The Leuze LSS 55.H2O,200-S12 is a high-precision optical transmitter from the established Series 55 portfolio engineered by Leuze electronic (Germany). Acting as the optical emitting powerhouse designed to pair seamlessly with the LSE 55/441.H2O,200-S12 receiver, this device establishes a dedicated throughbeam sensing barrier specifically calibrated for water-based liquid detection applications.

Utilizing optimized pulsed infrared LED emission, the transmitter delivers an optical beam specifically configured to penetrate transparent and translucent packaging materials—such as clear glass vials, PET containers, and PE bottles—while being strongly absorbed by water molecules and aqueous solutions. This physical property generates high contrast attenuation, providing precise fill-level verification, air-gap detection, and surface moisture presence monitoring without direct product contact.

Built for dependable industrial operation, the Leuze LSS 55.H2O,200-S12 features a reinforced engineering plastic housing offering superior mechanical resistance and IP67 ingress protection against dust and water penetration. Its compact physical footprint allows straightforward mounting in constrained machine structures. Equipped with an integrated 200 mm tail cable and a standardized 4-pin M12 connector (S12), it guarantees vibration-proof electrical connection and rapid field maintenance across high-speed packaging, beverage bottling, pharmaceutical filling, and cosmetic automation lines.
