What Exactly Is the Difference Between IP66 and IP67?

What is IP67 and what is the difference between it and IP66? This is probably the question that JRPanel engineers have been asked most often recently.

On the online pricing page of JRPanel's website, a new option appears in the Rear Adhesive section: 3M300LSE & Waterproof ( IP67 ).

In fact, this is a waterproof process recently upgraded by the JRPanel factory. This process can bring more possibilities to your products, and it also marks that JRPanel's products have reached a new level.

So what is the difference between IP67 and the previous IP66 process? In this article, we will explain in detail.

In the previous article Criteria for the Classification Ratings of Ingress Protection, we introduced that the ingress protection rating is composed of two digits. The first digit represents the level of the electrical appliance's ability to prevent intrusion of foreign objects, and the second digit represents the degree of airtightness of the electrical appliance against moisture and water intrusion.

As can be seen from the figure below, for the first digit, the larger the number, the stronger the protection ability. But for the second digit, especially the difference between IP66 and IP67, it is often misunderstood that IP67 is more waterproof than IP66.

From the figure above, we can see that the "Protected Against" and "Effective Against" of IPX6 and IPX7 are not the same. IPX6 is "Powerful Water Jets", while IPX7 is "Immersion up to 1 meter". Since the protection purpose and protection conditions of the two are inconsistent, we cannot simply assume that the protection level of IP67 is higher than that of IP66.

It can be seen that IPX7 and IPX6 represent the protection level under two different conditions. We can understand it this way: products with a protection level of 7 or 8 in the second digit only have a protective effect against short-term immersion or continuous immersion, and do not have a protective effect against water jets (the second digit is marked with 5 or 6).

If a product is marked with IP66 and IP67 at the same time, it means that this product meets the protection requirements for water jets or short-term and continuous immersion.

Now I believe you already have a deep understanding of the difference between IP66 and IP67. Then how does JRPanel apply the IP67 process to Membrane Switch & Panel? Stay tuned to our Blog and we'll bring it to you in the future!

Brief Introduction to Flat Spiral Coil Inductors

Hi guys! Today JRPanel would like to share a few points about Flat Spiral Coil Inductors with you. Basically, a flat coil inductor is an inductor wound with flat copper wire. The picture below is the side view, we can see that each circle of copper wire is arranged very compact. Here are some of the application characteristics of flat coils : 1. High current inductance 2. Lowest DC resistance 3. Can ensure smooth drop of current-resistant inductance 4. Suitable for reflow SMT process 5. Lead-free, RoHS compliant This pciture shows a flat coil product. It is generally used in power supplies, personal computers and other handheld electronic devices . Advantages of F lat C oil I nductors are : 1. Scientific and reasonable space design. 2. Tight and flat between turns ensures the effective cross-sectional area of the wire, which greatly reduces the copper loss ...

Identify Different Types of Transformer Cores, Based on Materials

Hi guys, this is JRPanel ! In previous blog s, we have introduced several points about High Frequency Transformer, like bobbins and Flat Spiral Coil . In this blog, JRPanel would like to introduce the commonly used magnetic cores in transformers , based on materials. Generally speaking, the material of the core determines the environment in which the transformer is used. A transformer that uses a core of a different material will have its performance affected, may even be non-functional. By material, magnetic cores are generally divided into the several categories . JRPanel will introduce them one by one to help you understand more fully. 1. Manganese Zinc Ferrite Core Mn-Zn core is a soft magnetic core with high initial permeability (2000~15000). The higher the initial permeability, the lower the surface resistance, so it is generally used in circuits below 1 MHz. Mn-Zn core has a high saturation ...

The Real Voice of JRPanel Users From All Over the World

Since the birth of the brand, JRPanel has been upholding the goal of becoming a "one-stop professional intelligent manufacturer" , having witnessed the successful output of hundreds of customized products for enterprises. B ecause of this long-term goal that JRPanel has grown and become famous in the overseas manufacturing market for its "High Q uality", " F ast D elivery", and " Excellent S ervice" . As of May 2022, JRPanel's products have been exported to 40 countries and regions. However, no matter how a company promotes its brand, it is not as real as a few simple comments from customers. So what do JRPanel's partners say about JRPanel? In this blog, we will select some representative comments and show them based on four aspects: high product quality, excellent service, intelligent platform and rapid delivery. This will help you understand the true image of JRPanel in the minds of our partners around the world. (The follo...
