What does an IPX4 rating specifically protect against?

An IPX4 rating indicates that the equipment is protected against water splashes from any direction. The "IP" stands for "Ingress Protection," and it is followed by two digits that indicate the level of protection. In this case, the "X" signifies that the protection against solid particles, such as dust, is not specified, while the "4" denotes that it can withstand water splashes.

Equipment with an IPX4 rating can tolerate water splashing onto it, which is important for devices that may be exposed to wet environments, such as kitchens, bathrooms, or outdoor settings. Understanding this rating is crucial for ensuring that devices operate reliably in conditions where water exposure might otherwise introduce risks or cause failure.
