What IP Rating do i need for my Industrial Plugs and Sockets?

Choosing what IP Rating to select can be a confusing decision, we’ve broken it down into 4 easy steps for you. Lets start at the very beginning – 

1. What are IP Ratings?

An IP (Ingress Protection) number or code is used here in the UK to specify the environmental protection of enclosures around electronic equipment. An IP rating is a measure of an enclosure or cases ability to resist items entering it.

2. How the Coding Works

IP Ratings provide you with a more detailed guide than generic marketing terms often applied when talking about water resistance.

This means you can determine the exact levels of protection against moisture. Instead of an item simply being “waterproof”.

An IP rating is, in summary, a two digit code. The first digit establishes the level of protection against intrusion of solid foreign bodies. The second the resistance against moisture intrusion.

Together, this informs you of the precise the level of protection that will be offered by the specific case or enclosure.

Any product with an IP rating must withstand an assortment of tests. These tests determine the items’ efficiency in a range of circumstances.

Ultimately, an IP rating allows to you be able to make an educated choice regarding the appropriateness of the products’ suitability for your specific application.
