We have developed a custom solution for model OCD-EEC1B-1216-B10A-PSM, based on a compact 58 mm blind hollow-shaft platform with Ø10 mm shaft bore and EtherNet/IP communication for direct network-level integration. This configuration is intended for systems that require multiturn absolute position feedback inside an industrial Ethernet architecture, while also needing shaft-mounted installation in a limited mechanical envelope. The platform uses 16-bit singleturn + 12-bit multiturn resolution with optical sensing and mechanical gear-based multiturn detection. Typical production lead time: 15 working days.
Technical Key Parameters
- Interface: EtherNet/IP
- Resolution: 28 bit (16 bit singleturn + 12 bit multiturn)
- Mounting: Ø58 mm blind hollow shaft
- Shaft type: Ø10 mm blind hollow shaft, 30 mm depth
- Supply voltage: 10–30 VDC

The configuration reflects a compact hollow-shaft encoder structure with radial M12 network connection and integrated switch-oriented Ethernet layout.
Wiring and Installation Notes
This model uses an EtherNet/IP interface with 100 Mbit communication, so integration stability depends more on network structure than on signal wiring. In practice, delayed updates or unstable diagnostics are more often caused by addressing conflicts, switch behavior, or cable-side EMC problems than by the encoder itself. The platform supports IP address setting, parameter control priority, velocity filtering, preset, and counting direction, so stable communication does not automatically mean correct position behavior. During commissioning, IP configuration and controller-side data mapping should be confirmed before scaling or preset logic is adjusted.
The electrical layout uses three M12 connectors with separate Ethernet and power allocation, including Tx/Rx pairs on the D-coded ports and power/GND on the A-coded port. That arrangement is practical for organized field wiring, but it also makes connector-side assignment a common startup mistake when installation is rushed. Mechanically, the Ø10 mm blind hollow shaft should be mounted without excessive clamping force or radial preload. The published axial and radial offset limits are relatively tight, so in real installations shaft seating and alignment are usually a more common long-term issue than network failure, especially when cable routing is done before the shaft is fully aligned.
Application and Integration Notes
This configuration is typically used in EtherNet/IP-based automation systems, distributed control architectures, and compact shaft-mounted motion modules where absolute multiturn feedback needs to be integrated directly into the network layer. Its practical value lies in combining multiturn absolute position, industrial Ethernet communication, and blind hollow-shaft mounting in one compact platform.
Compared with SSI or parallel interfaces, this model reduces controller-side signal interpretation work because position values and diagnostics are handled through the Ethernet architecture. Compared with larger networked encoders, it is better suited where a 58 mm housing and Ø10 mm hollow shaft are mechanically more appropriate. In practice, this type of encoder is selected when direct network integration is necessary, but a larger bus encoder would add unnecessary mechanical size.

Technical Summary
The engineering value of OCD-EEC1B-1216-B10A-PSM lies in its combination of a compact 58 mm hollow-shaft structure, multiturn EtherNet/IP feedback, and direct network-level integration. It is best suited for installations where absolute position and diagnostics need to be handled inside the Ethernet architecture, but the mechanical package still has to remain compact. In practical applications, this type of encoder is selected when a simpler point-to-point interface would reduce integration flexibility, while a larger networked encoder would add unnecessary mechanical bulk.
