IP68 is an Ingress Protection (IP) rating that signifies a high level of protection against dust and water for electronic devices. The "IP" in IP68 stands for Ingress Protection, with the "6" indicating that the device is dust-tight, meaning it is impervious to dust as tested and certified on a specific scale. The "8" in IP68 denotes that the device is protected against submersion in water up to a defined depth and time duration, typically up to 1.5 meters deep for 30 minutes. This rating is common in today's market and is ideal for devices that need to withstand exposure to dust, sand, dirt, and temporary submersion in water.
