OCD-PPA1G-0016-B15S-CAW Parallel Push-Pull Singleturn Absolute Encoder Custom Solution

We have developed a custom solution for model OCD-PPA1G-0016-B15S-CAW, built around a compact 58 mm blind hollow-shaft platform with a Ø15 mm shaft bore, parallel push-pull singleturn output, and an axial cable outlet 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 hollow-shaft mounting to simplify mechanical installation. The encoder provides 16-bit singleturn absolute feedback with Gray-code output and cable-side direction setting. Typical production lead time: 15 working days.

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 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 is supplied with a 1 m axial PVC cable, and the specified minimum bending radius of 150 mm should be respected from the beginning. In compact cabinets, cable stress and forced bends 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 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, hollow-shaft encoders usually tolerate less mounting abuse than users expect, especially when mechanical alignment is done after cable routing instead of before it.

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 16-bit absolute position output, which avoids protocol handling while still giving the controller a full position word immediately after power-up. That makes it useful where the electrical architecture is already built around discrete inputs and where changing to SSI or Ethernet would create unnecessary redesign.

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 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 cable routes or for systems where minimizing conductor count matters more than keeping simple controller-side logic.

Custom Encoder Solution

• Compact 58 mm hollow-shaft structure for direct shaft-mounted installations

• Ø15 mm blind hollow shaft for compact mechanical integration
• Suitable for systems using Latch / DIR logic instead of serial communication

Lead Time and Custom Development

This model is configured based on confirmed hollow-shaft geometry, singleturn resolution, and parallel output integration requirements. Typical production lead time: 15 working days.

Key Technical Data

Technical Summary

The engineering value of OCD-PPA1G-0016-B15S-CAW lies in its combination of a compact 58 mm hollow-shaft structure, 16-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 cable routing, and careful hollow-shaft installation.
