c annon's smb snap-on and smc screw-on subminiature coaxial connectors have been specifically engineered for high performance and high reliability applications in both military and commercial equipment operating at frequenciesu p to 4 ghz (smb) and 12.4 ghz (smc). the snap-on mating engagement allows a rapid connect/disconnect facility. the screw-on mating engagement allows a low vswr under vibration conditions and a matched impedance of 50 ohms. cannon smb/smc connectors are compatible with all smb/smc type connectors conforming with mil-c-39012, bs 9210, ute c93 561, ute c93 562, cecc 22 130 and cecc 22 140. in addition to this range we also offer fakra smb connectors for automotive applications. notes 1) inside diameter of female contact to meet vswr mating characteristics and connector durability when mated with a 0,48 0,53 (.019 .021) diameter male contact. 2) all undimensioned pictorial representations are for reference purposes only. 3) slide-on versions of most smb female styles, prefix 052, are available. for slide-on male interconnection use male smb (snap-on type). plug ref plane ref plane ref plane ref plane ?6,61 (.260) max ?3,71 (.146) max 1,63 (.064) 3,45 (.135) 5,95 (.234) a/f hex ?3,71 (.146) max 10-32, unf-2a jack plug jack smb (snap -on) smc (screw -on) m m a a t t i i n n g g i i n n t t e e r r f f a a c c e e s s cannon 50 ohm connectors smb / smc 19 www.ittcannon.com dimensions shown in mm (inch) specifications and dimensions subject to change key features ? rapid connect / disconnect (smb) ? standoff legs on pcb ? frequency range to 12.4 ghz (smc) or 4 ghz (smb) ? vibration withstanding design (smc)
