Identifying OBT20-R102-2P1-IO-V31 in the field and confirming its signal path
Pepperl+Fuchs OBT20-R102-2P1-IO-V31 is a triangulation photoelectric sensor for detecting a close target with background suppression. The shared product montage is a category reference image rather than a photo of this exact OBT20-R102-2P1-IO-V31 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.

On-site proof
After OBT20-R102-2P1-IO-V31 is connected, Run both dark and reflective samples and inspect output states at the intended distance. 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 OBT20-R102-2P1-IO-V31 has the correct configuration.
Application path
In this installation, OBT20-R102-2P1-IO-V31 supports detecting a close target with background suppression. 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 OBT20-R102-2P1-IO-V31 code is the procurement reference, while the as-installed drawing is the acceptance reference.
Installation interface
Before fitting OBT20-R102-2P1-IO-V31, Verify the actual sensing gap, background surface, M8 pinout and IO-Link parameter set. 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 OBT20-R102-2P1-IO-V31 variants can share an enclosure while differing in function.
Replacement decision
When purchasing OBT20-R102-2P1-IO-V31, Other OB-looking codes listed below can be different optical functions; compare complete suffixes. 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 OBT20-R102-2P1-IO-V31; a similar-looking code is a search reference, not a declared equivalent.

Handover note
Keep the drawing, configured settings, inspection result and purchasing record with OBT20-R102-2P1-IO-V31. Recheck the current manufacturer datasheet if the duty, mounting, network or approval changes. This closes the OBT20-R102-2P1-IO-V31 selection and commissioning review without treating related codes as interchangeable.
