This Telemecanique XU9M18MA230K is a current-production polarized retroreflective photoelectric sensor in an 18 mm nickel-plated brass barrel. It throws a 3 m sensing beam and runs on anything from 24 to 240 VAC or VDC, so you don't need separate supply rails for AC and DC panels. Output is a solid-state transistor switching 10–200 mA, with a 20 ms response. The IP67 enclosure means it survives washdown and dust. Approvals: UL, CSA, CE — covers most North American and European installs. RoHS compliant; no extra compliance legwork.
UPC 78590130126 ties to this exact variant. If you're sorting a liquidation pallet, that's the number to cross against manifests or old MRO bins.
