The Telemecanique XUB0APSNM12 is an 18mm tubular photoelectric sensor with a PNP output, rated for 12 to 24 VDC. It covers multiple sensing modes: diffuse to 30 cm, background suppression to 12 cm, polarized retroreflective to 2 m, and through-beam to 15 m. The 2 ms on/off response and 250 Hz switching frequency keep up with high-speed pass-by detection on packaging lines. Supply is current-active, so no last-time-buy crunch to worry about.
The IP67 and NEMA 4X/12 enclosure means it holds up in washdown areas. Background suppression mode lets it ignore shiny background surfaces. The M12 4-pin male connector with 3 wires is a standard breakout; any M12 pre-wired cable works. UL, CSA, CE approvals cover most panel specs. The 100 mA maximum load current and PNP output are within the typical PLC input range.
