Absolute hygiene in stainless steel

June 16, 2023 Industrial News

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

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 characterised 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.

Leuze 53C series diffuse sensors have a HYGIENE design without drilled holes and are suitable for areas of application with direct contact with food. They also reliably detect the leading edges of cut-good products

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.

Reliably detecting the fill level of aqueous liquids in containers is one of the most demanding detection tasks. This requires particularly powerful sensor solutions such as the throughbeam photoelectric sensors of the 55C series from Leuze, which have been specially optimised for this application

No chance for bacteria

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

The housing is consistently designed to prevent bacterial contamination. Smooth contours without fastening holes prevent deposits.

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.
