Sensors in Hygienic Design

The sensors for hygienic applications are ideal for use in the food and pharmaceutical industries. Thanks to the high-quality stainless steel 316L housing, they are robust and corrosion-resistant.
Thanks to the high IP69K protection, the sensors can be integrated into and on systems where they can withstand high-pressure cleaning at up to 100 bar and water temperatures of up to 80 °C. They are ECOLAB-certified and can withstand aggressive cleaning agents. Hygienically designed housings with no edges, crevices or angles where debris could build up make the sensors suitable for use in hygienically sensitive areas. They are also FDA compliant through the use of food-safe materials.

Photoelectronic sensors can detect or count objects contactlessly using light. The high-quality hygienic housing in stainless steel 316L (1.4404/V4A) is characterized by its special round shape without dirt edges and hermetic seal. The hygiene series is available as an energetic reflex sensor, reflex sensor with background suppression, through-beam sensor and retro-reflex sensor for transparent objects. Different types of light, such as red light, infrared light or red laser light are available depending on the intended use.

Hygienically Designed Sensors in Use – Clean Outside, Intelligent Inside

Yogurt Pot Presence Check

In the production of yogurt, it is important to ensure that there is a pot in each recess of the indexing belt before applying the lids. After each production, the indexing belts are cleaned via high-pressure jets and CIP cleaning. The FDA-compliant sensors meet these hygiene requirements – thanks to their special stainless steel 316L design, all water drops run off and the lenses do not fog up.

Food Tray Detection

When portioning meat, trays must be reliably detected on conveyors with a width of just 150 mm. The belts are cleaned at regular intervals with high-pressure jets and CIP cleaning. The FDA-compliant sensors are waterproof (IP68/IP69K) and resistant to cleaning agents, so they can withstand the high hygiene requirements.
