Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The PR-MB15P3 is the device-level element in a Keyence photoelectric sensor installation. It receives the field signals and control supply listed above — 10...30 V DC (IEC 60947-5-2) — and switches or conditions the load within the the rated ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in conveyor object detection, machine guarding, position feedback, where the unit is matched to the original catalog number and the enclosure provides standard panel or DIN-rail support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Keyence PR-MB15P3 — Sensor or detector for object detection, distance measurement and status feedback on production lines. The figures below are taken from the specification table on this page for catalog number PR-MB15P3; verify the catalog number against your bill of materials before requesting a quotation.
Cross-check the ratings above with the installed device before confirming the order.
Q.Which value is published under supply voltage for catalog number PR-MB15P3?
For PR-MB15P3, supply voltage is given as 10...30 V DC (IEC 60947-5-2). Compare it with the nameplate of the installed unit before ordering.
Q.Before ordering PR-MB15P3, which response time entry should be checked?
The response time entry quoted above is <= 1000 Hz switching frequency. Confirm this figure against the unit currently in the panel.
Q.Where can I find the output type (PNP/NPN) data for PR-MB15P3?
It is listed in the specification table for Keyence PR-MB15P3 as PNP. Use the value as the reference when sourcing a current-production equivalent.
Q.How do I confirm compatibility of PR-MB15P3 before ordering?
Match the catalog number PR-MB15P3 and the specification values listed above against the installed unit, then confirm the firmware or hardware revision where a revision-sensitive part is involved.
Q.Can the PR-MB15P3 replace the unit currently installed in my panel?
Compare catalog number PR-MB15P3 and the ratings above with the nameplate of the installed device. A current-production equivalent is selected by function and electrical rating, not by the label alone.
