The food and beverage industry is heavily regulated in terms of health and hygiene compliance. Human Machine Interfaces (HMIs) allow direct data flow collection and communication between machines and facilities, as well as real-time monitoring and control of operational processes, to create fast and collaborative manufacturing processes. While maintaining contact with chlorides and corrosive substances, hardware design must consider whether it can withstand intensive spraying and repeated high pressure cleaning. InnoAioT stainless steel fanless panel PCs are specially developed to meet the design requirements of the food industry. Using SUS304/AISI316 stainless steel material and M12 type connectors to achieve IP69K protection, it can be easily integrated into extremely hygienic environments.
