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 frequencies

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).
