OCF-DPC1B-0012-C12V-H3E Profibus Single-Turn Encoder, 12 mm Shaft

We developed a custom solution for model OCF-DPC1B-0012-C12V-H3E. Selected when single-turn absolute feedback is required via Profibus, using a 58 mm clamping flange with 12 mm solid shaft, while meeting Zone 2 & 22 hazardous-area requirements with stainless-steel construction. Typical production lead time: 15 working days. The referenced configuration uses Profibus DPV0 / DPV1 / DPV2 Class 2, optical sensing, 12-bit single-turn resolution, 10–30 VDC supply, and CE + ATEX Zone 2 & 22 approval.

Key Specifications

• Interface: Profibus DPV0 / DPV1 / DPV2 Class 2
• Resolution: 12-bit single-turn
• Code: Binary
• Supply: 10–30 VDC
• Protection: IP66/IP67
• Structure: 58 mm clamping flange, 12 mm solid shaft, 20 mm shaft length
• Housing: stainless steel
• Speed: up to 3000 rpm
• Approval: CE + ATEX Zone 2 & 22

Decision Snapshot

• Best for: hazardous-area Profibus single-turn positioning systems
• Key fit: 12 mm solid shaft, 58 mm clamping flange, stainless housing package
• Avoid if: the system only needs incremental feedback or does not require Profibus / hazardous-area compliance; that follows from the listed bus interface, approval, and connection-box structure.

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-in / bus-out continuity before power-up. That judgment is grounded in the listed address-selection switch, termination DIP switch, and separate bus-in / bus-out wiring plan.

Mechanical & Installation Focus

• Housing: stainless steel V2A
• Flange: stainless 58 mm clamping flange
• Shaft: 12 mm solid, single-flat, 20 mm length
• Load capability: axial 40 N, radial 110 N
• Speed capability: 3000 rpm

Primary mechanical value: stainless construction with Zone 2 & 22 approval. Primary mechanical constraint: coupling quality still matters, because the published bearing-life values change strongly with axial and radial load. This makes the model suitable for harsh environments, but not a license to ignore alignment quality.

Wiring & Bus Topology

• Connection: radial, 3 cable glands for Zone 2+22
• Signals: Bus line A / B, power supply, GND for bus in and bus out

Primary commissioning issue: bus-side setup, not sensing stability. Check sequence: address → termination → bus continuity → power. That sequence follows directly from the published connection-box hardware and line assignment.

Integration & Compatibility

• Designed for Profibus absolute encoder systems in Zone 2 & 22 environments
• Matches 58 mm clamping flange installations with 12 mm solid shaft
• Suitable for single-turn positioning where stainless construction and hazardous-area approval are required
• Not suitable for incremental-only systems or non-Profibus architectures; this is a selection conclusion based on the listed interface, approval, and wiring structure.

Lead Time

Typical production lead time: 15 working days. Custom adaptation can be developed around shaft fit, connection layout, hazardous-area installation, and bus commissioning requirements.
