IP / IK protection classes
The specification of the degree of protection of an enclosure is determined by the abbreviation IP (Ingress Protection) and a two-digit code number. The first digit has two meanings: Protection for people and equipment. The second digit has only one meaning: protection against water. As a standard, almost all ROLEC enclosures are designed in protection class IP 65 and IP 66 and thus meet a high industrial standard for series products: that is, the enclosure offer protection against the ingress of water and dust. In addition, many of the ROLEC standard enclosures made of aluminum and polyester can be designed with IP 67 and IP 69K degrees of protection on request.
