UCD-DPC1B-1213-HTT0-H3P Profibus Multi-Turn Encoder, 9.52 mm Hollow Shaft

We developed a custom solution for model UCD-DPC1B-1213-HTT0-H3P. Selected when multi-turn absolute feedback is required via Profibus, using a 58 mm blind hollow structure with a 9.52 mm (3/8") shaft, without battery-based turn counting. Typical production lead time: 15 working days. The referenced configuration uses Profibus DPV0 / DPV1 / DPV2 Class 2, magnetic sensing, 13-bit single-turn resolution, 12-bit multi-turn resolution, and a self-powered magnetic pulse counter without battery or gear train.

Key Specifications

• Interface: Profibus DPV0 / DPV1 / DPV2 Class 2
• Resolution: 13-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: IP65 shaft side, IP66/IP67 housing
• Structure: 58 mm blind hollow, 9.52 mm shaft, 28 mm depth
• Speed: up to 12000 rpm

Decision Snapshot

• Best for: Profibus absolute positioning systems needing battery-free multi-turn retention at higher shaft speed
• Key fit: 9.52 mm hollow shaft, 58 mm blind hollow flange, 28 mm insertion depth
• Avoid if: the system only needs incremental feedback or already uses another motion-bus standard; that follows from the listed Profibus-specific interface and communication structure.

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. That recommendation is supported by the listed address-selection switch and termination-switch hardware.

Mechanical & Installation Focus

• Housing: steel with corrosion-protective coating
• Flange: aluminum, 58 mm blind hollow
• Shaft: 9.52 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 alignment quality at elevated shaft speed. Best practice: control shaft tolerance, insertion depth, and alignment stability together, not bore size alone. On this model, the higher speed rating increases the cost of poor alignment, so mounting quality should be treated as a first-step condition rather than a final correction. This is an engineering judgment based on the published speed limit and misalignment limits.

Wiring & Bus Topology

• Connection: radial connection box
• Signals: Bus line A / B, power supply, GND
• Setup: address selection switch 0–99 and termination resistor DIP switch

Primary commissioning issue: bus topology and switch setup. Check sequence: address → termination → bus continuity → power. That order follows from the published connection-box arrangement and Profibus wiring method.

Integration & Compatibility

• Designed for Profibus absolute encoder systems with configurable node and scaling functions
• Matches 58 mm blind hollow installations with 9.52 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, connection-box layout, and bus commissioning requirements.
