OCD-EEC1B-1416-B150-PCM EtherNet/IP DLR and Ø15 Hollow Shaft

For OCD-EEC1B-1416-B150-PCM, EncoderWorks can provide a custom compatible replacement focused on EtherNet/IP DLR continuity, 30-bit position mapping, and ø15 mm blind hollow-shaft fit. This model should not be treated as the same case as a solid-shaft EtherNet/IP encoder. The network behavior may look normal, while the controller still receives the wrong position, velocity, preset response, or device identity if the original parameter set and hollow-shaft mounting are not reproduced.

The OCD-EEC1B-1416-B150-PCM is a POSITAL IXARC multiturn absolute encoder with EtherNet/IP interface, CIP profile, optical sensing, binary code, 16-bit singleturn resolution, 14-bit multiturn resolution, mechanical multiturn gearing without battery, steel housing, ø58 mm blind hollow flange, and ø15 mm blind hollow shaft with 30 mm depth.

The first failure boundary is EtherNet/IP parameter agreement. This encoder supports resolution, velocity time base and filter, preset, counting direction, parameter control priority, IP address, DLR, velocity, acceleration, temperature values, and diagnostic bits. If these settings are not copied from the original installation, the encoder may be visible on the network while the axis value or velocity feedback is wrong.

This replacement fails when the EtherNet/IP device is online, but the PLC reads the wrong multiturn position because 16-bit singleturn mapping, 14-bit multiturn range, preset, counting direction, IP address, or velocity filter settings do not match the original encoder. That is a network-parameter failure, not an optical sensing failure.

The second boundary is DLR and M12 mapping. The encoder uses D-coded Ethernet connectors and an A-coded power connector. Tx/Rx pairs, 10–30 VDC supply, GND, shield, and ring topology must be verified before startup. A connector may fit mechanically while the Ethernet ring or device identity remains wrong.

Mechanically, the ø15 mm blind hollow shaft requires clean seating and controlled misalignment. Static and dynamic axial/radial misalignment limits should be treated as installation boundaries, not adjustment room. IP65 shaft and housing protection do not correct poor shaft fit, clamping ring error, or radial connector cable strain.

The replacement decision should first confirm EtherNet/IP CIP compatibility, IP address strategy, DLR topology, M12 Tx/Rx mapping, 10–30 VDC supply, 16-bit singleturn and 14-bit multiturn resolution, preset value, counting direction, velocity settings, diagnostic bits, ø15 mm blind hollow-shaft fit, clamping ring condition, misalignment limits, and shield grounding. EncoderWorks treats OCD-EEC1B-1416-B150-PCM as an industrial encoder custom compatible solution where EtherNet/IP parameter agreement and hollow-shaft mechanics decide field reliability.

Typical production lead time: 15 working days.
