Understanding IP68: High-Level Dust and Water Protection

IP68 Blog Cover_4

In the world of industrial automation, ensuring that equipment can withstand harsh environmental conditions is paramount. One of the most reliable measures for this is the Ingress Protection (IP) rating system. Among the various ratings, IP68 stands out as a high industry standard for dust and water protection. In this blog, we'll explore what IP68 means and highlight CIMON's nXT as a premier example of a device that meets this stringent standard.

What is IP68?

The IP rating system, developed by the International Electrotechnical Commission (IEC), classifies the degrees of protection provided by enclosures of electrical equipment. The IP code consists of two digits:

  • The first digit (6) indicates the level of protection against solid particles, such as dust.
  • The second digit (8) specifies the level of protection against water ingress.

IP68 signifies the following:

  • 6 (Dust-tight): Complete protection against the ingress of dust. No dust can enter the device, ensuring that it remains clean and operational in dusty environments.
  • 8 (Waterproof): Protection against continuous immersion in water. Devices with an IP68 rating can typically withstand being submerged in water deeper than 1 meter for a specified time, usually between 30 minutes to 1 hour, as determined by the manufacturer. 


Why is IP68 Important?

  1. Reliability: Devices with an IP68 rating are built to last. They can operate reliably in environments with high levels of dust and moisture, which are common in many industrial settings.
  2. Versatility: Whether in manufacturing plants, outdoor installations, or even underwater applications, IP68-rated devices can perform without compromise.
  3. Maintenance: The high level of protection reduces the need for frequent maintenance and repairs, saving time and costs.

CIMON's nXT: A Case Study in IP68 Excellence

CIMON, a leader in industrial automation solutions, offers the nXT series of Human Machine Interfaces (HMI), which exemplifies the best in IP68 protection. Here’s how the CIMON nXT stands out:

  1. Robust Design: The nXT series is engineered to operate in the harshest environments. Its IP68 rating means it is completely dust-tight and can withstand continuous immersion in water, making it ideal for use in extreme conditions.
  2. Advanced Technology: Equipped with high-performance processors and versatile connectivity options, the nXT series ensures seamless integration with various industrial systems.
  3. Durability: Built with rugged materials and advanced sealing techniques, CIMON's nXT series can handle physical shocks, temperature extremes, and corrosive environments, ensuring long-term durability.
  4. Ease of Use: Despite its ruggedness, the nXT series is user-friendly, with intuitive interfaces and comprehensive support from CIMON’s technical support team.

Top 5 Industries Where IP68 is Crucial

IP68-rated HMIs like the CIMON nXT can be used in a wide range of industries, but here are the top five where this level of protection is especially crucial:

  1. Water and Wastewater: Ensuring reliable operation in wet and corrosive environments typical of water treatment facilities. Equipment needs to function flawlessly despite exposure to water and chemicals used in treatment processes.
  2. Oil and Gas: Withstanding harsh conditions, including exposure to oil, gas, and extreme weather in drilling and processing operations. The ability to operate in explosive and high-pressure environments is vital.
  3. Chemical Processing: Surviving exposure to corrosive chemicals and maintaining functionality in challenging environments. Equipment must resist chemical spills, splashes, and vapors without degradation.
  4. Food and Beverage: Surviving regular washdowns and exposure to liquids in food processing and beverage production facilities. Hygiene and resistance to cleaning chemicals are essential to prevent contamination.
  5. Marine and Offshore: Operating reliably in humid and salty conditions, essential for marine and offshore environments. Equipment needs to withstand continuous exposure to seawater and the corrosive marine atmosphere.



IP68 is the gold standard for dust and water protection, offering unmatched reliability and durability in challenging environments. CIMON's nXT series exemplifies the benefits of IP68, providing robust, high-performance solutions across various industries. Additionally, CIMON nXT also meets UL Type 4X and Type 12 standards, ensuring versatile and comprehensive protection. With IP68-rated devices like the CIMON nXT, businesses can be confident that their equipment will withstand the harshest conditions, ensuring operational efficiency and longevity.
