The IP rating (International Protection Rating) is a classification that rates the degree of protection for electrical chassis and enclosures against environmental intrusion of solid objects, dust, debris, and water. Developed by the International electrotechnical commission (IEC), the IP rating helps set a standard to provide users with precise information rather than ambiguous marketing terms like “waterproof”. This ranking system is a more practical way to compare levels of ingress protection and pushes for uniformity in standardization. This is especially relevant in harsh industrial environments where exposure to dust or water ingress can disrupt day to day operations.
Therefore, it’s important to consider the application and potential environmental conditions your product may be exposed to. Knowing the right IP rating for your intended use can save you a lot of time and trouble in the long run. Too little and you risk potentially damaging your computer, but too much and you’re costing your company. So, what do the numbers in the IP rating exactly mean? When looking at the IP code of a product, you will find the letters IP followed by two digits. The first digit in the code indicates the level of protection of person against solid foreign objects while the second digit measures the degree of protection of equipment against water intrusion. These numbers provide more accurate and detailed descriptions of defense compared to non-specific labels. Below is a table showing the specific ingress protection for each immediate level.
|Ingress Protection||First Digit:
First Digit: Solid particle protection
|Level||Particulate Protection||Effective Against|
|1||>50mm||Any large surface of the body, such as back of the hand|
|2||>12.5mm||Fingers or similarly sized objects|
|3||>2.5mm||Tools, wires, etc.|
|4||>1mm||Small wires, screws, cables, etc.|
|5||Dust protected||Most incidental dust ingress, insufficient quantities to interfere with equipment operations|
|6||Dust tight||Complete protection against contact and entry of dust|
Second Digit: Liquid ingress protection
|Level||Moisture Protection||Effective Against|
|1||Dripping water||Vertical drops of water|
|2||Dripping water when tilted at 15°||Vertical drops of water when enclosure is tilted at 15°|
|3||Spraying water||Water falling as a spray at any angle up to 60°|
|4||Splashing & Spraying water||Splashing and spraying water from any direction|
|5||Low pressure water jets||Water projected by a nozzle from any direction|
|6||Powerful water jets||Water projected in powerful jets from any direction|
|7||Temporary immersion up to 1m||Ingress of water in quantities up to 1m of submersion|
|8||Continuous immersion beyond 1m||Continuous submersion in water, even exceeding 1m|
For industrial applications and deployments, rugged systems are standard fare for integrating electrical systems that includes computers, controllers, monitors and other devices. However, systems integrators and engineers must ensure that their equipment is also properly IP rated for specific situations that require a certain degree of ingress protection. Dusty and wet conditions are high-risk for sensitive electronic components and without the correct protection, businesses can face significant downtime and costly repairs.
Highly rated IP systems are required for proper operation in industries such as manufacturing, healthcare, water treatment and more.
Premio IP65/67 Rugged Industrial PCs
Premio offers IP certified WCO series Edge Computers that are designed and manufactured for harsh environments where protection against external elements is necessary for proper operation. They feature an extruded aluminum chassis with an airtight rugged enclosure that is rust and corrosion resistant. In addition, our cable-less and fan-less design allows for greater industrial reliability. The IP65/IP67 ratings make the WCO an ideal solution for industries including agriculture, food processing, water treatment, mining, healthcare and more.
The WCO series Edge Computers can withstand water projected by a nozzle with a pressure of up to 30kpa from any direction without any harmful effects. In food processing, this is particularly relevant as they often spray clean production lines to avoid contamination. For hospital usage, Premio’s touchscreen panel PCs are IP rated on the front bezel and resistant enough to be quickly cleaned with standard hospital disinfectants to ensure proper clean rooms.
Premio embedded computers are carefully designed to handle the threats of ever-changing outdoor conditions. Radiant heat from the sun can generate extreme temperatures that damage and overheat electronics but our rugged industrial computers can withstand wide temperatures up to 70°C. And in cases of natural disasters like flooding is where an IP67 rating becomes significant. The IP67 WCO computers expand on the IP65 capabilities with full immersion in water depth of 1 meter for up to 30 minutes. This allows it to circumvent certain flooding conditions and provides full protection to all electrical components housed within the unit.
Any type of embedded computer faces the real risk of breakdown due to harsh usage environments without proper rugged validation and certifications. The introduction of the IP rating system by the IEC sets a standard that benefits the customer with detailed information about a device.
