Introduction Radiall is recognized in the Aerospace and Defense industries for offering one of the broadest innovative product portfolios for connector interconnect solutions. The benefit of our experience with ARINC connectors permits Radiall to provide customers with a strong and global solution. The EPX® series offers a wide range of solutions based on two insert sizes with a large variety of shells and contacts. This product range provides an excellent trade-off between the number of available contacts and the space used. The EPX® series is completely modular and expandable. The EPX®...

EPX® SERIES Our Most Important Connection is with You.™ Disconnect Application EPX® connectors (EPXA, EPXB1 and EPXB2) are specially designed to be used in cable-cable disconnect applications and PCB-cable disconnect applications. The principle of EPX® disconnect connectors is that the locking system is located on the connector itself. EPX® connectors for disconnect applications address three main needs: - Compactness: the design of the locking system allows an access from the back of the shell so that connectors can be stacked. Space can be easily saved - Modularity: connectors use similar...

Rack and Panel Application In response to the need of system miniaturization and new equipment design, Radiall introduces its new rack and panel connectors dedicated to Line Replaceable Module (LRM) applications. The EPX® rack and panel connectors are intended for blind mate applications. The plug connector is designed to be used in a Line Replaceable Module (LRM) while the receptacle is installed on the aircraft rack. There is no locking mechanism on these blind mate connectors, that feature is part of the equipment interface to the aircraft. Equipment side Radiall rack and panel modules...
