The Leuze LSE 55/441.H2O,200-S12 is a specialized optical receiver belonging to the high-performance Series 55 engineered by Leuze electronic (Germany). Designed to pair seamlessly with its corresponding optical transmitter, this device forms an independent throughbeam sensing barrier specifically calibrated for water-based liquid detection applications. Utilizing advanced optical receiving sensitivity tailored to the attenuation characteristics of infrared light in water molecules, the receiver provides immediate and dependable detection whenever liquid presence interferes with the optical path.

This sensor delivers an effective solution for challenging inspection tasks in automated packaging and bottling processes: non-contact fill-level verification inside transparent or translucent containers (such as clear glass vials, PET, and PE bottles). Even in the presence of minor liquid splashing on container walls or complex optical refraction caused by curved surfaces, the Leuze LSE 55/441.H2O,200-S12 ensures superior signal integrity, eliminating false switching and boosting line yield.

Mechanically robust, the unit is housed in high-grade industrial-strength polymer engineered to resist chemical exposure and mechanical shock, achieving an IP67 ingress protection rating against dust and liquid penetration. Its compact physical envelope combined with a 200 mm pigtail cable and standard 4-pin M12 connector allows effortless mounting in space-restricted machinery. With high-speed PNP switching outputs and a response time of just 0.5 ms, it guarantees precise, high-speed tracking for modern beverage, brewing, pharmaceutical, and chemical packaging lines.
