OCD-PPA1G-1212-B100-CRW Parallel Multi-Turn Encoder, 10 mm Hollow Shaft

We developed a custom solution for model OCD-PPA1G-1212-B100-CRW. Selected when multi-turn absolute feedback is required via parallel push-pull output, using a 58 mm blind hollow structure with 10 mm shaft, without changing an existing parallel-control architecture. Typical production lead time: 15 working days. The referenced configuration is an optical multi-turn version with 12-bit single-turn resolution, 12-bit multi-turn resolution, Gray code, a mechanical gear-based multi-turn system without battery, 10–30 VDC supply, and IP65 protection.

Key Specifications

• Interface: parallel push-pull
• Resolution: 12-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, 10 mm shaft, 30 mm depth
• Cable: 1 m radial PVC
• Speed: up to 12000 rpm

Decision Snapshot

• Best for: parallel absolute retrofit systems needing higher-resolution multi-turn position retention
• Key fit: 10 mm hollow shaft, 58 mm blind hollow flange, 30 mm insertion depth
• Avoid if: the system is based on fieldbus communication or only requires incremental feedback; that conclusion follows from the listed parallel interface and direct bit-output structure.

Signal & Output Logic

• Bit 1–24 parallel output
• Includes Latch and DIR control
• Direction configurable via cable or connector setting

Primary integration reason: the controller reads direct multi-turn absolute bit data rather than bus telegrams. Primary limitation: this architecture is efficient for parallel retrofit, but it is not suitable for Profibus, CANopen, EtherCAT, or incremental-only systems. That conclusion follows from the published 24-bit output map and push-pull interface.

Wiring & Installation

• Connection: 1 m radial PVC cable
• Cable: AWG 26, 7.1 mm diameter
• Minimum bend radius: 46 mm fixed, 61 mm flexing

Primary commissioning risk: incorrect controller-side bit mapping on high-bit parallel systems. Primary installation value: the listed 12000 rpm maximum speed makes this version suitable where shaft speed matters more than bus integration. Primary mechanical constraint: blind hollow installation quality. The page also lists static and dynamic misalignment limits, so shaft tolerance, insertion depth, and alignment stability should be controlled together, not bore size alone.

Integration & Compatibility

• Designed for parallel absolute encoder systems
• Matches 58 mm blind hollow installations with 10 mm shaft
• Suitable for multi-turn position feedback without battery replacement
• Not suitable for bus-based control structures or simple incremental feedback use cases; this is a selection conclusion based on the listed interface and output type.

Lead Time

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