New sensors in a hygienic stainless-steel housing

Leuze has developed the 53C and 55C series for hygiene-sensitive production and packaging processes. The sensor series are suited to hygiene-sensitive production and packaging processes. A special design, high leak tightness, and resistance to cleaning agents characterise them.

When packaging or filling foodstuffs or pharmaceuticals, the highest prerequisites apply to hygiene and the cleaning of the system. With the series, the company has developed sensors ideal for hygiene-sensitive production and packaging processes. They are characterised by the housing constructed of high-quality, particularly smooth V4A stainless steel and the glass-free, scratch-resistant optics cover. The sensors can, therefore, withstand demanding cleaning and disinfection cycles and large temperature fluctuations.

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

With the devices, system operators get flexibly applicable sensors in the form of throughbeam photoelectric sensors, retro-reflective photoelectric sensors or diffuse sensors. Depending on the model, the solutions reliably detect glass, PET, film, or small parts. The fill level of aqueous liquids can also be readily detected. The new sensor series are dust-proof and waterproof and fulfil the protection classes IP67, IP68 and IP69K requirements.

The company has developed the 55C series in a wash-down design for wet areas. Optics and operational controls are constructed of non-diffusive and chemically-stable materials. A gap-free design contributes to maximum hygiene. The sensors of this series have a hygiene design. The housing is consistently designed to prevent bacterial contamination.

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