For ESM58N-F2AIZR0BN-1213, EncoderWorks can provide a custom compatible replacement focused on EtherNet/IP setup, 13/12-bit position mapping, and Ø12 mm recessed hollow-shaft fit. This model should not be treated as a simple Ethernet encoder exchange. The device may show link activity, while the controller still reports parameter fault, wrong position, or no valid data exchange because IP configuration, assembly setup, scaling, or shaft insertion depth was not reproduced.
The ESM58N-F2AIZR0BN-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, Ø12 mm x 30 mm recessed hollow shaft, radial M12 Ethernet and power connection, and integrated 2-port loop-through switching.


The first failure boundary is EtherNet/IP configuration. IP address, subnet, device identity, CIP encoder profile, controller project, and cyclic data size must match the original installation. Link LEDs can be normal even when the encoder is not accepted by the PLC due to wrong configuration or parameter mismatch.
This replacement fails when Ethernet link is present, but the PLC has no valid position because IP settings, device 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 mounting. This is not a solid shaft and not a normal through-hollow shaft. The application shaft must enter within the defined insertion range, while torque rest contact prevents housing rotation. Wrong insertion depth, clamping position, or offset can damage bearings or create unstable feedback.
The replacement decision should first confirm EtherNet/IP compatibility, CIP profile settings, 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, Ø12 mm recessed hollow-shaft fit, 15–30 mm insertion depth, torque rest position, shield grounding, and offset limits. EncoderWorks treats ESM58N-F2AIZR0BN-1213 as an industrial encoder custom compatible solution where EtherNet/IP setup and recessed-shaft mechanics decide field reliability.
Typical production lead time: 15 working days.
