Lab-Flex® AF Airframe & Rugged

Lab-Flex® AF Family

Lab-Flex® AF assemblies are qualified to meet the harsh environments found in commercial and military aircraft, as well as shipboard and ground applications. Qualified to MIL-T-81490 and additional requirements found in MIL-STD-810, Lab-Flex® AF cable assemblies are constructed with a redundant water sealing system,  and have be tested and proven hermetically sealed to 1 x 10-5cm3/s. The cables also incorporate an ePTFE insulator material for the lowest loss and the outer jackets are covered with a Nomex®material for high abrasion resistance.

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 capture all the of the braid, which can lead 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 feature provides the best braid to connector termination assuring superior electrical performance and the highest connector (retention) pull strength.

Extended Boots

Our extended booting system protects the cable from kinking at the cable-to-connector termination area. This feature uses layers of different lengths and various types of shrink tubing which will distribute the force applied to the cable-to-connector termination over a 3 to 5 inch (7 to 13cm) length of cable, depending on cable diameter and length of the assembly. This method of strain relief is available on all flexible cable assemblies manufactured by Florida RF Labs.
