Technical identity, constraints and acceptance of PSE4-SL-01
Pepperl+Fuchs PSE4-SL-01 is a safety photoelectric edge used to provide a protective one-beam input with a PSE4 control unit. This entry identifies the complete PSE4-SL-01 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 PSE4-SL-01. Final selection still requires the fitted label, the latest manufacturer record and the actual site drawing.

Decision memo
The job of PSE4-SL-01 is to provide a protective one-beam input with a PSE4 control unit. 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 PSE4-SL-01 may not provide the same circuitry or approvals. Capture the present configuration before removal, including any addresses, calibration, scaling, taught limits or software settings.
Match the installed assembly
For a replacement PSE4-SL-01, 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 PSE4-SL-01; 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.
Prove the function
At commissioning, Test the complete safety function under the site-approved procedure. Test PSE4-SL-01 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 PSE4-SL-01 has the correct settings, connected accessory or alarm action. Keep the measured values and any deviations in the maintenance record.
Send a complete enquiry
An RFQ for PSE4-SL-01 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 PSE4-SL-01 variant where verified. Each other complete code needs its own specification review.
Related-looking model strings
These designations visually resemble PSE4-SL-01; they can still have different functions, ratings, interfaces and approvals. Verify each complete code independently before ordering or substitution.
No additional same-pattern code is grouped with PSE4-SL-01 here; any alternative requires its own review.
Close-out
After the handover of PSE4-SL-01, 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 PSE4-SL-01. Do not treat the product montage or the related-code index as a wiring diagram or a declaration of interchangeability.
