We have developed a custom solution for model OCD-DPC1B-1412-B100-H72, built around a compact 58 mm blind hollow-shaft platform with a Ø10 mm shaft bore and Profibus Class 2 communication. This configuration is intended for installations that need multiturn absolute feedback with fieldbus-side parameter handling, while also requiring direct hollow-shaft mounting in a compact mechanical envelope. The platform uses 12-bit singleturn + 14-bit multiturn resolution with optical sensing and mechanical gear-based multiturn detection, combined with a radial 3 × M12 connection layout for organized power and bus routing. Typical production lead time: 15 working days.

The configuration reflects a compact hollow-shaft encoder structure with radial M12 connector layout for separated power, bus in, and bus out routing.
Wiring and Installation Notes
This model uses a Profibus interface with optical isolation, so long-term stability depends more on bus layout discipline than on the encoder body itself. In practice, communication faults are more often caused by address conflicts, inconsistent termination, or connector-side routing errors than by hardware failure. The platform supports manual address selection from 0 to 99 and termination resistor switching, so commissioning should confirm node logic and bus end conditions before scaling, preset, or filter settings are changed. It also supports programmable resolution, transmission ratio, speed filtering, preset, counting direction, limit switch behavior, node number, teach mode, and diagnostics, which is useful in retrofit work but also makes incorrect parameter inheritance a common source of stable communication with incorrect position behavior.
The radial 3 × M12 layout separates power, bus in, and bus out, which helps wiring organization but also makes connector assignment a frequent startup mistake if installation is done too quickly. Mechanically, the Ø10 mm blind hollow shaft simplifies shaft mounting, but alignment and clamping quality still matter. The published axial and radial offset limits are relatively tight, so in practical installations shaft seating and alignment are often a more common long-term issue than electrical mismatch.
Application and Integration Notes
This configuration is typically used in compact Profibus-based motion systems, retrofitted fieldbus axes, and shaft-mounted drive assemblies where multiturn absolute feedback is required but the mechanical package still has to remain compact. Its practical value lies in combining fieldbus-side configurability with blind hollow-shaft mounting, which can reduce coupling adaptation work compared with a solid-shaft version.
Compared with simpler point-to-point interfaces, this model transfers position directly through Profibus and avoids separate signal interpretation at the PLC input level. In practice, it is selected when a compact hollow-shaft package is required, but a simple parallel or incremental structure would remove too much bus-level flexibility.

Technical Summary
The engineering value of OCD-DPC1B-1412-B100-H72 lies in its combination of a compact 58 mm hollow-shaft structure, Profibus multiturn feedback, and a service-friendly 3 × M12 connection layout. It is best suited for installations where the system still benefits from bus-level functions such as addressing, preset, scaling, and diagnostics, but where a larger fieldbus encoder would add unnecessary mechanical size.
