OCE-EIC1B-1413-E140-HFZ Profinet Multi-Turn Encoder, 14 mm Hollow Shaft

We developed a custom solution for model OCE-EIC1B-1413-E140-HFZ. Selected when multi-turn absolute feedback is required via Profinet in Zone 1 & 21 oil and gas environments, using a 78 mm ATEX blind hollow structure with 14 mm shaft, without battery-based turn counting. Typical production lead time: 15 working days. The referenced configuration uses Profinet with Profidrive Profile 4.x and Encoder Profile 4.0 / 4.1 / 4.2, optical sensing, 13-bit single-turn resolution, 14-bit multi-turn resolution, and a mechanical gear-based multi-turn system without battery.

Key Specifications

• Interface: Profinet
• Profile: Profidrive Profile 4.x, Encoder Profile 4.0 / 4.1 / 4.2
• Resolution: 13-bit single-turn + 14-bit multi-turn
• Code: Binary
• Multi-turn: mechanical gear train, no battery
• Supply: 10–32 VDC
• Protection: IP65 shaft side, IP66/IP67 housing
• Structure: 78 mm ATEX blind hollow, 14 mm shaft, 30 mm depth
• Speed: up to 3000 rpm
• Approval: CE + ATEX Zone 1 & 21 (Oil+Gas)

Decision Snapshot

• Best for: hazardous-area Profinet absolute positioning in oil and gas applications
• Key fit: 14 mm hollow shaft, 78 mm ATEX blind hollow flange, 30 mm insertion depth
• Avoid if: the project only needs incremental feedback or does not require Profinet / hazardous-area compliance; that follows from the listed Ethernet interface, profile stack, and ATEX approval.

Bus Configuration & Communication

• Interface class: Profinet
• Transmission rate: 100 Mbit
• Cycle time: ≥ 125 µs
• Functions: resolution, velocity filter, preset, counting direction, IP address, fractional scaling, encoder parameter control via GSDML or non-volatile memory
• Diagnostics: memory, temperature, synchronization, commissioning, communication, master sign-of-life

Primary integration value: Ethernet-based absolute feedback with profile-level parameter control and detailed diagnostics. Primary integration risk: network configuration errors on IP setup, Rx/Tx pair assignment, or commissioning parameters. This is a structured network encoder, so the commissioning discipline should match the network architecture rather than a basic point-to-point replacement mindset.

Mechanical & Installation Focus

• Housing: aluminum, anodized
• Flange: 78 mm ATEX blind hollow
• Shaft: 14 mm hollow, 30 mm depth
• Load capability: axial 60 N, radial 80 N
• Misalignment limits: static ±0.3 mm / ±0.5 mm, dynamic ±0.1 mm / ±0.2 mm
• Speed capability: 3000 rpm

Primary mechanical constraint: blind hollow alignment quality in a hazardous-area installation. Best practice: control shaft tolerance, insertion depth, and cable bend space together, not flange size alone. The published misalignment limits and sealed connection layout support that installation priority.

Wiring & Bus Topology

• Connection: radial sealed layout
• Signals: GND, Power Supply, Rx-, Tx-, Rx+, Tx+
• Startup time: < 15 s

Primary commissioning issue: Ethernet-side wiring or network setup, not sensing stability. Check sequence: power → Rx/Tx integrity → IP/network setup → profile parameters. That check order follows from the published line assignment and Profinet-specific configuration functions.

Integration & Compatibility

• Designed for Profinet absolute encoder systems in Zone 1 & 21 oil and gas environments
• Matches 78 mm ATEX blind hollow installations with 14 mm shaft
• Suitable for multi-turn feedback where hazardous-area approval and network diagnostics are both required
• Not suitable for incremental-only systems or non-Ethernet architectures; this is a selection conclusion based on the listed interface, approval, and wiring structure.

Lead Time

Typical production lead time: 15 working days. Custom adaptation can be developed around shaft fit, network layout, cable entry, and hazardous-area installation requirements.
