The Telemecanique XUY1119 is a reflector for photoelectric sensors, listed under the Sensor Cables category. It's a passive component — no electronics, no wiring — just the reflective surface that bounces the beam back to the sensor head.
This reflector is a Square D / Telemecanique branded part (UPC 389119009600). It's a standard catalog item — not a special order. The XUY1119 is a reflector only, not a sensor head or cable assembly. If you're replacing a complete photoelectric sensor setup, verify the sensor head model separately — this part is just the target reflector.
