Aluminum door locks often break down quickly because of rainwater seeping in, damp circuit boards, insensitive fingerprint sensors, and even “dead” batteries after just a few months. This is a familiar concern for users of houses facing the rain or by the sea. Now, OSUNO offers an aluminum door lock solution that meets IP68 waterproof standards – the highest protection standard today, helping the lock operate stably even when submerged in water, absolutely dustproof and durable against all harsh weather conditions.
What is IP68? The highest waterproof standard today
IP68 is the highest level of protection in the IP standard system.
- Number 6 : The device is completely dust-tight, preventing fine dust particles from entering.
- Number 8 : Can withstand continuous immersion in water at a depth of over 1m while still operating stably.
For OSUNO aluminum door locks, IP68 standard means that they are not affected by heavy rain, humidity or sea fog. Thanks to the monolithic lock body, anti-oxidation coating and circuit board, covered with waterproof glue, the product still operates smoothly after a long time outdoors.
IP65 vs IP68 Comparison – Difference in Water Resistance
Here’s a quick comparison chart to help you understand the difference:
| Criteria | IP65 | IP68 |
| Dust resistance | Completely dustproof | Completely dustproof |
| Water resistant | Withstand low pressure water jets | Withstands immersion in water ≥1m deep |
| Component protection level | High | Very high |
| Suitable environment | Indoors, covered | Coastal, harsh weather |
| Typical OSUNO line | ONS- 3320, OSN- 2602/2602A, OSN- 2603, OSN- 3326/3326A | OSN- 3321, OSN- 3323/3323A, OSN- 3328 |
Conclude:
- IP65 is suitable for indoor installation or areas with little rain.
- IP68 is the optimal choice for aluminum doors, humid or coastal areas, ensuring stable operation all year round.
Should I choose IP65 or IP68 for aluminum door system?
Depending on the installation environment, you should choose the appropriate level of protection:
- Indoor / covered balcony door: IP65 lock series like OSN-2602 or OSN-3326 is enough. Dustproof, light water jet proof, keep sensor sensitivity stable for a long time.
- Door / Rain / Coastal: IP68 lock like OSN-3321 or OSN-3323A is safer choice. Fully sealed design, waterproof rubber gasket, moisture-proof coated circuit board, durable operation even after storms.
With the OSUNO aluminum door lock system meeting IP68 standards, users no longer have to worry about water seepage, power short circuits or component oxidation – common problems of poor quality locks.
