UCD-DPC1B-1216-HCTS-H3P Profibus Multi-Turn Encoder, 12 mm Hollow Shaft

We developed a custom solution for model UCD-DPC1B-1216-HCTS-H3P. Selected when multi-turn absolute feedback is required via Profibus, using a 58 mm blind hollow structure with 12 mm shaft, while avoiding battery-based turn counting and gear-based multi-turn wear points. Typical production lead time: 15 working days. The referenced configuration is a Profibus DPV0/DPV1/DPV2 Class 2 version with magnetic sensing, 16-bit single-turn resolution, 12-bit multi-turn resolution, and a self-powered magnetic pulse counter.

Key Specifications

• Interface: Profibus DPV0 / DPV1 / DPV2 Class 2
• Resolution: 16-bit single-turn + 12-bit multi-turn
• Code: binary
• Multi-turn: self-powered magnetic counter, no battery, no gear train
• Supply: 10–30 VDC
• Protection: IP66/IP67
• Structure: 58 mm blind hollow, 12 mm shaft, 28 mm depth
• Speed: up to 3000 rpm

Decision Snapshot

• Best for: Profibus absolute positioning systems needing battery-free multi-turn retention
• Key fit: 12 mm hollow shaft, 58 mm blind hollow flange, 28 mm insertion depth
• Avoid if: the system only needs incremental pulses or is standardized on another bus architecture; that is an engineering fit judgment based on the published Profibus communication structure and bus-side connection layout.

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 value: configurable Profibus communication with battery-free multi-turn retention.
Primary commissioning risk: incorrect node addressing or termination switching. That conclusion is grounded in the listed address-selection switch, termination-switch hardware, and separate bus-in / bus-out routing.

Mechanical & Installation Focus

• Housing: steel with corrosion-protective coating
• Flange: 58 mm blind hollow, aluminum
• Shaft: 12 mm hollow, 28 mm depth
• Misalignment limits: static ±0.3 mm / ±0.5 mm, dynamic ±0.1 mm / ±0.2 mm

Primary mechanical constraint: blind hollow installation quality.
Best practice: control shaft tolerance, insertion depth, and alignment stability together, not bore size alone. That recommendation follows from the listed misalignment limits and the blind-hollow shaft geometry.

Wiring & Bus Topology

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

Primary commissioning issue: bus topology errors.
Check sequence: address → termination → bus continuity → power. This is an engineering check order derived from the published connection arrangement and switch-based setup method.

Integration & Compatibility

• Designed for Profibus absolute encoder systems with configurable node and scaling functions
• Matches 58 mm blind hollow installations with 12 mm shaft
• Suitable for multi-turn feedback where battery-free retention is preferred
• Not suitable for incremental-only systems or non-Profibus architectures; this is a selection conclusion based on the listed interface and wiring structure.

Lead Time

Typical production lead time: 15 working days. Custom adaptation can be developed around shaft fit, cable entry layout, and bus commissioning requirements.
