OCD-DPC1B-0016-B080-H72 Profibus Absolute Encoder, 16-bit

We developed a custom solution for model OCD-DPC1B-0016-B080-H72. Selected when single-turn absolute feedback is required via Profibus, using a 58 mm blind hollow structure with 8 mm shaft, without adding multi-turn complexity or battery-based retention. Typical production lead time: 15 working days. The referenced configuration uses Profibus DPV0 / DPV1 / DPV2 Class 2, optical sensing, 16-bit single-turn resolution, binary code, 10–30 VDC supply, and three radial M12 connectors.

Key Specifications

• Interface: Profibus DPV0 / DPV1 / DPV2 Class 2
• Resolution: 16-bit
• Code: Binary
• Supply: 10–30 VDC
• Protection: IP65
• Structure: 58 mm blind hollow, 8 mm shaft, 30 mm depth
• Connection: radial 3 × M12
• Speed: up to 12000 rpm
• Sensing: optical

Decision Snapshot

• Best for: Profibus single-turn absolute positioning with compact blind-hollow installation
• Key fit: 16-bit
• Avoid if: the system requires multi-turn tracking or runs on a non-Profibus motion architecture, because this model is explicitly single-turn and built around Profibus Class 2 communication with M12 bus topology.

Bus Configuration & Communication

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

Primary integration value: bus-based absolute transmission avoids multi-line parallel mapping.
Primary risk: address duplication, termination-switch errors, or bus continuity faults.
Best practice is address → termination → bus continuity → power, because this hardware includes switch-based addressing and dedicated bus in/out connections.

Mechanical & Installation Focus

This version uses a steel housing with corrosion-protective coating, aluminum blind-hollow flange, 8 mm shaft diameter, and 30 mm hollow depth. Maximum speed is 12000 rpm, with listed static/dynamic misalignment limits of ±0.3/±0.5 mm and ±0.1/±0.2 mm.

Primary mechanical constraint: blind-hollow alignment at high shaft speed.
Primary installation value: compact shaft size with high-speed capability.
At 12000 rpm, mounting quality matters more than nominal flange size. If shaft tolerance, insertion depth, and alignment are not controlled together, the first symptoms will usually be vibration, wear, and unstable field performance rather than instant failure. That is an engineering judgment supported by the published speed and misalignment data.

Wiring & Bus Topology

The electrical connection uses three radial M12 connectors: one 4-pin A-coded male and two 5-pin B-coded connectors for bus in and bus out. The published connection plan assigns Power Supply and GND separately from Bus line A / B paths.

Primary commissioning issue: bus topology setup, not sensing stability.
Most startup problems on this structure come from wiring or switch configuration rather than from the encoder core itself.

Integration & Compatibility

• Designed for Profibus absolute encoder systems
• Matches 58 mm blind hollow installations with 8 mm shaft
• Suitable for single-turn feedback where compact hollow-shaft mounting 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, connector layout, and bus commissioning requirements.
