Cannon'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 frequencies
up 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).
