What is ipx4?

IPX4 is a rating from the Ingress Protection (IP) classification system, indicating a device's resistance to water. Specifically, an IPX4 rating means that the device is protected against splashes of water from any direction. This rating does not indicate dust resistance, as the "X" denotes that the dust protection level is not specified. Devices with an IPX4 rating are suitable for use in environments where they may be exposed to moisture but are not waterproof.
