What it is, in plain terms
The Telemecanique Sensors XUY41013 is a block/rectangular background-rejection photoelectric sensor from the XUY series — the diffuse-reflective head that ignores a target's colour or reflectivity and reads only the geometry, so a dark carton on a dark belt still produces a clean switching point where ordinary photoelectric eyes would miss or false-trigger. Background-suppression units in this body style typically anchor conveyor-side part detection, tray-present checks, and small-part registration on packaging and assembly lines — anywhere the light/ dark or colour of the target cannot be controlled and the only usable cue is where the target physically sits. Carry the commerce identifier 389119019913 when matching existing BOMs and tear-down spares lists; if the existing line on a quote sheet reads Telemecanique XUY41013, this is the part it points at.
Lifecycle posture for the cabinet
Lifecycle stage reads current, so the spares drawer stays straightforward — hold one in the cabinet against the next background-rejection failure on a line that already runs XUY-series heads rather than scrambling after a breakdown.
Sourcing posture
Quote it to order against an RFQ against the exact code XUY41013 and the UPC 389119019913; we work the spec line into the BOM as written rather than substituting off a parametric guess.
