Cannon 50 Ohm Connectors SMB / SMC 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. Key Features 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. * Rapid connect / disconnect (SMB) * Standoff legs on PCB * Frequency range to 12.4 GHz (SMC) or 4 GHz (SMB) * Vibration withstanding design (SMC) In addition to this range we also offer FAKRA SMB connectors for automotive applications.
