EMC Technology Florida RF Labs



Lab-Flex® Family

The Lab Flex® family of cables offer you high performance flexible cable assemblies with the lowest insertion loss and highest frequency response when compared other cables of the same diameter. They are designed with stainless steel connectors along with the strongest cable to connector termination of all the cables types. A wide range of diameters, protective coverings and electrical options are available.

The Solder Sleeve Advantage

One advantage of using Lab-Flex® cables is the cable to connector termination utilizing solder sleeves. Common methods of cable terminations such as crimping or clamping the outer cable braids to the connector body does not capture all the of the braid, which leads to intermittent electrical performance and low connector (retention) pull strength. With the Lab-Flex®  solder sleeve, both the inner and outer braid are directly soldered 360 degrees around the sleeve. This solder sleeve provides the best braid to connector termination assuring superior electrical performance and the highest connector (retention) pull strength.
