XU5N18PP341 Photoelectric Sensor, Diffuse Infrared, PNP, IP6

The XU5N18PP341 is a Series XU diffuse photoelectric sensor with an infrared light source. Sensing distance is 100 mm on a standard reflective target — enough for detection on conveyor belts, packaging lines, or part-present gating. It runs on 12–24 VDC and outputs a PNP signal with selectable NC or NO logic. That selection is done at the connection — no DIP switch inside, so it's a wire-configurable choice between a dark-on or light-on circuit. The housing is IP67 rated with a 2-meter PVC cable pre-attached. Temperature span is -25 to 55 °C, which covers most indoor environments. The diffuse method means no separate reflector — the target itself returns the beam back. Keep the optical window clean; any buildup degrades range.
