reason, smooth surfaces without gaps and cavities are required. Leuze meets these requirements by implementing a hygienic product design and using selected FDA-compliant materials. This means that Leuze sensors for the food industry have a stainless steel housing as well as glass- free and scratch-resistant optics covers.
PRECISE AND ROBUST AT THE SAME TIME
The requirements make it clear that suitable sensor systems are needed for hygiene- sensitive production and packaging processes. Leuze has specially developed the 53C and 55C sensor series for this purpose. 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.
SENSOR SYSTEMS FROM THE EXPERT Anyone wanting to be on the safe side when it comes to sensor systems used in the food industry should opt for a sensor manufacturer with extensive expertise in this area. Hundt explains: “Leuze not only understands the challenges in hygiene-sensitive
environments, but has for decades worked closely with its customers from the food industry. We implement the Sensor People’s
comprehensive application knowledge in optimum sensor solutions for every requirement.” The high- tech product range includes a number of different sensors for the field of automation technology. For example, switching and measuring
sensors, identification systems, data transmission and image processing solutions as well as safety components, services and holistic solutions. Another advantage: Leuze covers not only a sub-process, but provides its customers from the food industry with assistance from the first to the last step in the packaging process completely and at all times.
FOOD-SAFE IN STAINLESS STEEL Leuze has developed the sensors of the 53C and 55C series especially for hygiene-sensitive production and packaging processes. They can be used very flexibly as through beam 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 53C and 55C sensor series are dustproof and waterproof and meet the requirements of protection classes IP67, IP68 and IP69K. The housing is consistently
designed to prevent bacterial carry-overs and contamination. Smooth contours without fastening holes prevent deposits. A special fastening concept of the 53C series in hygienic design also contributes to this: The sensor and the machine have a gastight connection via the mounting trunnion. Additionally, the sensors can be configured, operated and maintained via IO-Link.
