IP68 vs. IP69 Waterproof Ratings
| Item | IP68 | IP69 |
|---|---|---|
| Perlindungan Debu | Level 6 – Dust-tight | Level 6 – Dust-tight |
| Perlindungan Air | Long-term immersion (static water) | High-temp & high-pressure water jets |
| Test Conditions | ≥1 m depth, ≥30 min, ambient water | 80℃ water, 80–100 bar, 14–16 L/min, multi-angle spray |
| Aplikasi | Diving gear, underwater sensors, humid devices | Car wash, food processing, industrial machinery |
| Design Focus | Static sealing (O-rings, compression) | Dynamic sealing + heat-resistant materials |
Which IP Rating Fits Your Needs?
| Scenario | Best Choice | Mengapa Ini Penting | Typical Products |
|---|---|---|---|
| Everyday use / Rain | IP67 / IP68 | Protects against rain & splashes | Phones, Smartwatches |
| Diving / Underwater | IP68 | Safe for long immersion | Diving gear, Underwater sensors |
| Food & Medical Hygiene | IP69K | Handles hot steam cleaning | Kitchen & Medical equipment |
| Heavy-duty Cleaning | IP69K | Withstands high-pressure jets | Machinery, Car wash panels |
| Marine / Coastal use | IP68 + Anti-corrosion | Extra salt & corrosion resistance | Marine radars, Dockside devices |
Best Material Options for Waterproof Enclosures (IP68/IP69)
| Bahan | Key Advantages | Best For |
|---|---|---|
| Baja Tahan Karat 304 | Durable, weather-resistant, cost-effective | Outdoor equipment, EV chargers |
| Stainless Steel 316 | Superior corrosion resistance, seawater & chemical protection | Marine, chemical & IP69 enclosures |
| Aluminum Alloy 6061 | Lightweight, easy to machine, economical | Automotive parts, portable housings |
Quick Tip 💡
-
Choose 316 Stainless Steel untuk IP69 enclosures (handles high-pressure jets + chemicals).
-
Use Aluminum Alloy with anodizing ≥15 μm for lightweight designs under high-pressure cleaning.
Material Selection Decision Guide
-
First, check the environment:
-
If it’s seawater, high salt spray, or chemicals → go with 316 stainless steel (best balance of cost and performance) or titanium alloy for extreme demands.
-
If it’s freshwater or normal outdoor conditions → choose 304 stainless steel atau anodized aluminum alloy.
-
-
Next, consider weight sensitivity:
-
For mobile equipment or aerospace → paduan aluminium (6061-T6) is the right choice.
-
For fixed equipment → baja tahan karat is preferred (lower cost and easier maintenance).
-
-
Finally, match the IP protection level:
-
IP69 (high-temp, high-pressure cleaning) → 316 stainless steel (corrosion + jet resistance) or surface-treated aluminum alloy (coating must be tested for heat resistance).
-
IP68 (long-term immersion) → 316 stainless steel for marine, 304 stainless steel for freshwater, or titanium alloy for deep-sea.
-
IP65–IP67 (splashing or short-term immersion) → 430 stainless steel (low cost) or 5052 aluminum alloy (lightweight).
