OCD-DPC1B-0012-B14V-H3P Profibus Absolute Encoder, 12-bit

We developed a custom solution for model OCD-DPC1B-0012-B14V-H3P. Selected when single-turn absolute feedback is required via Profibus, using a 58 mm blind hollow structure with 14 mm shaft, without adding multi-turn complexity or battery-based retention. Typical production lead time: 15 working days. The referenced configuration is an optical Profibus version with 12-bit single-turn resolution, binary code, 10–30 VDC supply, and a stainless-steel blind-hollow mechanical package.

Key Specifications

• Interface: Profibus DPV0 / DPV1 / DPV2 Class 2
• Resolution: 12-bit
• Code: Binary
• Supply: 10–30 VDC
• Protection: IP66/IP67 shaft side and housing
• Structure: 58 mm blind hollow, 14 mm shaft, 30 mm depth
• Housing: stainless steel V2A
• Connection: radial, 3 cable glands
• Speed: up to 3000 rpm
• Sensing: optical

Decision Snapshot

• Best for: Profibus single-turn absolute positioning with stainless blind-hollow construction
• Key fit: 12-bit
• Avoid if: the system requires multi-turn retention or uses a non-Profibus motion architecture, because this model is explicitly single-turn and built around Profibus Class 2 communication with connection-box addressing and termination switching.

Bus Configuration & Communication

The interface is Profibus DPV0 / DPV1 / DPV2 Class 2 with optical isolation on the data interface, transmission up to 12 Mbaud, cycle time from 1 ms, and programmable functions including resolution, scaling, speed filter, preset, counting direction, limit switch, node number, teach mode, and diagnostics. Manual functions include node address selection 0–99 and termination resistor DIP switching in the connection box.

Primary integration value: bus-based single-turn absolute transmission without parallel bit mapping.
Primary risk: address duplication, termination-switch errors, or bus continuity faults.
Best practice is address → termination → bus continuity → power, because this hardware uses switch-based addressing and dedicated bus in/out wiring through a glanded connection box.

Mechanical & Installation Focus

The mechanical package uses stainless steel V2A housing and flange, 14 mm blind hollow shaft, 30 mm insertion depth, and published static/dynamic misalignment limits of ±0.3/±0.5 mm and ±0.1/±0.2 mm. Maximum mechanical speed is 3000 rpm, weight is 1025 g, and friction torque is up to 5 Ncm at 20 °C.

Primary mechanical value: stainless construction for harsher environments.
Primary mechanical constraint: blind-hollow alignment still governs long-term stability. Stainless housing improves durability, but it does not reduce the need for correct shaft tolerance, insertion depth, and alignment quality. That priority is supported by the published misalignment limits and 30 mm hollow-shaft depth.

Wiring & Bus Topology

The electrical connection is radial with 3 cable glands. The connection plan shows Bus line A / B for bus in and bus out, plus Power Supply and GND on both sides of the bus path.

Primary commissioning issue: bus-side setup, not sensing stability.
Most startup problems on this structure come from address, termination, or continuity errors rather than from the encoder core itself. That conclusion follows directly from the published connection-box hardware and line assignment.

Integration & Compatibility

• Designed for Profibus absolute encoder systems
• Matches 58 mm blind hollow installations with 14 mm shaft
• Suitable for single-turn feedback where stainless construction is required
• Not suitable for multi-turn 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.
