SMA s/o
RF Coaxial Connectors
SMA Slide-On Plug
Introduction
The SMA Slide-On Plug is designed to fill the need
of components and systems manufacturers, for a
reliable, fast method of testing.
They completely eliminate the need for torquing
and yet provide absolutely comparable electrical
performance with no wear and tear on threads of
unit under test.
These units mate with standard SMA jack
connectors.
