We have developed a custom solution for model OCD-PPA1G-0016-B150-CRW, based on a compact 58 mm blind hollow-shaft platform with a Ø15 mm shaft bore, parallel push-pull singleturn output, and a radial cable outlet for cleaner side-entry routing. This configuration is intended for control systems that still use direct bit-level position acquisition rather than serial communication, while requiring hollow-shaft mounting for simplified mechanical integration. The encoder provides 16-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 primarily on wiring accuracy across multiple conductors rather 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 16, 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 minimum bending radius of 150 mm should be respected from the start. In compact cabinets or side-entry routing layouts, cable stress and forced bend direction are a more common source of long-term instability than the sensing element itself. Because this is a Ø15 mm blind hollow-shaft structure, installation quality also depends 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 practice, radial cable versions often solve routing conflicts better than axial cable versions, but 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 control systems that still rely on direct parallel absolute inputs instead of SSI or fieldbus communication. Its main practical value lies in combining hollow-shaft mounting, 16-bit singleturn resolution, and a radial cable exit that can simplify wiring organization where rear cable clearance is limited.
Compared with SSI or industrial Ethernet encoders, this model reduces protocol complexity but increases the importance of cable organization and I/O discipline. In practice, it is selected when the control architecture already supports parallel position inputs and where a Ø15 mm blind hollow-shaft arrangement is mechanically more suitable than a solid-shaft coupling. It is less suitable for long, noise-prone cable routes or for systems where minimizing conductor count is more important than keeping direct bit-level logic.

Technical Summary
The engineering value of OCD-PPA1G-0016-B150-CRW lies in its combination of a compact 58 mm hollow-shaft structure, 16-bit singleturn absolute output, and a radial parallel push-pull connection that fits restricted wiring layouts better than rear-exit designs. 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.
