SMB Connector Specifications


Standard Coaxicom SMB, SMC and CMS connectors are subminiature 50 Ohm connectors that have widespread application in telecommunications, GPS, PC/LAN and military applications. The SMB series features Snap-On mating, while the SMC has a threaded coupling to provide higher reliability in vibration-prone environments. The CMS is similar to the SMB, but has no detent. Connectors for cable groups 22, 25, and 27 are available in crimp style only. CMS plus will mate with SMB jacks.
Mini-SMB 75 Ohm connectors as well as mating printed wiring board connectors are available for 75 Ohm miniature cables such as RG179 and RG187. These connectors are t he same size as standard 50 Ohm connectors and are intermatable with them as well. To specify a 75 Ohm SMB, add suffix “-75” to a 50 Ohm part number.

The Coaxicom subminiature connector series can be mated with a side variety of other connector series through our precision RF adapters. The subminiature series is also designed to work with flexible, semi-rigid and ultra-flex coaxial cables.
