We have developed a custom solution for model OCD-PPA1G-0810-B15S-PRT, built around a compact 58 mm blind hollow-shaft platform with a Ø15 mm shaft bore, parallel push-pull multiturn output, and a connector-based connection structure for direct controller-side integration. This configuration is intended for systems that still acquire position through direct bit-level inputs rather than SSI or fieldbus communication, while requiring multiturn absolute feedback in a hollow-shaft mechanical layout. The platform provides 10-bit singleturn + 8-bit multiturn Gray-code output, making it suitable for control architectures that prefer direct parallel acquisition without protocol-side overhead. Typical production lead time: 15 working days.

The configuration reflects a compact hollow-shaft encoder structure with connector-based output and direct parallel bit transmission 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 concept includes multiple position bits 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.
Because this version uses a connector-based outlet rather than a fixed cable, field wiring quality depends heavily on correct mating, strain control, and clean pin assignment. In practice, connector-based versions simplify service access but make startup errors more likely if pin mapping is assumed rather than verified. Mechanically, the Ø15 mm blind hollow shaft allows direct shaft mounting, but installation quality still depends on correct shaft seating and controlled clamping. Excessive radial stress or uneven support can reduce bearing life and affect signal consistency. In shaft-mounted layouts, clamping quality and alignment usually influence long-term stability more than the sensing element itself.
Application and Integration Notes
This configuration is typically used in shaft-mounted automation modules, compact rotary assemblies, and controller architectures that still rely on direct parallel absolute inputs instead of serial communication. Its main practical value lies in combining multiturn Gray-code output with direct hollow-shaft installation, which avoids protocol handling while still giving the controller direct position information across multiple revolutions.
Compared with SSI or fieldbus encoders, this model reduces communication complexity but increases the importance of I/O discipline and connector-side wiring accuracy. In practice, it is selected when the control hardware already supports parallel position acquisition and where a Ø15 mm blind hollow-shaft arrangement fits the mechanical layout better than a solid-shaft coupling. It is less suitable for long, noise-prone signal paths or for systems where minimizing conductor count matters more than keeping direct controller-side logic.

Technical Summary
The engineering value of OCD-PPA1G-0810-B15S-PRT lies in its combination of a compact 58 mm hollow-shaft structure, multiturn parallel absolute output, and a service-friendly connector-based connection layout. It is best suited for shaft-mounted systems 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, verified connector pin mapping, and careful hollow-shaft installation.
