Telemecanique XUK1ARCNL2 retroreflective sensor, 7 m range, 3 A relay output, 20 to 240 VAC/VDC supply. Output is NO/NC configurable via the five-wire cable (2 m PVR). The 25 ms response is fine for conveyor presence and part-in-place checks; for high-speed counting look at a faster sibling. Enclosure is NEMA 4/4X/12/13 and IP65 — hose-down tolerant but not submersible. Body is PBT, which shrugs off most oils and mild chemicals.
Panel-fit notes
The 2 m PVR cable and LED indicators (yellow output, red stability) aid alignment; 20 Hz operating frequency limits high-speed counting.
