Salt spray corrosion is a common and destructive form of environmental corrosion that poses significant challenges for equipment and connectors. When exposed to high concentrations of salt spray or enclosed environments, devices require connectors with high salt spray corrosion resistance.
Lingke Electric’s YM series of industrial waterproof connectors, available in various sizes such as M20 and M24, offer exceptional resistance to salt spray corrosion. These connectors, including power connectors, multi-core and RJ45 signal connectors, and USB data connectors, are suitable for outdoor and corrosive working environments.
Understanding Salt Spray Corrosion:
Salt spray corrosion primarily affects metallic connectors and their metal components. Salt spray consists of tiny droplets containing sodium chloride, which disperse in the air and release countless chloride ions. These ions penetrate the metal’s protective layers and initiate electrochemical reactions, leading to the formation of electrolyte films and corrosion on the connector’s metal surface.
The Importance of Salt Spray Corrosion Resistance:
Choosing connectors with superior salt spray corrosion resistance is essential for maintaining reliable connections and ensuring the normal operation of equipment in corrosive environments. Lingke Electric’s YM series excels in this regard, providing robust protection against salt spray corrosion.
Key Factors Enabling High Salt Spray Corrosion Resistance:
Lingke Electric, as a global industrial waterproof connector manufacturer, excels in developing highly reliable industrial connectors. The YM series is a high-quality product that focuses on salt spray corrosion resistance performance.
It is currently widely used in salt spray corrosion-prone areas such as outdoor environments and marine vessels. Let’s discuss how the YM series achieves high salt spray corrosion resistance.
Housing Material:
Salt spray corrosion primarily affects the metallic material of connectors or the metallic parts of connectors. The housing of the YM series industrial waterproof connectors is made of PBT high-performance outdoor engineering plastics, which have high salt spray corrosion resistance. Additionally, the connectors have different levels of high protection ratings, such as IP65/IP67/IP68, which can isolate the atmosphere and protect the internal metal components of the connectors.
Internal Terminals:
Even with the external high salt spray corrosion-resistant PBT high-performance outdoor engineering plastics, the internal terminals may be temporarily exposed to salt spray corrosion environments during insertion and separation or other occasional situations. If the terminals have certain salt spray corrosion resistance, complete protection against salt spray corrosion can be achieved.
The YM series internal terminals are treated with nickel-plated gold surface processing, meeting the requirements of salt spray tests for over 48 hours. This ensures that the connector contact parts have strong corrosion resistance and can withstand exposure to salt spray environments during the insertion and separation process without concerns.
Salt Spray Testing:
Test data is the most reliable indicator of a product’s salt spray resistance. Salt spray testing is an environmental test that evaluates the corrosion resistance of products or metal materials by simulating salt spray environments created by salt spray test equipment. Lingke Electric’s UL and TUV authorized laboratories conduct tests using two methods: neutral salt spray (NSS) and acetic acid salt spray (CASS).
Currently, the salt spray requirement for the YM series industrial connectors is ≥48H, and users can also customize products with higher salt spray resistance requirements of over 96 hours. Therefore, the entire YM series can fully meet the salt spray resistance requirements for various user scenarios.
Conclusion:
The YM series industrial waterproof connectors from Lingke Electric demonstrate outstanding salt spray corrosion resistance. Through the use of high-performance outdoor engineering plastics for the housing, gold-plated internal terminals, and rigorous salt spray testing, these connectors reliably protect equipment in corrosive environments.
