SMA Coaxial Connectors and  

Sub Miniature Coaxial Connectors

(   Standards : MIL-C-39012   )

Our sub miniature connector series are coaxial connectors manufactured in the SMA style meeting MIL-C-39012 specification.
It is a 50 ohm super miniature with excellent high frequency capabilities when used for telecommunications. It is most suitable in cases where space is limited and solid reliability is required. It can be combined with a screw on system and can use flexible cable and semi-rigid cable. There a re two types of cable connectors, crimp and clamp.
