OCD-PPA1G-1210-B150-CRW Parallel Absolute Encoder, 10-bit

We developed a custom solution for model OCD-PPA1G-1210-B150-CRW. Selected when multi-turn absolute feedback is required through a parallel push-pull interface, using a 58 mm blind hollow structure with 15 mm shaft, without changing an existing parallel-control architecture. Typical production lead time: 15 working days. The referenced configuration combines 10-bit single-turn resolution, 12-bit multi-turn resolution, Gray code, and a mechanical gear train without battery.

Key Specifications

• Interface: parallel push-pull
• Resolution: 10-bit single-turn + 12-bit multi-turn
• Code: Gray
• Multi-turn: mechanical gear train, no battery
• Supply: 10–30 VDC
• Protection: IP65 shaft side, IP65 housing
• Structure: 58 mm blind hollow, 15 mm shaft, 30 mm depth
• Cable: 1 m radial PVC
• Speed: up to 12000 rpm

Decision Snapshot

• Best for: parallel absolute retrofit systems needing multi-turn retention
• Key fit: 10-bit
• Avoid if: the system is based on fieldbus communication or only requires incremental feedback, because the published interface and 22-bit direct signal map point to a classic parallel architecture rather than bus-based data exchange.

Signal & Output Architecture

The connection plan provides Bit 1 through Bit 22 plus Latch, DIR, Power Supply, and GND. That means position is read directly by hardware-level parallel inputs rather than by protocol parsing.

Primary integration value: direct multi-turn absolute data without bus setup.
Primary limitation: the controller side must handle full bit mapping, so wiring quality and logic assignment matter more than in networked encoder systems. That is an engineering conclusion grounded in the published parallel signal structure.

Mechanical & Installation Focus

This version uses a 15 mm blind hollow shaft with 30 mm insertion depth and published static/dynamic misalignment limits of ±0.3/±0.5 mm and ±0.1/±0.2 mm. With maximum mechanical speed up to 12000 rpm, mounting quality matters more than flange size. Poor shaft fit will show up first as vibration, bearing stress, and unstable field behavior.

Wiring & Installation

The 1 m radial PVC cable uses AWG26 conductors, 7.1 mm cable diameter, and minimum bend radius of 46 mm fixed / 61 mm flexing. Primary commissioning risk remains controller-side bit mapping. Practical startup order is bit sequence → Latch logic → DIR logic → power/GND reference.

Integration & Compatibility

• Designed for parallel absolute encoder systems
• Matches 58 mm blind hollow installations with 15 mm shaft
• Suitable for multi-turn position feedback without battery replacement
• Not suitable for bus-based control structures or simple incremental feedback use cases

Lead Time

Typical production lead time: 15 working days. Custom adaptation can be developed around shaft fit, cable routing, signal assignment, and installation requirements.
