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. EPX® connectors...

DISCONNECT APPLICATIONS Specially designed for panel integration on EWIS applications, EPX® disconnect connectors cover cable-tocable and PCB-to-cable links in major commercial and business jet aircrafts. The connector can be easily identified by the locking device located directly on the connector (quarter turn device for A1 and B1 and central screws for EPXB2). This disconnect solution offers secure mating while answering OEM’s most stringent requirements, and provides: • Modularity with three shell sizes: EPXA1, EPXB1 and EPXB2 - available as lightweight shells and compatible with several...

RACK & PANEL APPLICATIONS In response to the need of system miniaturization and new equipment design, Radiall offers EPX® connector solutions for Line Replaceable Unit (LRU) and Line Replaceable Module (LRM). Discover more about these blind mate connectors: EPXB2 FOR LRU Largely used in distributed architecture, small Line Replaceable Units in an aircraft need compact, lightweight and cost-effective connectors. EPXB2 connectors equipped with centering guide will combine high density, low efforts and lightweight features. Discover the whole range of EPXB inserts offering from signal to power or...
