Identifying BF 18-F in the field and confirming its signal path
Pepperl+Fuchs BF 18-F is a M18 sensor mounting flange for holding a cylindrical sensor in a repeatable machine position. The shared product montage is a category reference image rather than a photo of this exact BF 18-F variant. The table places the verified identity and useful selection data at the front; the notes below explain where a maintenance or purchasing team should confirm the installed circuit.
Technical parameters and fit
| Technical item | Verified value / selection note |
|---|---|
| Exact model | BF 18-F |
| Product role | M18 sensor mounting flange |
| Part class | Mechanical mounting flange |
| Intended fit | M18 cylindrical sensor mounting |
| Electrical connection | None; accessory only |
| Selection | Check flange dimensions and sensor housing fit |
| Variant check | Confirm the complete designation and current manufacturer documentation before replacement. |
On-site proof
After BF 18-F is connected, After tightening, confirm sensor alignment and repeatable detection under vibration. Record the input condition and the controller's observed response at both ends of the useful operating range. Also check supply, diagnostics and any line-fault indication. A successful power-on indication alone does not prove that BF 18-F has the correct configuration.
Application path
In this installation, BF 18-F supports holding a cylindrical sensor in a repeatable machine position. Start at the field device or mechanical target, follow the signal through the connection and identify what the host expects. A catalog family resemblance cannot establish output polarity, scaling, hazardous-area approval or interchangeability. The complete BF 18-F code is the procurement reference, while the as-installed drawing is the acceptance reference.
Installation interface
Before fitting BF 18-F, Compare the installed bracket, M18 body and allowable adjustment range. Inspect available cabinet or machine space, cable exit, terminals, environmental limits and nearby equipment. If an old unit has user settings, document them before removal. Confirm the latest nameplate and electrical drawing because BF 18-F variants can share an enclosure while differing in function.
Replacement decision
When purchasing BF 18-F, BF 18-F is a mounting part, not a sensing element; include the sensor separately if needed. Share the full model, site photos and required certificates with the supplier. Any proposed alternative should be checked against the exact connected equipment and signed off before it replaces BF 18-F; a similar-looking code is a search reference, not a declared equivalent.
Other visually related ordering codes
The following designations resemble the BF 18-F naming pattern and are collected here to help buyers locate variants. Their functions, electrical ratings, connections and approvals may differ. The exact BF 18-F technical values above must not be copied onto another suffix without checking its own datasheet.
- BF 22
- BF 5-30
- BF-18
- BF-30
Handover note
Keep the drawing, configured settings, inspection result and purchasing record with BF 18-F. Recheck the current manufacturer datasheet if the duty, mounting, network or approval changes. This closes the BF 18-F selection and commissioning review without treating related codes as interchangeable.
