Filler line sensor that shrugs off washdown
Square D Telemecanique XUB0ANSNM12 is a plastic 0.71 inch threaded barrel photoelectric sensor with NPN output, 12 to 24 Volt DC, and a 4-pin connector. IP65/IP67/IP69K enclosure and 2 millisecond response time. Four sensing modes in one body: diffuse to 0.98 ft, diffuse with background suppression to 0.39 ft (grabs the bottle while ignoring the rail), polarised reflex to 9.84 ft, and through-beam to 65.62 ft. Lens is PMMA, load max 100 mA, switching frequency 250 Hz. Comes with UL, CSA, CE and RoHS compliance – documentation for the QA file is standard.
Compared to the cable PNP variant
XUB0APSNL2 is the PNP 2-meter cable version – same sensing ranges, same 18mm plastic barrel, same IP67 rating. But the XUB0ANSNM12 uses an M12 connector (4-pin) instead of attached cable, and its NPN output sinks rather than sources. If your panel was wired around XUB0APSNL2, you'd need to swap the load wiring and possibly the connector, not a blind drop-in. For a fresh build, the connector saves on replacement costs when a cable gets chewed.
