What is the practical significance of access control reader durability ratings?
Access control readers, especially those used outdoors, are continuously exposed to different environmental conditions and physical stress. Durability requirements naturally vary depending on the installation location. Even indoor readers may encounter challenging environments, such as moisture or oily dust in factories, or vandalism in schools and public spaces.
How durability ratings guide the choice of access control reader
Standardized IP and IK ratings simplify comparing different readers and help ensure you select the right product. The IP rating indicates the device’s ability to resist environmental factors like dust and moisture, while the IK rating reflects its resistance to both intentional and accidental impacts. Together, these ratings confirm that a device is suited to withstand the demands of its installation site.
The selection should be based on the specific risk level at the installation site. Choosing a more robust reader reduces lifecycle costs. A durable device is less likely to fail, requires fewer repairs, and will last longer before needing replacement.
What do durability ratings mean?
IP rating means protection against dust and water
IP ratings specify how well a device resists dust and moisture. The first digit indicates dust protection, while the second shows moisture resistance. For example, IP67 means the reader is completely dustproof (6) and can withstand temporary immersion in water (7).
Examples of common IP ratings and what they mean for moisture resistance
- IP54: Suitable for indoor use; can withstand light rain.
- IP65: Intended for outdoor use; resists water jets.
- IP67: Built for tough environments; survives even temporary immersion in water. In practice, IP67 is the most reliable choice for outdoor installations and gates that face heavy weather, where moisture risks are high. Outdoor readers may be exposed to constant rain, melting snow and ice, floodwater, or prolonged condensation. An IP67-rated reader can also withstand cleaning.
Dust resistance
For dust protection, ratings of 5 and 6 indicate that the device resists dust entry. A rating of 6 means it is completely dustproof, while a rating of 5 allows minimal dust inside, but not enough to affect performance. Lower dust ratings are uncommon in access control readers.
What does IP6 level dust tightness mean in practice?
- No dust enters under any conditions.
- Protects against fine dust, sand, concrete dust, flour dust, and metal dust.
- Ideal for industrial settings, outdoor entrances, and construction sites.
- Internal components remain protected from abrasive dust.
- Prolongs the life of the electronics.
IK rating means mechanical impact resistance
The IK code measures how much impact energy, in joules, the device can withstand. Typical durability ratings are IK09 and IK10.
- IK09 = 10 Joules
- IK10 = 20 Joules
IK10 withstands twice the impact energy of IK09. In practice, the difference means, for example:
- IK09: Handles everyday knocks and bumps, such as a nearby door striking the reader.
- IK10: Engineered for demanding environments and areas prone to vandalism, where devices may be kicked, hit, or attacked with tools.
Where are IK ratings especially important?
IK ratings are crucial at entrances with high foot traffic, where the risk of accidental or deliberate impacts is greater. In shopping centers, schools, and public transit hubs, vandalism such as kicking is possible. In industrial locations, including warehouses, loading docks, and production areas, heavy equipment or carts may impact the devices.
How are durability ratings tested in practice?
IK rating testing (mechanical impact resistance)
IK ratings are defined by standard EN 62262. In testing, a device is struck with a specified amount of energy (measured in joules) using either a falling or swinging object. Manufacturers do not conduct these tests themselves; instead, independent laboratories perform them, giving buyers trustworthy data on the product’s true durability.
During the impact test, the device is hit with a test hammer or a drop device. The impact energy matches the IK level:
- IK09 is 10 Joules,
- IK10 is 20 Joules.
The test uses a spherical steel object with a specific weight and drop height. Several impacts are applied from different angles and to different parts of the device.
After testing, the device is checked for physical damage such as cracks, detached parts, or dents. Its functionality is also tested to ensure it still operates correctly. This process demonstrates the reader’s ability to withstand real-world mechanical stresses, such as kicks, hits, or attempts to forcibly remove the device.
IP rating testing (dust and water resistance)
IP ratings are evaluated according to standard IEC 60529, ensuring that dust and water do not penetrate the device during normal use.
For dust testing, the device is placed in a sealed, vacuumed chamber. The vacuum encourages dust to enter the device. Usually, talc is used and the test lasts several hours. After the test, the device is opened and inspected.
The method for water resistance testing depends on the rating.
For IPX6, the reader is sprayed from multiple angles with a high flow rate, simulating heavy rain, pressure washers, or waves.
For IPX7, the reader is submerged to a depth of one meter for 30 minutes. No water should enter during or after the test. This confirms the reader can operate in rain, snow, during cleaning, or in outdoor conditions, without short-circuits or malfunctions.
Summary
- Durability ratings are not minor technical specifications — they are essential for a reader’s long-term reliability.
- Public and demanding environments clearly benefit from IK10-rated readers.
- IP67 is the safest choice for outdoor installations, offering complete resistance to dust and moisture.
