Confirming the installed interface for REF-H50
Pepperl+Fuchs REF-H50 is a photoelectric reflector used to return light to a compatible retroreflective sensor. This entry identifies the complete REF-H50 designation and shows the technical data that can be used as a starting point. The shared main image is a Pepperl+Fuchs category reference montage, not an exact photograph of REF-H50. Final selection still requires the fitted label, the latest manufacturer record and the actual site drawing.

|---|---|
| Exact model | REF-H50 |
| Product role | photoelectric reflector |
| Part | Passive reflector |
| Interface | Optical; no electrical supply |
| System | Match the photoelectric sensor |
| Mounting | Check installed bracket and surface |
| Variant check | Confirm the complete designation and current manufacturer documentation before replacement. |
Installation record
For a replacement REF-H50, compare the full printed code character by character. Confirm supply, I/O direction, signal type, terminal or plug pinout, operating environment and mechanical clearances. If the circuit has functional-safety or hazardous-area requirements, obtain the exact approval documents for REF-H50; the visual similarity of another code is not a valid substitute. Include mating heads, reflectors, boards, cables and licences as separate line items where needed.
Process role
The job of REF-H50 is to return light to a compatible retroreflective sensor. Define its boundary in the real installation: what connects upstream, what response is required downstream, how it is powered and how it is mounted. A model that looks like REF-H50 may not provide the same circuitry or approvals. Capture the present configuration before removal, including any addresses, calibration, scaling, taught limits or software settings.
Test record
At commissioning, Confirm reflector size, alignment and the sensor's specified range. Test REF-H50 in the assembled system using a known input or mechanical condition, then read the corresponding output and controller response. Repeat at the low and high ends of the real operating window. A status LED alone cannot prove that REF-H50 has the correct settings, connected accessory or alarm action. Keep the measured values and any deviations in the maintenance record.
Order record
An RFQ for REF-H50 should quote the complete designation, required quantity, installed controller or host, connection style, certification need and the intended operating environment. Request confirmation for any alternate suffix. Related-looking models are indexed below to help identify inventory, but technical table values on this page apply only to the named REF-H50 variant where verified. Each other complete code needs its own specification review.
Related-looking model strings
These designations visually resemble REF-H50; they can still have different functions, ratings, interfaces and approvals. Verify each complete code independently before ordering or substitution.

Close-out
After the handover of REF-H50, archive the exact label, configuration backup, drawings and test result. If the process or host changes later, redo the relevant match and acceptance checks for REF-H50. Do not treat the product montage or the related-code index as a wiring diagram or a declaration of interchangeability.
Ordering-number and related-reference check
These verified Pepperl+Fuchs references help locate purchasing records. Some identify a different product or accessory, not a replacement for the main model. Confirm the complete type, ratings and approval before ordering.
