The Square D / Telemecanique XUYFALNEP100080 is a photoelectric fork sensor from the XUY-series line, catalogued under the Photoelectric Sensors family. It carries UPC 389119006807 for PO-line and receipt cross-checking, and sits in the current production stage on the manufacturer's line card.
Where the fork sensor class fits in a panel
Fork-style photoelectric sensors are used where a label edge, thread, tab or small part has to be detected as it passes through a fixed slot — typically on conveyors, labelling heads, packaging machines and printing lines, where the emitter and receiver are pre-aligned in one body so the installer does not have to sight two separate heads. The XUYFALNEP100080 drops into that slot as a self-contained detection block, wiring straight to a discrete input on the machine PLC without the optics alignment a through-beam pair demands.
