The 0.3 m cable terminates in an M8 plug (3-pin rotatable thread), so it connects directly into a standard M8 sensor jack without a separate pigtail.
The sibling SIES-8M-PO-24V-K-0,3-M8D shares the same housing, cable length, and M8 connector but switches PNP normally-closed instead of normally-open. If your safety circuit or PLC input expects a closed-to-open transition on target detection, the PO variant is the one; if you need a signal that goes high when metal enters the sensing field, this PS version is the fit. No rewiring is needed to swap between them — same pinout, same mounting footprint.
