SMP Series Glass Sinter Connectors

SMP
The SMP series products are an ultra-small push-in RF coaxial connector with the characteristics of small size, light weight, excellent seismic resistance, wide operating frequency band, etc. The operating frequency is up to 30GHz (the high-performance SMP connectors produced by our company can reach a frequency of 40GHz). The plug has three interface forms: full escapement, semi-escapement and light hole (including with brake). When used in pairs between boards, the various interface forms can meet the axial or radial floating required for blind mating, and are suitable for occasions requiring high reliability and modular intensive installation.
