For ASM58N-F1AAAA0BN-1416, EncoderWorks can provide a custom compatible replacement focused on binary SSI pin mapping, axial M23 connector clearance, and 14/16-bit position scaling. This model should not be treated like the radial connector version. The SSI format may be similar, but axial exit changes plug clearance, cable bend direction, shield routing, and how the connector load affects the recessed-shaft installation.
The ASM58N-F1AAAA0BN-1416 is an SSI multiturn absolute encoder configuration with binary 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, 12-pin M23 connector, and axial exit. The replacement should preserve 65536 steps per revolution and 16384 turns.
The first failure boundary is SSI pin accuracy. Clock+ / Clock- and Data+ / Data- must remain true RS422 differential pairs. If the axial M23 pinout is copied incorrectly, or if reserved pins are connected as active conductors, the SSI word can become shifted, unstable, or correctly transmitted but wrongly decoded.
This replacement fails when SSI communication is present, but the PLC reads the wrong position because M23 pin assignment, binary decoding, 14/16-bit word length, monoflop timing, or shield grounding does not match the original encoder. That is a signal-chain and parameter failure, not simply a sensing failure.
The second boundary is axial connector 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 rear connector must not force radial, axial, or angular preload into the mounting.
The replacement decision should first confirm binary SSI format, 16-bit singleturn and 14-bit multiturn mapping, axial M23 pin 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, connector clearance, and offset limits. EncoderWorks treats ASM58N-F1AAAA0BN-1416 as an industrial encoder custom compatible solution where SSI pin accuracy and axial connector mechanics decide field reliability.
Typical production lead time: 15 working days.
