UCD-DPC1B-1216-HBS0-H3P Profibus Multi-Turn Encoder, 11 mm Hollow Shaft

We developed a custom solution for model UCD-DPC1B-1216-HBS0-H3P. Selected when multi-turn absolute feedback is required via Profibus, using a 58 mm blind hollow structure with 11 mm shaft, without battery-based turn counting. Typical production lead time: 15 working days.

Key Specifications

• Interface: Profibus DP (DPV0 / DPV1 / DPV2 Class 2)
• Resolution: 16-bit single-turn + 12-bit multi-turn (binary)
• Multi-turn: self-powered magnetic counter, no battery, no gear train
• Supply: 10–30 VDC
• Protection: IP65 shaft side, IP66/IP67 housing
• Structure: 58 mm blind hollow, 11 mm shaft, 28 mm depth
• Speed: up to 12000 rpm

Decision Snapshot

• Best for: Profibus-based distributed absolute positioning systems
• Key fit: 11 mm hollow shaft with 58 mm flange, 28 mm insertion depth
• Avoid if: system requires incremental output or non-Profibus communication

Bus Configuration & Communication

• Interface class: Profibus Class 2 with configurable node and scaling
• Cycle time: ≥1 ms
• Transmission rate: up to 12 Mbaud
• Functions: preset, scaling, direction, node setting, diagnostics

Primary integration risk: incorrect node addressing or termination setting.
Best practice: confirm bus topology and address allocation before power-up.

Battery-free multi-turn retention removes maintenance dependency. This is a selection advantage in long-cycle systems where access is limited.

Mechanical & Installation Focus

• Bore: 11 mm, depth 28 mm
• Housing: corrosion-protected steel, stainless shaft
• Speed capability: 12000 rpm

Primary mechanical risk: misalignment under blind hollow installation.
Key constraint: shaft tolerance and insertion depth must be controlled, not just diameter.

High-speed operation increases sensitivity to eccentric mounting. Alignment should be treated as a first-step condition, not a final adjustment.

Wiring & Bus Topology

• Radial connection box with bus-in / bus-out routing
• Signals: Bus A, Bus B, power supply, GND
• Addressing: manual setting (0–99)
• Termination: integrated switch

Primary commissioning issue: incorrect termination or bus continuity.
Check sequence: address → termination → bus continuity → power.

Integration & Compatibility

• Designed for Profibus absolute encoder systems with distributed control
• Matches 58 mm blind hollow installation, 11 mm shaft applications
• Suitable for multi-turn positioning without battery maintenance
• Not suitable for incremental systems or non-Profibus architectures

Lead Time

Typical production lead time: 15 working days. Custom adaptation available for shaft fit, connection layout, and node configuration.
