FAQ
What does an IP66 rating mean?
IP66 is a protection rating defined by the IEC 60529 standard. It consists of two digits:
The first digit “6” means the enclosure is completely dust-tight, offering full protection against solid particles.
The second digit “6” means the enclosure can withstand powerful water jets from any direction, with no water ingress.
This rating ensures excellent protection in harsh indoor and outdoor environments, including rain, washdown, and dusty industrial settings.
How is IP66 different from IP65 or IP67?
Rating | Dust Protection | Water Protection | Typical Use Case |
| IP65 | Full | Low-pressure water jets | Light outdoor use, machine panels |
| IP66 | Full | High-pressure water jets | Harsh industrial, outdoor environments |
| IP67 | Full | Temporary immersion | Underground, marine applications |
| IP66 offers stronger water protection than IP65 and is a good balance for most industrial outdoor needs. | |||
Can IP66 enclosures be used outdoors?
Yes, IP66 enclosures are ideal for outdoor use. They are designed to resist:
Rain and water spray
Dust and sand
UV exposure (if coated properly)
Temperature variations
For long-term outdoor performance, we recommend enclosures made of stainless steel or UV-stabilized plastic, with proper gasketing and corrosion-resistant hardware.
Can I customize an IP66 enclosure for my application?
Absolutely. At Hofengfab, we specialize in custom IP66 metal enclosures. Customization options include:
Cutouts for switches, fans, cable glands
Custom dimensions and mounting systems
Branding (laser engraving or silk screen)
Hinged doors, viewing windows, double-door access
Internal accessories: DIN rails, terminal blocks, mounting plates
Send us your design files or sketches — our engineers will guide you through the process.
What standards and certifications should I look for?
In addition to IP66 compliance (IEC 60529), many industries require:
CE Marking – For European market compliance
RoHS Compliance – Restriction of hazardous substances
UL or NEMA Ratings – For North American applications
ISO 9001 Manufacturing Standards – For consistent quality control
At Hofengfab, all our enclosures are manufactured under ISO 9001 and can meet CE/RoHS standards on request.
How can I be sure the enclosure is truly IP66?
We conduct ingress protection testing on representative units using:
Dust chamber testing (per IEC 60529)
Water jet testing (powerful nozzles simulating real conditions)
Visual and leak inspections
Test reports can be provided for project documentation or regulatory requirements.
Do you ship IP66 enclosures internationally?
Yes. Hofengfab ships to over 20 countries across Europe, the Middle East, North America, and Southeast Asia. We offer:
Flexible logistics (DHL, FedEx, air freight, sea freight)
Export documents (packing list, CO, invoice, CE declaration, etc.)
Multilingual support and technical drawings
Lead time is typically 7–15 working days, depending on customization level and quantity.
What materials are IP66 enclosures made from?
Polycarbonate (PC) – Lightweight, impact-resistant, UV-stable.
ABS Plastic – Cost-effective, good mechanical strength.
Stainless Steel (e.g., 304 or 316) – Corrosion-resistant for extreme conditions.
Aluminum – Lightweight yet durable, often used in electrical cabinets.
Selection depends on factors like chemical exposure, temperature, and structural needs.
