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-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 hight angle, printed circuit board and straight body
styles.
Typical application for SMB Connectors are telecommunications, test
equipment, instrumentation and GPS.
