray decoding, 16-bit word length, PRESET 1 input, or V/R direction state does not match the original encoder. That is a signal-chain and parameter failure, not simply a sensing failure.
The second boundary is recessed-shaft installation. The Ø10 mm shaft is not solid and not a simple through bore. The machine shaft must enter within the 15–30 mm insertion range, and the torque rest must prevent housing rotation without creating radial, axial, or angular preload.
The replacement decision should first confirm Gray SSI format, 16-bit singleturn 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 ASS58N-F1AK1R0GN-0016 as an industrial encoder custom compatible solution where 16-bit SSI word accuracy and recessed-shaft mechanics decide field reliability.
Typical production lead time: 15 working days.
