A custom compatible replacement for ESM58N-F3AIZR0BN-1213 can be supplied by EncoderWorks with the main check placed on EtherNet/IP configuration, 13/12-bit position mapping, and Ø15 mm recessed hollow-shaft fit. This model should not be treated like the Ø10 or Ø12 shaft versions. The larger recessed bore changes insertion-depth control, torque-rest contact, and offset sensitivity during installation.
The ESM58N-F3AIZR0BN-1213 is an EtherNet/IP multiturn absolute encoder configuration with binary code, 13-bit singleturn resolution, 12-bit multiturn range, 10–30 VDC supply, aluminum housing execution, Ø15 mm x 30 mm recessed hollow shaft, radial M12 Ethernet and power connection, and integrated 2-port switch.
The first failure boundary is EtherNet/IP setup. IP address, subnet, device identity, CIP encoder profile, assembly format, preset value, counting direction, and PLC module configuration must match the original installation. Link and Active LEDs may show traffic while the controller still rejects the position data.
This replacement fails when Ethernet link is present, but the PLC reads no valid position because EtherNet/IP configuration, 13/12-bit resolution mapping, preset value, or counting direction does not match the previous encoder. That is a network-parameter failure, not a sensing failure.
The second boundary is Ø15 mm recessed hollow-shaft mounting. This shaft is not solid and should not be treated as a simple through bore. The machine shaft must enter within the correct insertion range, and the torque rest must prevent housing rotation without forcing angular or radial offset.
The replacement decision should first confirm EtherNet/IP compatibility, CIP encoder profile, IP address handling, M12 D-coded port assignment, M12 A-coded supply, 13-bit singleturn and 12-bit multiturn mapping, binary code, preset value, counting direction, Ø15 mm recessed hollow-shaft fit, 15–30 mm insertion depth, torque rest contact, shield grounding, and offset limits. EncoderWorks treats ESM58N-F3AIZR0BN-1213 as an industrial encoder custom compatible solution where EtherNet/IP setup and Ø15 recessed-shaft mechanics decide field reliability.
Typical production lead time: 15 working days.
