Ingress Protection (IP) rating is a standardised measure defined by the International Electrotechnical Commission(IEC) under standard 60529 to classify the degree of protection that an enclosure provides against the ingress of solid objects, dust, accidental contact, and water.
The rating consists of two digits: the first digit (0-6) indicates the level of protection against solid particles, with higher numbers offering better protection, while the second digit (0-9) specifies the protection against liquid, with higher numbers indicating greater resistance.
For example, an IP67 rating means the enclosure is dust-tight and can withstand immersion in water up to 1 meter deep for 30 minutes. IP ratings are crucial for ensuring the reliability, safety, and robustness of electrical and electronic devices in various environments.
