Preface
"I am a supporting role, a minor supporting role." Audiences who have watched the recently popular movie "Nezha 2" may have been amused by this line. "Supporting role" seems to give people the impression of being insignificant. In the manufacturing field, in a device that contains hundreds or even thousands of parts, the small connector, which seems to be a supporting role, actually plays a very critical role.
Many luxury devices worth millions of dollars eventually break down due to malfunctions. Engineers check and check and sometimes find that the problem is the easily overlooked component - the industrial connector. A large part of this is caused by waterproof failure and waterproof performance defects.
Comparison of waterproof levels of industrial connectors: IP65&IP67&IP68&IPX9K
For industrial connectors, the commonly used waterproof grades are IP65, IP67, IP68, and IPX9K. (The first digit 6 is the dustproof grade, and the second digit is the waterproof grade). The differences between them are shown in a table.
IP65: Protected against low-pressure water jets, suitable for dusty and rainy environments.
IP67: Anti-short-term water immersion, suitable for scenarios where it may be temporarily immersed.
IP68: Protected against continuous water immersion, suitable for long-term underwater use.
IPX9K: Protected against high temperature and high pressure spray, suitable for extreme industrial cleaning environments.

YM series waterproof introduction: IP68 flagship waterproof
1 Flagship configuration: IP68 waterproof
The YM series industrial waterproof connector is a high-performance waterproof connector with a full plastic shell made of SABIC's high-quality F1 grade outdoor engineering plastic. It has strong advantages such as high and low temperature resistance, vibration resistance, shock resistance, and UV resistance. The waterproof grade reaches IP68.
2 How does the YM series connector achieve high waterproofness?
01 High-performance materials: ①SABIC material shell; ②High-performance elastic silicone sealing material
02 Self-developed waterproof structure design: ①Axial and radial sealing of the sealing ring ②Spiral bayonet connection and locking structure
03 Smart manufacturing process guarantee: ① Relying on CNLINKO digital factory production, product size is high precision ② High-precision injection molding, lower surface roughness, more rigorous combination
04 Waterproof performance testing: relying on UL&TUV authorized laboratories to conduct strict inspections to meet the waterproof grade requirements
Application Case Sharing: Water Quality Monitoring System
The water quality monitoring system is a device used to detect and analyze water quality in real time. It is widely used in environmental protection, industrial production, agricultural irrigation, drinking water safety and other fields. Due to the relatively harsh application environment, the connectors required for the water quality monitoring system are industrial-grade connectors, which are more reliable and durable.
For water quality monitoring systems, power connectors and signal connectors are used. They provide power connection support and sensor signal transmission respectively. The YM series industrial connectors of CNLINKO are built with strict design and manufacturing standards to achieve IP68 high waterproof performance, which can provide stronger protection in the humid and liquid environment of water quality monitoring systems.
In addition, this series of products also has the characteristics of corrosion resistance, high and low temperature resistance (-25℃~85℃), flame retardancy, and UV resistance, which are very consistent with the technical requirements of various water quality monitoring systems.
At present, this product is also widely used in many fields such as automation equipment, electronic equipment, new energy, electromechanical equipment, mechanical equipment, instrumentation, ships, vehicle-mounted equipment, medical equipment, security, LED display, etc.
