Leuze LS55CI.H2O/77-200-M12 (Order Code: 50148183)

Product Overview: The Leuze LS55CI.H2O/77-200-M12 throughbeam photoelectric sensor transmitter is a premium high-tier optical diagnostics instrument belonging to the world-renowned Series 55C portfolio, engineered and manufactured by Leuze in Germany. Within advanced mechanical infrastructures, high-velocity sorting lines of automated logistics distribution networks, fast continuous packaging grids, seafood processing blocks, automated dairy lines, and processing utilities experiencing continuous high-pressure hot water sanitization loops (such as automated CIP and SIP cycles), executing long-range barrier telemetry with absolute signal stability requires field components that exhibit supreme environmental ingress resistance and zero corrosion profiles.

The LS55CI.H2O/77-200-M12 configuration targets this requirement specifically, operating exclusively as the high-fidelity Transmitter module which projects a continuous infrared beam path across factory spaces. To build a functional automation loop, it must be paired and aligned directly opposite a compatible Series 55C Leuze receiver, yielding the highest tracking reliability independent of target object color, gloss finish, or surface distortion.

Product Nomenclature Breakdown: According to Leuze's official ordering criteria, the comprehensive model string LS55CI.H2O/77-200-M12 decodes into the following technical configuration block:

• LS: Identifies the hardware module functioning as the system Light Sender (Transmitter block).

• 55C: Belongs to the heavy-duty high-reliability industrial Series 55C hardware family.

• I: Configures the hardware with a pulsed Infrared light emitting engine.

• H2O: Specifies specialized environmental waterproofing matching a smooth, bacteria-repelling Wash-down Design.

• 77: Represents Leuze's internal electronic circuit and signaling logic iteration code.

• 200: Includes a pre-wired high-flex pigtail extension cable with a length of exactly 200 mm.

• M12: Terminated with a standardized quick-disconnect M12 male connector head.

Throughbeam Principle & Infrared 1450 nm Physics: The underlying technological paradigm driving the LS55CI.H2O/77-200-M12 variant leverages sophisticated Throughbeam physics based on a dedicated, continuous light obstruction path. The transmitter embeds a powerful emitting diode that projects an alternating optical wave vector using a specialized Infrared LED light source with an extended 1450 nm wavelength straight toward the opposing receiver unit. In the standard unobstructed baseline state, the receiving thấu kính array captures this invisible soundwave light input, keeping internal data loops secure. The moment an oncoming medium (such as a structural glass bottle, plastic milk container, parcel box, or heavy wooden pallet) steps into the spatial cross-section, the light energy path is broken, routing an instantaneous discrete signal straight to a central PLC node.

Because the emitting and receiving hardware are housed inside separate isolated frameworks, the system achieves a spectacular guaranteed operating range spanning from 0 to 64 meters. The typical absolute maximum tracking boundary reaches smoothly from 0 to a massive 80 meters, completely outperforming standard diffuse or retro-reflective optical devices and offering ideal deployment for extended factory conveyor tracks or wide perimeter automated safety gates.

🛠️ 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 reinforced with Molypden. This structural metallurgy delivers exceptional resistance to aggressive chemical breakdown, pitting, and oxidation from exposure to marine salt grids, acidic sanitizing washes, or caustic alkaline compounds, guaranteeing decades of continuous runtime without mechanical decay.

• 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 IP69K standard verifies that internal calculation circuits remain entirely unaffected by severe continuous washdowns using high-pressure steam cleaning jets and high-temperature water streams, making it a perfect part choice for hygienic food processing lines and pharmaceutical cleanrooms.

Electrical Specifications & Pigtail Interface Layout: The LS55CI.H2O/77-200-M12 transmitter runs smoothly on a flexible industrial utility range of 10 to 30 VDC, consuming an exceptionally efficient no-load current of less than or equal to 15 mA. The internal solid-state circuitry handles demanding thermal environments spanning from minus 40 up to plus 60 degrees Celsius, allowing deployment in sub-zero food flash-freezing grids.

Electrical interface routing is managed via a pre-wired, high-flex 200 mm pigtail cable terminated with an A-coded, M12, 4-pin male socket link. This pigtail layout minimizes mechanical bending stresses on the main housing joint when deployed inside cramped machine bays, maximizing structural cable lifespan. The standard pinout map allocates Pin 1 to positive 24VDC utility supply and Pin 3 to negative common, while Pin 2 and Pin 4 function as diagnostic input channels designed for remote sensitivity calibration loops. 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.
