We have developed a custom solution for model OCD-PPA1G-0010-B11S-CRW, built around a compact 58 mm blind hollow-shaft platform with a Ø11 mm shaft bore, parallel push-pull singleturn output, and a radial cable outlet for side-entry wiring. This configuration is intended for systems that still acquire position through direct bit-level inputs rather than SSI or fieldbus communication, while requiring hollow-shaft mounting to simplify mechanical installation. The encoder provides 10-bit singleturn absolute feedback with Gray-code output and cable-side direction setting. Typical production lead time: 15 working days.

The configuration reflects a compact hollow-shaft encoder structure with radial cable outlet and direct parallel bit output for controller-side 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 10, 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 mechanical installation error, so the DIR function should be checked first whenever the count direction appears reversed.
The encoder uses a 1 m radial PVC cable, and the specified bending radius should be respected from the start. In compact cabinets or side-entry routing layouts, cable stress and forced bends near the housing are a more common source of long-term instability than the sensing element itself. Because this is a Ø11 mm blind hollow-shaft structure, installation quality also depends heavily on correct shaft seating and controlled clamping. Excessive radial stress, uneven support, or over-tight fastening can reduce bearing life and affect signal consistency. In practical installations, radial cable versions solve routing conflicts better than axial versions only when enough side clearance is reserved for cable exit and bending.
Application and Integration Notes
This configuration is typically used in compact rotary assemblies, shaft-mounted automation modules, and controller architectures that still rely on direct parallel absolute inputs instead of serial communication. Its main practical value lies in combining hollow-shaft mounting with 10-bit absolute position output, which avoids protocol handling while still giving the controller a direct position word immediately after power-up.
Compared with SSI or fieldbus encoders, this model reduces communication complexity but increases the importance of cable organization and I/O discipline. In practice, it is selected when the control hardware already supports parallel position acquisition and where an Ø11 mm blind hollow-shaft arrangement fits the mechanical layout better than a solid-shaft coupling. 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-0010-B11S-CRW lies in its combination of a compact 58 mm hollow-shaft structure, 10-bit singleturn absolute output, and a direct parallel push-pull interface on a simple electrical architecture. It is best suited for shaft-mounted systems where the controller already works with parallel position inputs and where serial communication would add unnecessary integration overhead. In practical applications, the main success factors are correct bit assignment, stable direction logic, controlled side-entry cable routing, and careful hollow-shaft installation.
