We have developed a custom solution for model OCD-PPA1G-0812-C10S-CRW, built around a compact 58 mm clamping-flange platform with a Ø10 mm solid shaft and a parallel push-pull multiturn output structure. This configuration is intended for systems that still acquire position through direct bit-level inputs rather than SSI or fieldbus communication, while also requiring multiturn absolute feedback in a compact mechanical package. The platform provides 12-bit singleturn + 8-bit multiturn Gray-code output and a radial cable outlet, making it suitable for control architectures that prefer direct parallel acquisition without adding protocol-side complexity. Typical production lead time: 15 working days.

The configuration reflects a compact shaft-type encoder structure with radial cable outlet and direct parallel bit output for controller-side multiturn position acquisition.
Wiring and Installation Notes
This model uses a parallel push-pull output, so long-term stability depends more on wiring discipline across multiple conductors than on protocol settings. In practice, stable but incorrect position values are more often caused by bit-order mistakes, undefined control lines, or inconsistent ground reference than by encoder failure. The connection plan includes Bit 1 to Bit 20, plus Latch, DIR, Power Supply, and GND, so commissioning should verify signal assignment before controller-side scaling or logic is finalized. On this type of interface, incorrect direction behavior often looks like a counting or gearing problem, so the DIR function should be checked first whenever the position value changes in the wrong sense.
The encoder uses a 1 m radial PVC cable, and the specified minimum bending radius should be respected from the start. In compact cabinets, cable stress and forced bends near the housing are a more common source of long-term instability than the sensing element itself. Mechanically, the Ø10 mm shaft and 20 mm shaft length provide a practical coupling base, but this is still a compact platform with moderate shaft-load capacity rather than a heavy-duty shaft design. Excessive radial preload or forced axial seating can shorten bearing life and degrade signal stability over time. In practical installations, coupling mismatch is usually a more common long-term issue than electronics.
Application and Integration Notes
This configuration is typically used in compact automation systems, positioning units, indexing assemblies, and retrofit control architectures where multiturn absolute feedback is required but the controller still works with direct parallel position inputs. Its practical value lies in combining multiturn Gray-code output with a 10 mm shaft / 58 mm flange mechanical format that remains compact without dropping to a smaller, less stable shaft interface.
Compared with SSI or industrial Ethernet encoders, this model reduces protocol complexity but increases the importance of I/O organization and wiring accuracy. In practice, it is selected when the control hardware already supports direct bit-level acquisition and where a compact shaft-mounted encoder is preferred over a networked or serial alternative. It is less suitable for long, noise-prone cable routes or for systems where minimizing conductor count matters more than keeping simple controller-side logic.

Technical Summary
The engineering value of OCD-PPA1G-0812-C10S-CRW lies in its combination of a compact 58 mm clamping-flange structure, Ø10 mm shaft, and multiturn parallel absolute output on a simple electrical architecture. It is best suited for installations where direct controller-side position acquisition is required across multiple revolutions, but serial communication would add unnecessary integration overhead. In practical applications, the main success factors are correct bit assignment, stable direction logic, controlled radial cable routing, and accurate coupling alignment.
