IP67 Vs IP68 | Similarities | Differences | Applications

You may have seen various IP ratings on your electronics like smartphones, smartwatches, etc., and you must be wondering about their meaning. These numbers and letters – also known as the Ingress Protection (IP) ratings – inform you about the level of protection your device offers against dust and moisture, ensuring its durability and reliability in various conditions. Although multiple IP ratings are available, two commonly encountered classifications are IP67 and IP68. So, to better understand these IP ratings and their benefits, we have compiled a detailed comparison between IP67 Vs IP68 for you. Let’s dive in!

Understanding IP Rating

IP stands for “Ingress Protection,” and IP ratings tell you about how resistant a device is against solids and water. These ratings consist of two digits following the abbreviation “IP.” Each digit represents a specific level of protection against different types of intrusions. The first digit shows protection against solid objects, while the second digit shows protection against liquids. To interpret an IP rating, simply combine the first and second digits. For example, an IP65-rated device offers complete dust protection (6X) and can withstand high-pressure water jets of 12.5mm nozzle.

Typically, the purpose of IP ratings is to offer you complete surety about the safety of your electronics. Unlike vague marketing terms such as “waterproof,” which lack clarity, IP ratings provide specific and detailed information about a product’s durability. 

They give a clear definition of where and to what extent an item can resist the ingress of moisture. In addition, this standardized system tells you that the products are adequately protected against dust, water, and other potential hazards and help you make an informed decision. Some examples of products with IP ratings are smartphones, smartwatches, laptops, etc. In IP67 Vs IP68, each letter has a different meaning. Let’s first discuss these letters and numbers to find the meanings behind them.
