IP67

What is IP Rating?

An IP Rating, also known as an Ingress Protection Rating, is an international standard that was developed by the International Electrical Commission (IEC 60529), used to classify the rate of protection of electronic product protections against foreign bodies such as dust, water and intrusion of objects, including accidental contact with foreign bodies.

IP Ratings consist of the letter "IP", followed by two digits that indicate the classified protection level. The first digit following "IP" refers to the level of protection an object has against solid foreign objects such as dust and fingers, to protect the hazardous parts of the electrical component, such as electrical semiconductors. This rating is rated from level zero to six (0-6), where zero (0) means it is not protected, and six (6) is the highest level of rating against the ingress of dust. Dust and solids are measured by particle sizes ranging from 50mm, 12.5mm, 2.5mm, 1.0mm particles, and can be compared to wind-blown dust, light fibers, and other air-borne solid objects. Level 6, the highest level of solid-ingress protection, is also known as “dust-tight”.

The second digit of an IP Rating refers to the rate of protection of the internal electronic component against water ingress. This can range from light water sprays, up to more powerful and larger volumes of water, even submersion in liquid. Protection against water ingress can vary from zero to nine (0-9). The lowest level of water ingress protection indicates that the electrical component is protected from light water jet sprays from any direction. IP Ratings waterproof tests are conducted in controlled environments with a 12.5mm or 6.3 mm nozzle. The water pressure is then altered and applied to certify various levels of water tightness.

What Does IP67 Mean?

IP67-Rated protection provides high-level protection due to their high water and dust ingress protection ability.

The first digit of IP67 (6), is the highest level of protection against solid ingress, such as windblown dirt and other airborne solid materials that are invisible to the naked eye. Combined with their high-level water-ingress protection indicated by the second digit (7), IP67-rated protection can withstand water hose and jet sprays and can sustain momentary water immersion in depths of 150mm to 1000mm up to 30 minutes maximum. IP67-rated devices are guaranteed to function in indoor, outdoor, w and demanding industrial and commercial settings.

Benefits of IP67

Excellent Dust Protection: The first digit "6" in IP67 represents the highest level of protection against dust ingress, completely blocking any size of dust and solid particles from entering. This effectively safeguards the internal electronic components from dust and contamination.

Superior Water Protection: The second digit "7" in IP67 indicates the ability to withstand temporary water immersion, whether it's high-pressure water jets or brief submersion, without causing damage to the internal components.

All-Weather Suitability: IP67-rated protections can operate reliably in indoor, outdoor, and harsh industrial environments, able to withstand the impact of various adverse environmental factors, significantly improving the device's reliability and lifespan.

Widespread Applicability: Due to the outstanding protection performance, IP67-rated protections are widely used in electronic equipment required to function in demanding environments, such as industrial automation, outdoor surveillance devices, medical equipment, and more.

Enhanced Safety: The comprehensive protection also better safeguards users and equipment from accidental contact or ingress of hazards.
