We have developed a custom solution for model OCF-DPC1B-1213-B06S-H3E, built around a compact 58 mm blind hollow-shaft platform with a Ø6 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 limited mechanical envelope. The platform uses 13-bit singleturn + 12-bit multiturn resolution with optical sensing and mechanical gear-based multiturn detection, combined with a radial Zone 2 & 22 cable-gland connection structure for hazardous-area applications. Typical production lead time: 15 working days.

The configuration reflects a compact hollow-shaft encoder structure with radial hazardous-area cable-gland layout for separated power and bus 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 on this type of encoder 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 when used with the appropriate connection concept, so commissioning should confirm node logic and bus end conditions before scaling or preset functions are touched. 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 projects but also makes parameter inheritance a common source of stable communication with incorrect position behavior.
The connection structure is radial and uses a 3 × cable gland Zone 2+22 arrangement, with separate terminals for bus in, bus out, power, and ground. That layout is useful for organized field wiring, but it also means shield quality, cable preparation, and routing discipline matter more than in compact plug-only versions. Mechanically, the Ø6 mm blind hollow shaft makes installation more sensitive than larger shaft platforms. The published allowable static and dynamic axial/radial offsets are relatively small, so coupling mismatch or uneven shaft seating is usually a more common long-term issue than electrical mismatch. In practical installations, small-shaft hollow-bore versions often fail first through mounting stress, not through sensing problems.
Application and Integration Notes
This configuration is typically used in compact Profibus-based motion systems, hazardous-area installations, and shaft-mounted drive assemblies where multiturn absolute feedback is required but installation space and shaft size remain limited. Its practical value lies in combining fieldbus-side configurability with blind hollow-shaft mounting, which can reduce mechanical adaptation work compared with a solid-shaft encoder and separate coupling arrangement.
Compared with simpler point-to-point interfaces, this model reduces controller-side interpretation work because position is transferred directly through Profibus. Compared with larger hazardous-duty fieldbus encoders, it is better suited to installations where a Ø6 mm shaft bore and 58 mm housing are mechanically more appropriate. In practice, this type of encoder is selected when a compact hazardous-area package is required, but a simple parallel or incremental solution would remove too much bus-level flexibility.

Technical Summary
The engineering value of OCF-DPC1B-1213-B06S-H3E lies in its combination of a compact 58 mm hollow-shaft structure, Profibus multiturn feedback, and a hazardous-area radial cable-gland layout. It is best suited for installations where shaft space is limited but the system still benefits from bus-level functions such as addressing, preset, scaling, and diagnostics. In practical applications, this type of encoder is selected when a simpler interface would reduce integration flexibility, while a larger fieldbus encoder would add unnecessary mechanical size.
