IP68 electrical enclosures provide maximum protection for electrical components in dirty and wet environments. IP68 standards in a waterproof electrical connection box ensure the protection of internal electronic components in harsh conditions. These weatherproof electrical enclosures can both be plastic or aluminum and guarantee protection for components that are fully submerged in water. There is a variety of sizes and styles depending on the applications.
IP68 Rating for Electrical Connection Boxes
IP (Ingress Protection) ratings denote the degree of protection a waterproof connection box offers from water and solid objects. This information is usually an inscription on the device. Manufacturers use this to judge whether an electronic product water seal design is effective and the extent of its effectiveness.
There are two numbers to indicate the enclosure's protection level. The first one shows protection against solid object ingress or intrusion on a scale of 0-6, and the second shows protection against water ingress on a scale of 0-8.
With the two-digit rating formula, the ‘6’ in the IP68 indicates that the enclosure is dust-tight. This is the highest dust protection level as rated by the IP system. In addition, an IP68 weatherproof connection box will protect your devices against huge gusts of wind and particles.The second digit, which is ‘8’, means that the enclosure is completely watertight even during prolonged submersion. An IP68 protects your electrical components against dripping water, splashing water, rain, hose spray, snow or submersion. It is also safe against any water penetrating a device enclosure.
IP68 Enclosure Components
The IP68 weatherproof electronics enclosures are predominantly rectangular, providing the highest protection against dust and prolonged submersion in water. For the weatherproof electrical enclosures to achieve the IP68 rating, the design of the oil and fuel-resistant elastomer O-ring seals play a major role. In addition, aluminum and plastic materials are corrosion-proof and coated with oven-cured thermosetting paint. This paint makes them scratch, shock, chemical and seawater resistant.
One O-ring seal has mating edges at the base, while the other is mounted in a slot inside the base. This special O-ring seal design facilitates the waterproofness between the base and the hood. During installation, a mounting frame with four M6 threaded blind holes should be installed in the waterproof electrical connection box to improve waterproofness.
IP68 Enclosure Sizes
The IP68 weatherproof electrical enclosures are larger than standard waterproof electrical connection boxes. The size considerations provide additional space for better cable management.
The thicker walls ensure mechanical robustness, but the fixing points are similar to standard enclosures. The locking system on the waterproof electrical connection box can either be screws or bayonets. These locking systems take minimal footprints while improving water tightness. Therefore, more enclosures can be installed in a limited space.
