What lands on the BOM line
The Telemecanique XUYFNEP40050 is a photoelectric fork sensor in the XUY series, sold under the Square D Switches & Sensors brand, used in conveyor and parts-detection applications where a fixed U-shaped optical throat replaces a separate emitter/receiver pair. It carries UPC 389119006234 and is logged as current lifecycle, so it remains specifiable into a new BOM without a last-time-buy clause.
Sourcing posture
With lifecycle logged as current, the XUYFNEP40050 is the kind of part you specify into a BOM and quote to order — no broker dependency, no PCN window to chase. If the description-row drift between XUYFNEP40050 and XUYFNEP40002 ever resolves into a real PCN, that is when you start the last-time-buy conversation; right now the part is bought forward against an RFQ the same as any active catalog line.
