Ingress Protection (IP) is a rating system used to describe the level of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The IP code consists of two numbers, the first one indicating protection against solids and the second one against liquids. The higher the numbers, the higher the protection level. For example, IP68 means complete protection against dust and protection against long periods of immersion in water.
