Under IEC 60529, an IP rating describes how well an enclosure resists solids and liquids. In IP64, the first digit, 6, is the highest solids rating: the enclosure is fully dust-tight, with no ingress of dust at all. The second digit, 4, covers liquids: the device is protected against water splashing against it from any direction.
This makes IP64 a strong fit for dusty environments and sheltered outdoor or splash-prone locations, where airborne particles must be kept out but full immersion is not expected.
What IP64 does not cover:
- Pressurised water jets (that is IP65 or IP66)
- Temporary or continuous immersion (IP67 or IP68)
Enclosure rating matters because a LoRaWAN sensor often runs for years in one spot. Choosing a rating that matches the real conditions, dust, splashes, jets, or submersion, protects the electronics and avoids premature failure. The devices below carry an IP64 rating; compare neighbouring ratings if your site is wetter or harsher.

Frequently asked questions
What does IP64 mean?
Under IEC 60529, the first digit 6 means the enclosure is dust-tight, with complete protection against dust ingress. The second digit 4 means it is protected against water splashing against the enclosure from any direction.
Is IP64 waterproof?
No. IP64 protects against splashing water from all directions, but not against water jets, heavy rain under pressure, or immersion. For submersion you need IP67 or IP68; for jets, look at IP65 or IP66.
Where are IP64 devices suitable?
IP64 suits dusty indoor and sheltered outdoor environments, such as workshops, agricultural buildings, and equipment exposed to splashes, but not washdown jets or flooding.
