In this article, we will explore IP rating, their significance, the codes used to classify them, their applications, and other essential aspects to help you make informed decisions when choosing devices with appropriate IP ratings.

What is an IP Rating?

An IP rating, also known as an Ingress Protection rating, is a standard measure used to indicate the degree of protection provided by an enclosure or device against the ingress of solid objects and liquids. It helps consumers understand the level of protection an electronic device offers in different environmental conditions.

Understanding IP Rating Codes

IP rating codes consist of two digits. The first digit represents the level of protection against solid objects, while the second digit represents the level of protection against liquids. The higher the digits, the greater the protection.

The First Digit: Protection against Solid Objects

The first digit in the IP rating code signifies the device's protection against solid objects such as dust, debris, or human contact. It ranges from 0 to 6, with higher numbers indicating higher levels of protection. For example, an IP rating of 0 means no protection against solid objects, while an IP rating of 6 signifies complete protection against dust.

The Second Digit: Protection against Liquids

The second digit in the IP rating code indicates the device's protection against liquids, including water. It ranges from 0 to 9, with higher numbers representing higher levels of protection. For instance, an IP rating of 0 means no protection against liquids, while an IP rating of 9 signifies protection against high-pressure and high-temperature water jets.

	Ingress of solid objects	Ingress of liquids
0	No protection	No protection
1	Protected against solid objects over 50mm e.g. hands, large tools.	Protected against vertically falling drops of water or condensation.
2	Protected against solid objects over 12.5mm e.g. hands, large tools.	Protected against falling drops of water, if the case is disposed up to 15 from vertical.
3	Protected against solid objects over 2.5mm e.g. wire, small tools.	Protected against sprays of water from any direction, even if the case is disposed up to 60from vertical.
4	Protected against solid objects over 1.0mm e.g. wires.	Protected against splash water from any direction.
5	Limited protection against dust ingress.	Protected against low pressure water jets from any direction. Limited ingress permitted.
	(no harmful deposit)
6	Totally protected against dust ingress.	Protected against high pressure water jets from any direction. Limited ingress permitted.
7	N/A	Protected against short periods of immersion in water.
8	N/A	Protected against long, durable periods of immersion in water.
9	N/A	Protected against close-range high pressure, high temperature spray downs.

Interpreting IP Rating Examples

To illustrate the interpretation of IP ratings, consider the example of a device with an IP rating of IP67. The first digit, 6, indicates that it is dust-tight, offering complete protection against solid objects. The second digit, 7, suggests that it is protected against the effects of temporary immersion in water up to a certain depth and duration.
