In industrial production, especially electronic and electrical products that can be used outdoors, there will be different levels of dustproof and waterproof requirements for equipment. The enclosure protection level (IP code / dustproof and waterproof) of automation instrumentation equipment is an important indicator to ensure the normal operation of the equipment and the protection of product safety and reliability. Then, when choosing and using instrument products, we must pay special attention to the protection level of instruments and meters, which is of great significance for correct product selection, product installation and use.
The EN60529 standard is widely used internationally to define the sealing performance of electrical equipment such as inkjet printers. The different categories of protection levels that this standard will quantify mainly include protection against solid foreign objects entering the enclosure (including tools, fingers or dust, etc.) and protection against water (water entering the enclosure by condensation, flushing, immersion, etc.) influences).
