ifm O2D5 Dualis Vision Sensors
Inspect contours, surfaces, presence, position and component features directly at the machine. O2D5 combines industrial 2D image processing with guided Vision Assistant setup for error-proofing and inspection tasks that need more information than a conventional photoelectric sensor can provide.

Inspection capabilities
Move beyond presence sensing to image-based inspection
O2D5 is useful when the question is not only “is an object present?” but “is the right geometry, contour, position or surface condition present?”
Area / feature analysis
Evaluate connected image regions for presence, count or surface-feature inspection.
- Area checks
- Object features
On-sensor evaluation
Use logic blocks in Vision Assistant to combine inspection results before passing information onward.
- Mini-PLC style logic
- Calculated results
Application-specific light
Select RGB-W or infrared illumination and lens angle according to material, contrast and working distance.
- Polarisation on RGB-W variants
- IR for selected surfaces
Applications
O2D5 in the system architecture
Use 2D vision for repeatable, image-based inspection when the relevant feature is visible in the camera image and can be distinguished with suitable lighting and resolution.
Presence & completeness
Confirm that required components, clips, holes or features are present before the next operation.
Contour / surface inspection
Detect contour deviations, filled/open features or defined image regions during production.
Position & orientation
Determine whether a part or feature is located within an acceptable position window.
2D vision technology
A camera, illumination and evaluation logic in one industrial sensor
The O2D5 uses image-based tools rather than a single light spot. Successful applications depend on field of view, pixel resolution, working distance, target contrast, illumination and motion.

Field of viewSelect standard, wide-angle or telephoto optics to match working distance and inspection area.
IlluminationRGB-W versions include a polarisation filter; infrared variants suit selected low-contrast or colour-independent tasks.
Vision AssistantGuided wizards support contour, BLOB and position applications; expert mode provides deeper configuration.
InterfacesVariant selection also depends on the required process/communication interface.
Product selection
Lens, illumination and interface selection
Current O2D5 variants combine three lens angles with RGB-W or infrared illumination and different process-interface options. Use IFM’s field-of-view calculator for final selection.
| Example family | Illumination | Lens | Representative article | Selection note |
|---|---|---|---|---|
| O2D50x | RGB-W + polarisation | 16° / 30° / 10° | O2D500 / 502 / 504 | TCP/IP family; select lens by field of view. |
| O2D52x | Infrared | 16° / 30° / 10° | O2D520 / 522 / 524 | IR route for suitable surfaces / contrast conditions. |
| O2D51x / 53x | RGB-W or IR | 16° / 30° / 10° | O2D510…534 | Alternative process-interface family; confirm PLC/network requirement. |
Technology choice
O2D5 or another IFM vision route?
Do not use O2D5 merely because “a camera is needed”. Match the device to whether the job is 2D inspection, code/text identification or actual 3D geometry.
| Requirement | IFM route | Why |
|---|---|---|
| Contour / surface / presence inspection | O2D5 | Dedicated 2D object recognition and inspection. |
| Code + OCR + identification | O2I / O2U | Identification tools are the primary requirement. |
| Combined inspection + codes via IO-Link | O2U | Newer universal sensor combines O2D/O2I-type functions. |
| Depth, volume, height or 3D geometry | O3D | Time-of-flight depth data, not a 2D image alone. |

Inputs required to size the O2D5 application
A sample image or physical part is useful, but the geometry and inspection tolerance must be defined first.
Inspection taskPresence, contour, area, count, distance between features or orientation.

Field of viewRequired width and height of the inspected area.
