Telemecanique XU5-N18NP340D Photoelectric Sensor

The Telemecanique XU5-N18NP340D is a cylindrical M18 threaded photoelectric sensor designed for diffuse photoelectric sensing and non-contact detection of presence and position of parts in industrial automation. It is commonly used in packaging machines, conveyor lines, sorting systems, and automated handling processes to monitor products and workpieces along a production line. This 12–24 V DC sensor uses an infrared LED light source and a 3-wire NPN output with a maximum current of 100 mA, delivered via a cable connection. The housing is nickel-plated brass and the lens is PMMA, with IP67 protection for challenging environments. Sensing distance is 100 mm, and the unit offers a 1 ms response time with a switching frequency up to 500 Hz, supporting fast line cycles and accurate detection. The XU5 family is favored by maintenance teams, OEMs, and system integrators for repair, retrofit, or new equipment integration, and it mounts via a cylindrical threaded mount. Certifications include CE. Common replacements include XU5-N18PP340, XU5P18PD9AB, and XU1-P18PP340 for related configurations.
