Understanding IP Protection Levels: How to choose the right security device for you?

In the field of industrial automation, various safety controllers and sensors play a crucial role in the protection of personnel safety. These devices not only need to have high-precision safety and reliability, but also must adapt to a variety of harsh working environments. Therefore, the IP protection level becomes an important criterion to evaluate whether these products are reliable in actual use.

This article will analyze the IP protection level of security sensors, so that you can have a deeper understanding of the impact of this standard on product applications.

IP protection level

The IP Protection scale, which stands for Ingress Protection, was developed by the International Electrotechnical Commission (IEC) to measure the intrusion protection of electrical equipment enclosures against solid substances and liquids.

The level of IP protection level consists of two numbers:

The first digit indicates the protection capability of the device against solid substances, ranging from 0 to 6. The higher the number, the higher the level of protection, which can effectively prevent smaller particles from entering the device.

The second digit indicates the device's ability to protect against liquids, ranging from 0 to 9. The higher the number, the higher the level of protection and the ability to withstand a higher degree of liquid pressure, water depth or jet pressure. The degree of tightness of electrical appliances against moisture and waterproof entry, the larger the number, the higher the level of protection.

For example, according to the above criteria: IP67 rating equipment means that the equipment has complete protection against solid substances (level 6) and can withstand short periods of immersion in water (level 7). In the construction machinery working environment, dust, heavy rain, mud, etc., may lead to serious erosion of the mechanical controller, if the controller does not have sufficient protection levels, these factors may affect the stability and service life of the controller.

Expansion of the protection level

Based on the IEC 60529 standard, the German standard DIN 40050-9 extends the IP code of the letter "K" to define the class IP69K, which not only requires products to be able to withstand high pressure and high temperature washing, but also the ability to withstand high pressure and steam cleaning. To ensure that products with an IP69K rating provide effective protection against the penetration of high pressure, high temperature water and dust, a series of rigorous tests must be passed.

Safety protection of Bytorent

In order to meet the growing safety needs of the market and customers, as well as the safety requirements in harsh industrial environments, Badoun continuously upgrades its products, expands its safety product line, and introduces a series of safety sensors: safety interlock switches and non-contact safety switches.

Compared with the conventional safety switch, the safety interlock switch has IP67 level protection standard, and its operating temperature range extends to -25℃~80℃; Ensures better safety and durability in extreme environments. Therefore, Bytorent safety interlock switches are particularly suitable for applications in high-demand industries such as automated production lines, robot production lines and hazardous test areas.

The Shield-EN series non-contact safety switch, with IP69K level protection standards, high temperature and cold resistance, operating temperature range of -25℃~70℃/90℃, can be applied to a variety of harsh environments, such as chemical production, oil exploration, CNC machinery, etc., to provide a reliable solution for a variety of extreme environment applications.

The company focuses on the application of innovative safety technologies to provide a solid security guarantee for the advancement of industrial automation. We not only supply high quality products, but also provide customized service and support to ensure that customers can effectively meet a variety of security challenges.
