Engineered for use in any area within the aircraft, the QuickFusio™ series is the perfect connector solution for EWIS and cabin interior applications, including seat actuation systems, in-seat power supply and network, in-flight entertainment (IFE), lighting and Passenger Service Units (PSU). The QuickFusio™ series features a miniature size and offers a variety of benefits:

  • Competitive costs with the use of standard SAE-AS-38999 series II contacts
  • Versatile range with two different versions QuickFusio and QuickFusio+ covering any wiring systems due to 4 available rear outputs and 4 shell styles
  • Lightweight design with only 20 grams per pair, extreme compactness and contact density

Radiall’s experience in rectangular connectors and ability to design innovate solutions resulted in the revolutionary mechanical shape of QuickFusio, which combines the geometry of a square and a circle into an impressive compact and light weight design. Featuring a tool-less locking slide, the mating of the plug and receptacle is simple and offers the Radiall Touch: one finger mating – in a snap!

Combining high performance with quick and secure mating, this lightweight cost effective connector is the perfect solution for aerospace harsh environments.
