UCD-DPC1B-0016-HFS0-H3P Profibus Single-Turn Encoder, 15 mm Hollow Shaft

We developed a custom solution for model UCD-DPC1B-0016-HFS0-H3P. Selected when single-turn absolute feedback is required via Profibus, using a 58 mm blind hollow structure with 15 mm shaft, without adding multi-turn retention or battery-based counting. Typical production lead time: 15 working days.

Key Specifications

• Interface: Profibus DPV0 / DPV1 / DPV2 Class 2
• Resolution: 16-bit single-turn
• Code: Binary
• Supply: 10–30 VDC
• Protection: IP65 shaft side, IP66/IP67 housing
• Structure: 58 mm blind hollow, 15 mm shaft, 28 mm depth

Decision Snapshot

• Best for: Profibus single-turn absolute positioning with blind hollow installation
• Key fit: 15 mm hollow shaft, 58 mm blind hollow flange, 28 mm insertion depth
• Avoid if: the system requires multi-turn retention, incremental-only feedback, or a non-Profibus 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 structure is selected when the control side already depends on Profibus telegram exchange rather than parallel bit mapping or analog scaling.

Mechanical & Installation Focus

• Housing: steel with corrosion-protective coating
• Flange: aluminum, 58 mm blind hollow
• Shaft: 15 mm hollow, 28 mm depth
• Misalignment limits: static ±0.3 mm / ±0.5 mm, dynamic ±0.1 mm / ±0.2 mm
• Speed capability: 12000 rpm

Primary mechanical constraint: blind hollow installation quality.
Best practice: control shaft tolerance, insertion depth, and alignment stability together, not bore size alone.
At this speed level, mounting quality has more impact on long-term stability than the nominal shaft diameter itself.

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 15 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, connection-box layout, and bus commissioning requirements.
