We developed a custom solution for model OCD-DPC1B-1212-B06S-H3P. Selected when multi-turn absolute feedback is required via Profibus, using a 58 mm blind hollow structure with 6 mm shaft, without battery replacement in long-cycle positioning systems. Typical production lead time: 15 working days.
Key Specifications
- Interface: Profibus DPV0 / DPV1 / DPV2 Class 2
- Resolution: 12-bit single-turn + 12-bit multi-turn
- Code: Binary
- Multi-turn: mechanical gear train, no battery
- Supply: 10–30 VDC
- Protection: IP66/IP67
- Structure: 58 mm blind hollow, 6 mm shaft, 30 mm depth
- Connection: radial, 3 cable glands
- Speed: up to 3000 rpm
- Sensing: optical
Decision Snapshot
- Best for: Profibus multi-turn positioning systems using compact blind hollow installation
- Key fit: 6 mm hollow shaft, 58 mm blind hollow flange, 30 mm insertion depth
- Avoid if: the system only needs incremental feedback or is built around another motion-bus architecture

Bus Configuration & Communication
- Interface class: Profibus Class 2
- Transmission rate: up to 12 Mbaud
- Cycle time: ≥ 1 ms
- Functions: resolution, scaling, speed filter, preset, direction, limit switch, node number, teach mode, diagnostics
Primary integration risk: incorrect node addressing or termination-switch setup.
Best practice: confirm address setting, termination status, and bus continuity before power-up.
This configuration is selected when the controller already depends on Profibus telegram exchange and the project requires direct multi-turn retention without battery maintenance.
Mechanical & Installation Focus
- Housing: steel with corrosion-protective coating
- Flange: blind hollow, 58 mm
- Shaft: 6 mm hollow, 30 mm depth
- Misalignment limits: static ±0.3 mm / ±0.5 mm, dynamic ±0.1 mm / ±0.2 mm
- Speed capability: 3000 rpm
Primary mechanical constraint: blind hollow installation quality.
Best practice: control shaft tolerance, insertion depth, and alignment stability together, not bore size alone.
On a 6 mm hollow shaft, the installation margin is smaller than on larger bores, so mounting precision has a stronger effect on running stability and service life.
Wiring & Bus Topology
- Connection: radial, 3 cable glands
- Signals: Bus line A / B, power supply, GND for bus in and bus out
Primary commissioning issue: bus topology errors rather than sensing stability.
Check sequence: address → termination → bus continuity → power.
Most startup faults on this structure come from bus-side setup, not encoder sensing.
Integration & Compatibility
- Designed for Profibus absolute encoder systems
- Matches 58 mm blind hollow installations with 6 mm shaft
- Suitable for multi-turn feedback where battery-free retention is required
- Not suitable for incremental-only systems or non-Profibus architectures
Lead Time
Typical production lead time: 15 working days. Custom adaptation can be developed around shaft fit, connection-box layout, and bus commissioning requirements.
