Photovoltaic cell module connector

SMK Corp. has announced that its photovoltaic cell module connector for power generation systems has earned the recognition from Underwriters Laboratories Inc. (UL) for the U.S. market.

Photovoltaic generation systems comprise multiple photovoltaic cell modules connected with cables and are installed on rooftops. For connection of cables, relay connectors are used. These connectors are installed outdoors, so they are required to be waterproof and resistant to weather. Workability during installation is also important.

The connector is designed to relay cables emerging from photovoltaic cell modules. Under such circumstances and with our eyes focused on the big potential for further expansion lying in this market, we developed the "photovoltaic cell module connector" excellent in contact performance, waterproofing property and workability, and recently earned UL recognition.

Having earned the TUV certification for European markets, the UL recognition will enable SMK to evolve and further spread marketing activities in the North American market. The device offers voltage and current rating of 30A and 1,000V under TUV specification, and 25A and 300V under UL standard.

The photovoltaic cell module connector provides high contact performance with its proprietary multi-point contact system. It also offers easier and tool-free application of waterproofing property around cables due to the waterproofing structure (top and bottom cover system). The connector also has locking mechanism that cannot be manually undone.

In addition, the product is capable of handling a large current and uses copper alloy spring material for electrical conductivity. The connector also uses a plastic material with excellent weatherability and flame retardancy (UL94V-0) and is RoHS-compliant.

The connector operates at -40C to +90C. Production capacity is 500,000 units/month. Sample price is 500 yen/pair ($5.45), cables not included.
