OCD-EEC1B-1416-SA10-PCM EtherNet/IP DLR and Synchro Shaft Fit

OCD-EEC1B-1416-SA10-PCM can be supported by EncoderWorks with a custom compatible replacement focused on EtherNet/IP DLR continuity, 30-bit position mapping, and ø6 mm synchro-flange shaft alignment. This model should not be treated as a simple absolute encoder swap. The main field risk is that the encoder powers up on the network, but the controller does not receive the same CIP profile behavior, IP address, preset value, velocity data, or mechanical coupling stability as the original unit.

The OCD-EEC1B-1416-SA10-PCM is a POSITAL IXARC multiturn absolute encoder with EtherNet/IP interface, CIP profile, 100 Mbit transmission rate, optical sensing, 16-bit singleturn resolution, 14-bit multiturn resolution, binary code, mechanical gearing without battery, and steel housing with ø58 mm synchro flange. It uses a ø6 mm solid double-flat shaft with 10 mm length, radial connection orientation, and M12 Ethernet/power connectors.

The first failure boundary is EtherNet/IP setup. This encoder supports programming functions such as resolution, velocity time base and filter, preset, counting direction, parameter control priority, and IP address. If these parameters are not copied, the PLC may establish communication while the position value, velocity value, or direction behavior no longer matches the machine logic.

This replacement fails when the EtherNet/IP device is visible, but the axis reports the wrong position or velocity because IP address handling, preset, resolution, counting direction, or velocity filter settings were not reproduced from the original encoder. That is a network-parameter failure, not a sensor hardware fault.

The second boundary is DLR and connector continuity. The model uses D-coded M12 Ethernet connectors and an A-coded power connector, with Tx/Rx pairs separated in the connection plan. If DLR ring wiring, Tx/Rx assignment, or power/GND mapping is wrong, the machine may lose one encoder or disturb the network segment. Connector fit alone is not enough.

Mechanically, the ø6 mm synchro-flange shaft needs accurate coupling alignment. The data lists axial 40 N and radial 110 N shaft-load limits, but these should be treated as boundaries, not installation preload. Coupling eccentricity can look like communication noise when it is actually shaft-load instability.

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, ø6 mm shaft fit, synchro-flange centering, and shield grounding. EncoderWorks treats OCD-EEC1B-1416-SA10-PCM as an industrial encoder custom compatible solution where network parameter agreement and synchro-flange mechanics decide field reliability.

Typical production lead time: 15 working days.
