Understanding IP67: A Guide to Ingress Protection Ratings for Electrical Enclosures
Published on
August 16th, 2024
Ensuring the protection of your devices from external elements is extremely important. Thankfully, various rating systems exist to help you choose the right enclosure for your needs. One of the most commonly used systems is the IP rating system.
What Does IP67 Mean?
An IP67 rating means that an electrical enclosure provides a high level of protection against both dust and water. Devices with this rating are shielded from the harmful effects of these elements, making the IP67 rating common in consumer electronics like smartphones and industrial applications where robust protection is necessary.
IP67 enclosures are designed to be dust-tight, preventing dust particles from entering and potentially harming the device's internal components. Additionally, these enclosures offer substantial water resistance and withstand anything from hose-directed sprays to temporary submersion in water. This makes IP67-rated enclosures a solution for those looking to safeguard their devices in challenging environments.
Understanding the IP Rating System
The IP rating system, established by the International Electrotechnical Commission (IEC), is an international standard for the degree of protection provided enclosure against solid objects and liquids. These two factors are important in ensuring the safe and reliable operation of electronic devices.
-Solid Object Ingress: refers to the enclosure's ability to prevent solid particles from entering. These particles range from large objects like tools or human hands to fine dust or sand. Particle ingress can cause significant damage to a device's connectors, printed circuit boards, and other components, potentially impairing its functionality.
-Liquid Ingress: refers to the enclosure's ability to prevent water from entering. Water ingress can occur due to various factors, such as accidental spills, splashes, or submersion. Since liquids pose one of the most significant risks to electronic devices, ensuring the right level of protection is critical.
Decoding the IP Rating
The IP rating system uses a two-digit code to specify the level of protection an enclosure offers:
-First Digit (Solid Protection): This digit indicates how well the enclosure guards against solid objects. The scale ranges from 1 to 6, with 1 offering minimal protection and 6 providing complete protection against dust and other small particles.
-Second Digit (Liquid Protection): This digit indicates the level of protection against liquids, ranging from 1 to 9. A rating of 1 protects against light-dripping water, while a rating of 9 means the enclosure can withstand high-pressure and temperature water jets.
To find the ideal enclosure for your needs, match the protection level required for your device against the IP rating. By understanding the specific threats to your device and comparing them to the enclosure's IP code, you can ensure your device is well-protected against potential hazards.
Here’s some of the products that have the IP67 Rating:
1. PowerCore series of engine controllers; MPC20, MPC10, and TEC-10.
2. Tactile button PV displays; 380,450,480, and 780B.
3. Edge to Edge PV displays; 500, 700, 1100, and 1200.
4. PDM Series expansion modules.
5. U Controls Series expansion modules.
The IP67 rating is a testament to an enclosure's ability to provide exceptional protection against dust and water. Whether you're safeguarding industrial equipment or personal electronics, choosing an enclosure with the right IP rating is essential for maintaining the longevity and performance of your devices. By understanding the IP rating system, you can confidently select an enclosure that meets your protection requirements, ensuring your devices remain safe and operational in any environment.
