RF Coaxial Connectors SSMB/SSMC Introduction This range of 50 ohm microminiature radio frequency connectors is suitable for both military and commercial equipment operating at frequencies up to 4 GHz (SSMB) and 12.4 GHz (SSMC). They provide a choice of Snap-on (SSMB) or Screw-on (SSMC) and are available for a wide range of flexible cables. SSMC connectors are used where a positive mechanical engagement is required and where space permits the use of torque wrenches. SSMB connectors are quick disconnect versions of the SSMC and are used in applications where limited space prohibits the use of torque wrenches or when components or modules must be quickly changed to keep down time to a minimum. SSMB/C Mating Interfaces SSMB (Snap-on) JACK PLUG SSMC (Screw-on) PLUG NOTES 1) Inside diameter of female contact to meet VSWR mating characteristics and connector durability when mated with a 0,36 - 0,38 (.014 - .015) diameter male contact. JACK 2) Must meet the force to engage and disengage when mated with its mating part.

This is the most commonly used dielectric (insulator) used in professional coaxial connectors. Push-on - See ‘‘Slide-on’’. Push-Pull - The mating engagement of latch sleeve connectors preventing accidental disengagement. Solderless SMA - An SMA connector that can be connected to semi-rigid cable by compressing the inner body rather than by soldering. (sometimes referred to as semi-rigid ‘crimp’ connectors. SSISTM - ITT Cannon range of microminiature blind-mate slide-on connectors. SSMA - A miniature version of the SMA.
