A truly rugged industrial device is engineered, from the ground up, to operate in the most extreme hostile environments. The industrial engineering design is not only limited to the external housing, but includes internal components, special coatings, sealants, and other design features allowing computers to be exposed to extreme humidity, dust, temperatures, vibration and shock. Included in the mix is a class of products manufactured explicitly for use in hazardous or explosive environments.
IP (Ingress Protection) ratings are standards for electrical enclosures. The rating refers to the equipment's ability to permit solids and liquids to penetrate the computer's enclosure. The protection standards are defined by the IEC (International Electrotechnical Commission). A mobile computer's IP Rating is expressed as a two-digit number (Example: IP-66). The first number designates protection from solids, while the second number designates protection from liquids. Please refer to the table for specific IP rating information.
