Radiall QRE Connectors

Radiall QRE connector series part numbers start with the R324 prefixes

INTRODUCTION

QRE™ is a Quick-Lock Ruggedized connector. QRE™ was developed to provide the same advantages as QMA over SMA and designed more for aerospace and defense applications.

QRE™ is made of high-grade stainless-steel 316L, with Teflon coated fluorosilicone sealing o-rings which make the QRE™ interface waterproof and ultra-resistant to chemical aggression and corrosion. The outer slotted spring contact inspired by the QMA design was reinforced to provide reliable electrical contact during vibration and shock conditions. All QRE™ materials were chosen and optimized to operate within the extended temperature range typical in Mil-Aerospace applications. Its superior latching mechanism provides the advantage of a snap-on connector while ensuring a very robust and secure connection. The retention force of the interface is 3 times higher than the QMA. With similar dimensions, QRE™ offers high-density integration capabilities like QMA. In addition, a specific tool has been designed to easily disconnect QRE™ plugs on high-density applications such as active array radar modules or panels.

A limited range of straight and right-angle connectors and receptacles is available for semi-rigid and SHF high-frequency flexible cable. New connectors can be quickly developed to fit your own ruggedized coaxial cable. QRE™ cable assemblies can be delivered using our SHF airframe, lightweight or outdoor cables, with or without anti-abrasion jacket. Adapters are available for test and measurement in QRE™ to SMA and QRE™ to SMA 3.5 configurations.
