What is an IP Rating?
An IP (Ingress Protection) rating is a unit used to define the levels of protection an electrical enclosure offers to any contents and assemblies housed inside. This is calculated by measuring the enclosure's sealing effectiveness from any moisture or foreign bodies (tools, dust, dirt etc).
To ensure your components are sufficiently protected, it’s important to understand what each digit relates to and what IP rating you require from an enclosure. Using IP65 as an example, the first digit ‘6’ is used to define the level of protection offered from solid objects & foreign bodies, whilst the second digit ‘5’ is used to measure the level of protection offered from liquid objects & moisture.

IP ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:19889).
