We developed a custom solution for model UCD-DPC1B-0016-HRY0-H72. Selected when single-turn absolute feedback is required via Profibus, using a 58 mm blind hollow structure with 6.35 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, magnetic 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 shaft side, IP66/IP67 housing
- Structure: 58 mm blind hollow, 6.35 mm shaft, 28 mm depth
- Connection: radial 3 × M12
- Speed: up to 12000 rpm
- Sensing: magnetic
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 retention or uses a non-Profibus motion architecture; the page explicitly describes single-turn Profibus communication with switch-based node addressing and termination.

Encoder structure reference: 58 mm blind hollow flange, 6.35 mm shaft, radial M12 bus connector layout.
Bus Configuration & Communication
This model uses a Profibus Class 2 interface with optical isolation, transmission up to 12 Mbaud, cycle time from 1 ms, and programmable functions including resolution, scaling, preset, direction, node number, and diagnostics.
Primary integration value: bus-based absolute transmission eliminates multi-line parallel mapping.
Primary risk: incorrect node addressing or termination-switch setup. Best practice is address → termination → bus continuity → power, because this configuration depends on a switch-based connection box and fixed bus topology.
Mechanical & Installation Focus
The 6.35 mm blind hollow shaft, 28 mm insertion depth, and listed static/dynamic misalignment limits make mounting precision the key mechanical issue. This is not a forgiving installation. At the published 12000 rpm speed capability, even small alignment errors can turn into vibration, bearing stress, and unstable field performance. That is an engineering judgment grounded in the shaft size, speed rating, and misalignment tolerances.
Wiring & Bus Topology
The device uses three radial M12 connectors: one 4-pin A-coded and two 5-pin B-coded connectors. The bus layout separates power and bus in/out paths, which improves serviceability but makes topology setup non-negotiable. 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 6.35 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.
