The Leuze LE55CI.H2O/4P-200-M12 (Part No.: 50148184) is a premium throughbeam photoelectric sensor receiver from the Series 55C Wash-Down portfolio by Leuze electronic (Germany). Acting as the precision optical receiving counterpart to the LS55CI.H2O transmitter, this device is engineered with advanced spectral filtering specifically tuned to the 1,450 nm infrared wavelength. Because water and aqueous solutions strongly absorb light at this exact wavelength, the receiver delivers exceptional contrast sensitivity to detect liquid presence and verify fill levels inside transparent packaging with unmatched reliability.

Manufactured in strict compliance with hygienic design standards, the unit features a monolithic AISI 316L stainless steel housing (DIN 1.4404) with an ultra-smooth surface finish of Ra ≤ 0.8 µm. This design eliminates dirt traps, bacterial harborage points, and contamination risks. The optical window is constructed of durable PMMA+ reinforced with a scratch-resistant Indium protective layer, offering superior endurance against aggressive washdown chemicals certified by ECOLAB and CleanProof+.

With outstanding ingress protection ratings of IP67, IP68, and IP69K, the sensor easily withstands routine high-pressure, high-temperature washdowns (CIP/SIP) up to 70 °C. The unit is equipped with two configurable PNP switching outputs (light/dark switching) boasting a high switching frequency of 1,000 Hz and a fast 0.5 ms response time for flawless tracking on high-speed production lines. Terminated with a 200 mm cable and an industry-standard 4-pin M12 connector (A-coded), it ensures quick, durable, and error-free installation across Food & Beverage, Pharmaceutical, and Cosmetic automation processes.
