Understanding IP Ratings: What They Mean and Why They Matter
When buying electronics or outdoor equipment, you might have noticed a code like IP65 or IP68 printed on the packaging. These are called IP Ratings — short for Ingress Protection Ratings — and they tell you how well a device is protected against dust and water.
In this post, we’ll break down what IP ratings mean, how they’re structured, and what the most common ratings represent.
What Is an IP Rating?
The IP rating, established by the IEC 60529 standard, measures how effectively a device’s enclosure prevents dust and water from entering.
Each IP code includes two digits:
The first digit specifies the level of protection against solids and dust. The second digit shows protection against water or moisture.
For example, in IP67:
The “6” means the device is completely dust-tight.
The “7” means it can withstand temporary immersion in water up to 1 meter deep.
Why IP Ratings Matter?
A clear understanding of IP ratings ensures you choose equipment that meets the environmental protection requirements of your application.
Outdoor devices (like CCTV cameras or lights) need at least IP65 or higher. Mobile devices benefit from IP67 or IP68 for water and dust resistance. Industrial settings often require IP69K for protection during high-pressure cleaning.
Choosing the correct IP rating ensures your device performs reliably and lasts longer — even under harsh conditions.
