Absolute hygiene in stainless steel


Two new sensor series in miniature stainless steel housing: Leuze has developed the 53C and 55C series especially for hygiene-sensitive production and packaging processes.


Owen, May 12, 2023 – Whether cheese, drinking water or vaccines: When packaging or filling foodstuffs or pharmaceuticals, the highest requirements apply to hygiene and the cleaning of the system. With the 53C and 55C series, Leuze has developed sensors that are ideally suited for hygiene-sensitive production and packaging processes. They are characterized by the housing made of high-quality, particularly smooth V4A stainless steel and the glass-free, scratch-resistant optics cover. The sensors can thus withstand demanding cleaning and disinfection cycles as well as large temperature fluctuations.


Precise at all times

With the 53C and 55C series, system operators get flexibly applicable sensors in the form of throughbeam photoelectric sensors, retro-reflective photoelectric sensors or diffuse sensors. Depending on the model, Leuze solutions reliably detect glass, PET, film or small parts. The fill level of aqueous liquids can also be easily detected. The new 53C and 55C sensor series are dust-proof and waterproof and meet the requirements of protection classes IP67, IP68 and IP69K. Useful: The sensors can be configured, operated and maintained via IO-Link.


No chance for bacteria

For wet areas, Leuze has developed the 55C series in a Wash-Down design. Optics and operational controls are made of non-diffusive and chemically-stable materials. A gap-free design contributes to maximum hygiene.

The sensors of the 53C series have a HYGIENE design: The housing is consistently designed to prevent bacterial contamination. Smooth contours without fastening holes prevent deposits. A special fastening concept also contributes to this: The sensor and the machine have a gas-tight connection via the mounting trunnion. The 53C series is suitable for particularly hygiene-sensitive areas with direct contact with food or for installation above unpackaged products.
