Leuze LE55CI.H2O/4P-200-M12 (Order Code: 50148184)

Product Overview: The Leuze LE55CI.H2O/4P-200-M12 throughbeam photoelectric sensor receiver is a specialized process-grade liquid diagnostics instrument belonging to the world-renowned heavy-duty metal Series 55C portfolio, engineered and manufactured by Leuze in Germany. Within advanced mechanized infrastructures, high-velocity sorting lines of automated beverage bottling networks, continuous dairy packaging cells, processing vats, and automated chemical lines, executing flawless fluid fill-level telemetry across transparent or tinted container walls without experiencing interference from container material density is a substantial technical demand.

The LE55CI.H2O/4P-200-M12 configuration targets this requirement specifically, operating exclusively as the high-fidelity Receiver module which tracks direct infrared beam transmission. To build a functional automation loop, it must be paired and aligned directly opposite a compatible Series LS55C Leuze transmitter, yielding a rugged, independent water sensing barrier loop that remains uncompromised by package transparency, color variance, or changing exterior labels.

Nomenclature Product Code Breakdown: According to Leuze's official ordering criteria, the comprehensive model string LE55CI.H2O/4P-200-M12 decodes into the following technical configuration block:

Water Sensing Telemetry and Infrared 1450 nm Spectroscopy Physics: The underlying technological paradigm driving the LE55CI.H2O/4P-200-M12 variant leverages sophisticated optical chemistry principles based on the molecular properties of water. Water molecules exhibit a high absorption peak when exposed to infrared light waves near the 1450 nm spectrum. Utilizing this physical property, the system transmitter projects a continuous pulsed infrared wave vector centered at the 1450 nm wavelength straight toward the opposing receiver thấu kính array.

In the standard unobstructed baseline state (such as an empty bottle run or an empty pipeline section), the infrared beam passes smoothly across the open gap, delivering full energy to the receiver core. The moment an oncoming medium containing water content (such as filled beverage bottles, liquid dairy products, or passing pipeline fluid flows) steps into the spatial cross-section between the two units, the water volume absorbs the 1450 nm light energy wave, causing a severe, immediate attenuation of the light path.

The internal digital processor analyzes this microscopic light intensity sụt giảm loop with high resolution, instantly switching the logic state of the solid-state transistor outputs to pass automated control discrete data over cable lines. Because this mechanism tracks molecular light absorption physics rather than pure shadow blocking, it eliminates tracking errors caused by transparent container layers, clear plastic walls, or colored glass finishes. The effective application range locks smoothly between 0 and 500 mm, making it perfectly optimized for tight mechanical conveyor kẹp setups tracking bottling currents.

🛠️ CRITICAL HARDWARE ADVANTAGE & WASH-DOWN INGRESS TOUGHNESS:

• Austenitic AISI 316L Stainless Steel Housing Hardening: The structural casing of the sensor is machined entirely from premium grade AISI 316L stainless steel alloy. This structural metallurgy provides an ultra-smooth finish exhibiting a surface roughness metric of Ra less than or equal to 0.8 micrometer, entirely repelling bacterial colony growth and biofilm adhesion. It delivers exceptional resistance to aggressive chemical breakdown, pitting, and oxidation from exposure to marine salt grids, acidic descalers, or caustic alkaline compounds.

• Elite IP67, IP68, and IP69K Protection Standards: Paired with its smooth, cavity-free metal shape designed to prevent bacterial colonies, the transmitter achieves elite international environmental protection ratings including IP67, IP68 (continuous immersion handling), and IP69K. The housing passes global CleanProof+, ECOLAB, and Johnson Diversey material safety compliance certificates. This ensures the internal circuits remain entirely unaffected by severe continuous washdowns using high-pressure steam cleaning jets and high-temperature water streams (handling thermal shocks up to plus 70 degrees Celsius over short intervals, outside its wide standard operational window of minus 40 to plus 60 degrees Celsius), making it a perfect part choice for automated CIP/SIP sanitation networks.

High-Frequency Signal Output Architecture and Electrical Specs: The receiver provides concurrent real-time data loops via two independent solid-state channels: Output 1 (PNP - Light Switching / Light ON / Active on clean transmitter beam loop) and Output 2 (PNP - Dark Switching / Dark ON / Active on beam break caused by water absorption). This dual architecture passes high-fidelity discrete telemetry straight to remote central PLC nodes or automated SCADA platforms without requiring secondary panel inversion relays, maximizing mechatronic looping speeds.

The internal electronics resolve process velocity changes with an ultra-fast response speed of precisely 1.43 ms (matching a high-frequency electronic switching pulse rate of 350 Hz), tracking high-density product currents without totalization errors or item dropouts on high-speed transport lines.

Electrical interface routing is managed via a pre-wired, high-flex 200 mm pigtail cable terminated with an A-coded, M12, 4-pin stainless steel male connector head. This pigtail layout minimizes mechanical bending stresses on the main housing joint when deployed inside cramped machine bays, maximizing structural cable lifespan. The physical block dimensions are exceptionally compact, showing a width of 14 mm, a height of 35.4 mm, and a length of 25 mm with a net mass of 59 grams, flanked by integrated high-visibility LED status blocks providing clear real-time diagnostics for input power validation and output state verification.
