What is the maximum allowed object size for an IP2X rating?

An IP2X rating refers to an ingress protection classification that signifies a degree of protection for electrical equipment against solid foreign objects. Specifically, the first digit in the IP code denotes the level of protection against the intrusion of solid objects.

For an IP2X rating, the maximum allowed size of any object that can effectively pass through the protective enclosure is 12.5 millimeters. This size corresponds to a human finger, thus indicating that the enclosure is designed to prevent fingers and similar-sized objects from entering while allowing smaller objects to pass through. Therefore, this rating confirms that while the equipment is reasonably protected against larger solid objects, it does not provide comprehensive protection against smaller items.

This understanding of the IP rating system is crucial for assessing the safety and suitability of electrical enclosures in various environments, ensuring that only appropriately sized objects can enter the protected area, ultimately contributing to user safety and equipment longevity.
