IP66 Cabinets & Enclosures

SAC equipment cabinets carry a rating of IP66, keeping your electronic equipment dust-tight and dry in the strongest storms to provide maximum security against equipment damage.

Ingress Protection (IP) tests rate electronic enclosures based on their ability to protect equipment from materials that can damage electronics. The first number refers to the level of protection against solid foreign objects, and the second number refers to the level of protection from water and other liquids.
