TFOCA GenX/InfiniBeam Flexdapter


Corning’s Flexdapter™ flexible interface adapter is designed to assist in the transition of legacy interconnect solutions to the latest technology available. In the pictured configuration, the

Flexdapter is configured to support connection of a MIL-PRF-83526/20 Expanded Beam connector to a legacy physical contact TFOCA GenX tactical plug or receptacle. This flexible design solves a common issue found with solid adapters of excessive overall length in cramped quarters and/or resulting moment arm aggravated poor vibration and mechanical shock performance of connectors mounted on mobile platforms. By incorporating a multidirectional flexible section, the Flexdapter can be set to any desired angle and rotation. This all but eliminates the added length and moment arm concerns associated with solid adapters. Built to withstand the rigors of military tactical use, the Flexdaptor provides tensile cable retention of up to 150 lbs.
