SMB subminiature connectors are designed for applications from DC up to 4 GHz. The SMB snap-on mechanism provides a fast and reliable connection for applications with high packing densities. SMB connectors are used for the internal wiring in fixed and mobile communication equipment as well as in automotive applications.The subminiature connectors Series SMB, SMC, SMS have the same basic design. They only differ with regard to their coupling mechanism.
SMB connector line offers a cost effective solution for digital cellular PCN, Global Positioning System (GPS) and wireless LAN system.
