Lab-Flex® S Family

The Lab-Flex® S family is a stranded center conductor version of our popular Lab-Flex® series. They offer high flexure rates and durability over the solid center conductor designs. They are especially well-suited for test set-ups as well as Radar and Antenna systems requiring flexible coaxial interconnects that are being subjected to constant motion.  These assemblies are offered with stainless steel connectors and have the strongest cable to connector termination of all cable types.

The Solder Sleeve Advantage

One advantage of using our Lab-Flex® cables is the cable-to-connector termination utilizing our unique solder sleeves. Common methods of cable terminations such as crimping or clamping the outer cable braids to the connector body does not adequately capture all the of the braid, which can lead to intermittent electrical performance and low connector retention and pull strength. With the Lab-Flex® solder sleeve, both the inner and outer braids are directly soldered with a 360 degree coverage. This feature provides the best braid to connector termination assuring superior electrical performance and mechanical integrity.
