QM connectors are an industry innovation to replace legacy disconnect connectors with a fast and reliable interconnect solution.


Originally developed to support Boeing 787 wire integration requirements for final assembly, the QM connector has spread to numerous applications throughout the B787 aircraft and is now used on both B777 and B747-8 platforms as well. The QM connector is considered an "enabling technology" within the Boeing Company which makes the three day plan for final assembly feasible.

With a licensing agreement between Boeing and Radiall now in place, we are pleased to be able to offer all our customers this superior product for integration applications.
