• About SMB Series

SMB connectors are semi – precision, subminiature devices that provide repeatable electrical performance to 4 GHz. The SMB family of connectors provide a means of quick-connect and disconnect through a snap-on type coupling.

Its smaller physical size and snap-on coupling make the SMB an ideal general purpose connector where packaging density, ease of mating / unmating and economy are prerequisites. Crimp, clamp and receptacle types are available in right angle , printed circuit board and straight body styles.

Typical applications for SMB connectors are telecommunications, test equipment, instrumentation and GPS .
