Sumitomo Connector Classification

• Sealed Connectors
• Unsealed Connectors
• High-Frequency Connector
• Ethernet Connector
• US series

Sealed, unsealed and US series connectors are widely utilized in our custom wire harnesses due to their reliability and compatibility. These connectors have gained popularity among our customers not only because of the brand reputation but also because we can provide them with better alternatives from the Chinese market.

Many of these connectors have equivalent replacements available in the Chinese market that offer several advantages. Firstly, they come at more competitive prices compared to their original counterparts, allowing our customers to save on costs without compromising quality. Additionally, these Chinese replacements often boast shorter lead times, ensuring faster delivery and reducing production delays for our clients.

Furthermore, it is important to note that the quality of these Chinese replacements is on par with the original brands. Through rigorous testing and strict quality control measures implemented by manufacturers in China, these connectors meet or even exceed industry standards. This ensures reliable performance and durability for various applications.

By offering our customers suggestions for using Chinese replacements alongside well-known brands like Sealed and US series connectors, we aim to provide them with a wider range of options tailored to their specific needs. Ultimately, this allows us to deliver cost-effective solutions without sacrificing functionality or dependability in our custom wire harnesses.

How to Choose the Correct Connectors?

• To select a suitable connector, please consult our sales staff about the operating environment, mounting conditions, and other information (e.g. unsealed type for indoor compartment use, sealed type for engine compartment use).
• The specifications and performance of a connector may significantly vary depending on changes in variable elements in the operating environment, such as the number of ways, wire size, ambient temperature, etc.
• For how to remove the terminal or details please consult with our sales staff when requesting applicable tools.
• Some connector series require special attention during circuit checks, etc. For example, dedicated circuit check jigs must be used for the “SL series" and “SL sealed series."
• Although some connector specifications include drawings showing mating support, these drawings are provided only for reference. The manufacture of mating parts is not possible without consideration of dimensional tolerances, etc.
• Before using the product, please obtain a “connector drawing" or “Specifications" from our sales staff. Please contact our sales staff for details.
