IP65:
Protected against low-pressure jets of water from all directions.
IP66:
Protected against strong jets of water.
IP67:
Protected against the effects of immersion in water at a depth of 1 m.
IP68:
Protected against the effects of continuous immersion in water at a depth exceeding 1 m.
IP69K:
Protected against high-pressure water and steam jet cleaning
The demands placed on electric and electronic devices can be extreme. Often, they must function safely and reliably over many years in the most difficult environmental conditions to protect their users. In addition to preventing water penetration, devices must also offer protection against external influences and conditions, such as mechanical impacts, moisture, corrosion, etc. Next to the temperature in the area of application, resistance against corrosion is a crucial factor. It indicates how durable the devices are when faced with aggressive substances such as moisture, water, vapors, acids, alkalines, oil, or fuels. In addition, it also indicates the devices' degree of protection against penetration by foreign solids such as dust, bacteria, or viruses. The IP codes stand for different protection classes and provide information about how well the respective system is protected from the environmental influences that it operates in. Coding complies with standards DIN 40050 and IEC 60629.
IP codes – composition and practice
IP codes are composed of two digits. These indicate different protection aspects of the marked system. IP6X refers to an enclosure that is dust-tight, whereas IPX9K refers to the ability to keep out water from high pressure/steam cleaning. One feature of note: For devices with a code above IP66, the other, lower protection classes valid for the device must additionally be indicated.
Protection class for dust-tight systems that are protected against water jets from different angles.n
Protection class for dust-tight systems that are protected against strong water jets.n
Protection class for dust-tight systems that are protected against temporary immersion.n
Protection class for dust-tight systems that can be used underwater permanently.n
Before an electrical system is awarded the protection class IP69K, it must be tested in the harshest conditions. With water pressure of 80 to 100 bar, in phases of 14 to 16 l/min, and temperatures up to 80° Celsius. With its extreme resistance and safety during exposure to high pressure and steam, this protection class was originally developed for the automotive industry. It has since also become the standard for the food and beverage industries.
Packaging liquid products places maximum demands on cleanliness. For one of our customers, we worked in collaboration to develop an application-specific packaging system that uses environmentally friendly packaging material and includes an automatic filling station: It's easy to set up, requires little maintenance, and can be operated by only one employee.
