For ESM58N-F2APNR0BN-1213, EncoderWorks can provide a custom compatible replacement focused on PROFINET device setup, 13/12-bit position mapping, and Ø12 mm recessed hollow-shaft fit. This model should not be treated like the 16/14-bit version. The Ethernet ports may look identical, but the PLC project must expect the same resolution, device name, module configuration, preset value, and counting direction.
The ESM58N-F2APNR0BN-1213 is a PROFINET multiturn absolute encoder configuration with binary code, 13-bit singleturn resolution, 12-bit multiturn range, 10–30 VDC supply, aluminum housing execution, Ø12 mm x 30 mm recessed hollow shaft, radial M12 Ethernet and power connection, and integrated 2-port switch.
The first failure boundary is PROFINET parameter agreement. Device name, IP address, GSDML module selection, update time, and RT/IRT communication setting must match the original controller project. Link and Active LEDs can be normal while the PLC still rejects the device because nominal and actual configuration are different.
This replacement fails when Ethernet link is present, but the PLC reports no valid position because PROFINET device name, module 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 recessed hollow-shaft installation. The 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 stop housing rotation without forcing angular or radial offset.
The replacement decision should first confirm PROFINET compatibility, GSDML configuration, device name, IP assignment, M12 D-coded port mapping, M12 A-coded supply, 13-bit singleturn and 12-bit multiturn mapping, binary code, preset value, counting direction, Ø12 mm recessed hollow-shaft fit, 15–30 mm insertion depth, torque rest contact, shield grounding, and offset limits. EncoderWorks treats ESM58N-F2APNR0BN-1213 as an industrial encoder custom compatible solution where PROFINET setup and recessed-shaft mechanics decide field reliability.
Typical production lead time: 15 working days.
