The IP (Ingress Protection) rating system IP67 and IP68 enclosure ratings bring unique protective features to the table. Understanding how the IP system operates is the first step in making an informed choice.
Read on as the experts at SLAYSON explore their differences, similarities, and, most importantly, how to determine which rating is most suitable for your particular needs. Safeguarding your electronics against the elements is paramount, and we’re here to make the right choice for your equipment’s protection.
The universal standard for categorising the protective capabilities of electrical enclosures
Each IP rating is composed of a two-digit number, where each digit has a distinct significance. The first digit in the IP rating denotes the enclosure’s resistance to solid objects, encompassing everything from the finest dust particles to larger entities. The scale runs from 1 to 6, with 1 representing the most rudimentary protection and 6 signifying an entirely dust-tight enclosure. This digit provides valuable information about how effectively the enclosure guards against the intrusion of solid matter, a critical consideration in environments where dust or debris can compromise the functionality of electronic components.
The second digit of the IP rating characterises the enclosure’s resistance to water ingress. It’s important to note that this digit exclusively pertains to protection against water and doesn’t encompass other liquids such as oil or coolant. The rating ranges from 0 to 8, with 0 indicating no water protection and 8 showing a waterproof enclosure capable of enduring prolonged submersion. This digit informs users about the level of water resistance an enclosure offers, making it particularly vital for applications where exposure to moisture or liquid is a concern.
Combining these two digits, the IP system generates a concise yet comprehensive rating that succinctly communicates the enclosure’s protective qualities. For instance, when comparing IP65 and IP67 enclosures, an IP65 enclosure would provide less water ingress protection than an IP67-rated counterpart. This simplifies the process of selecting enclosures that align with the specific environmental challenges, ensuring that the level of protection matches the application’s requirements.
IP67 and IP68 similarities
Both options are robust choices for safeguarding electrical and electronic devices across a wide range of applications. These similarities highlight their effectiveness in protecting devices against various environmental challenges.
Here are some key commonalities between IP67 and IP68 enclosure ratings:
- Complete protection against dust and particulates
IP67 and IP68 ratings ensure that the enclosed device remains impervious to dust and other airborne particulates. This means that these enclosures will maintain a dust-tight seal even in dusty industrial settings or outdoor environments, preventing particles from infiltrating and potentially damaging sensitive electronics.
- Protection against contact by workers and small objects
IP67 and IP68 enclosures offer protection against accidental contact by workers and small objects. This feature is critical in workplaces where equipment may be exposed to human interaction or small tools or foreign objects could come into contact with the enclosure. This prevents mishaps and maintains the integrity of the device.
- Protection against dripping, spraying, and splashing water
Both ratings protect against water intrusion, including dripping, spraying, and splashing. This makes them suitable for devices used in environments where exposure to moisture is common, such as outdoor installations or laboratories.
- Protection against pressurised water jets
IP67 and IP68 enclosures can withstand the impact of pressurised water jets. This feature ensures that devices within these enclosures remain operational and safe even when subjected to powerful water streams, which can occur in industrial or outdoor settings.
- Protection against submersion
One of the most significant commonalities is the ability to withstand submersion in water. IP67 and IP68 enclosures are designed to keep the enclosed device dry even when submerged in up to 1 meter of water for a specified duration, typically up to 30 minutes. This capability makes them ideal for applications where equipment might be exposed to rain or temporary submersion.
The differences between IP67 and IP68 enclosures
The primary difference between these options is the submersion depth and duration:
- IP67: Rated for submersion at a depth of 1 meter for up to 30 minutes.
- IP68: Rated for submersion at least 1 meter deep for up to 30 minutes, with additional depth and duration specified by the manufacturer.
While IP67 and IP68 enclosures can withstand submersion in water, the IP68 rating offers more flexibility by allowing manufacturers to specify extended submersion depths and durations beyond the baseline 1 meter for 30 minutes. This provides greater assurance for applications that require more prolonged or deeper submersion protection.
Choose SLAYSON for a NEMA 6P Enclosure
IP67 and IP68 enclosures are suitable for most typical outdoor scenarios. Nevertheless, if your device is expected to endure prolonged submersion exceeding 1 meter in depth, opting for an IP68 enclosure is advisable.
If extended submersion is not a concern, an IP67 enclosure often presents a more cost-effective alternative than IP68 enclosures. View the full range of options available at SLAYSON and let our experts help you make the right choice today.
