Understanding the Differences Between IP68, IP67, and IP66 Weatherproof Ratings
When purchasing electronic devices, particularly trail cameras, wildlife cameras, and other outdoor surveillance equipment, you may come across IP ratings such as IP68, IP67, and IP66.
IP = Ingress Protection
These ratings, defined by the International Electrotechnical Commission (IEC), indicate the level of protection against dust and water. Understanding these ratings can help you make an informed decision when selecting a device for outdoor or rugged use.
What Do IP Ratings Mean?
The IP (Ingress Protection) rating consists of two digits:
- The first digit represents protection against solid particles like dust (0-6 scale, with 6 being the highest protection).
- The second digit represents protection against water (0-9 scale, with 9 being the highest protection).
IP68: Maximum Protection
Devices with an IP68 rating are completely dust-tight and can withstand prolonged immersion in water. Typically, manufacturers specify the depth and duration of water resistance, which is often around 1.5 meters for 30 minutes or more. This rating makes IP68 devices ideal for use in wet conditions, including swimming or accidental drops in water.
IP67: Strong, But Slightly Less Than IP68
IP67 rated devices also offer complete dust protection but can only withstand immersion in water up to 1 meter for 30 minutes. While still highly water-resistant, these devices may not handle deeper or prolonged submersion as well as IP68 rated ones.
IP66: Protection Against Strong Water Jets
Unlike IP67 and IP68, which focus on immersion, an IP66 rating means a device is protected against powerful water jets but not full submersion. This rating is suitable for outdoor equipment exposed to rain or water splashes but not meant for underwater use.
In conclusion, choosing the right IP rating depends on your intended usage. IP68 is best for deep water exposure, IP67 is suitable for occasional immersion, and IP66 is ideal for heavy rain and water splashes.
