We developed a custom solution for model OCF-DPC1B-0016-B06S-H3E. This configuration is intended for projects that need an absolute Profibus encoder with Zone 2 and 22 approval, 58 mm blind hollow structure, and 6 mm shaft bore. The referenced configuration shows Profibus DPV0/DPV1/DPV2 Class 2, 10–30 VDC supply, 16-bit single-turn optical feedback, IP66/IP67 protection, and CE + ATEX Zone 2 & 22 approval. Typical production lead time: 15 working days.
Technical Key Parameters
The main engineering value of this model is not only the fieldbus interface but the hazardous-area suitability. It supports transmission rate up to 12 Mbaud, opto-isolated Profibus output, and programmable functions including preset, scaling, node setting, direction, and diagnostic mode. The sensing principle is optical, with 16-bit single-turn resolution and listed accuracy of ±0.0220° for 14–16 bit ranges.
Mechanically, it uses a 58 mm blind hollow housing with 30 mm bore depth and 6 mm shaft diameter, plus corrosion-resistant construction and IP66/IP67 enclosure protection. For selection work, the small 6 mm bore is an important anchor point: it is better suited for light compact shafts where maintaining alignment quality matters more than high shaft load margin. The hazardous certification also makes this version more than a normal Profibus replacement; it is a compliance-sensitive solution.

Wiring and Installation Notes
This version uses three cable glands in radial direction and a bus-in / bus-out wiring structure. The connection plan shows Bus line A, Bus line B, Power Supply+, and GND- for both input and output bus routing. In installation, shielding, gland sealing, and enclosure integrity must be handled carefully, because hazardous-area performance depends on the whole assembled condition, not only the encoder body. The blind hollow shaft should be clamped without forcing eccentric load into the bore.
Custom Compatible Encoder Solution
- Custom absolute Profibus solution for Zone 2 / 22 working environments
- Adaptation available for 58 mm blind hollow shaft and 6 mm bore structure
- Support for preset, scaling, node setting, and direction parameter alignment
- Suitable for projects where hazardous-area approval and sealed housing are both required
Lead Time and Custom Development
Typical production lead time: 15 working days.
For hazardous-area retrofits, we can develop the solution according to confirmed shaft size, cable entry method, and bus installation layout.
