If you have ever used an aluminum glass door lock, you must have encountered the situation of the lock being damp, the fingerprint is unstable or the power is lost after heavy rains. This is a common “pain” that makes many people have to change the lock after only a few months of use. To completely overcome this problem, OSUNO applies international waterproof standards such as IPX5, IP65 and IP68, helping the lock operate stably in.
What is IPX5? – Popular waterproof standard for outdoor aluminum door locks

IPX5 is a waterproof standard that allows the device to withstand low-pressure water jets from any direction for a certain period of time. This means that an IPX5 door lock can be installed on a balcony, hallway or area with rain splashes, while still ensuring that water does not penetrate the circuit board.
OSUNO aluminum lock lines such as OSN-2601 are designed with:
- Rubber gasket seals tightly around the edge of the lock body, preventing water and dust from entering the circuit.
- The circuit board is coated with nano moisture-proof layer, ensuring stability even when operating in drizzly or high humidity weather.
- Solid aluminum alloy body, rust-free, impact resistant.
=> With IPX5, OSUNO aims at a practical security solution for aluminum doors – much more sustainable and economical than higher levels but not necessary in civil conditions.
Comparing IPX5, IP65 and IP68 – Differences in protection and applications
| Standard | Water resistant | Dustproof | Suitable application |
| IPX5 | Withstands direct water jets at moderate pressure | Have | Aluminum doors, balconies, covered areas |
| IP65 | Completely dustproof, resistant to strong water jets | Have | Area of heavy rain, exposed to the outdoor environment |
| IP68 | Absolutely dustproof, can withstand deep immersion in water | Have | Coastal construction, harsh areas |
Depending on the needs of use, users can choose the appropriate standard. IPX5 is a good balance between protection, aesthetics and investment costs, while IP68 is usually for harsher environments.
Some waterproof techniques applied by OSUNO for IPX5 lock line
OSUNO does not pursue “the higher the index, the better”, but focuses on the actual level of protection needed for Vietnamese
- IPX5 makes the lock more durable, saving maintenance costs.
- Tightly sealed, waterproof design, resistant to tropical humid environments.
- Keep the fingerprint sensor and circuit board working properly, even in light rain or frost.
Lines like the OSN-2601 are typical examples – both meeting IPX5 standards and having fingerprint and card unlocking features and app control.
Conclude
With the tropical monsoon climate of Vietnam, the IPX5 waterproof standard is the most reasonable choice for aluminum door locks. OSUNO locks that meet the IPX5 standard are not only effective in waterproofing but also ensure durability, aesthetics and stable operation for many years, bringing peace of mind and saving maintenance costs for users.
