Radiall QM Connectors 

Radiall QM connectors are lightweight cable-to-cable connectors that are built to be durable in the severe operating conditions of commercial aircraft and other harsh environments. 

The QM series can be used on rails or standalone and features tool-free installation on rails and push-to-lock mating for quick and easy installation. The connectors offer high conductivity between the shells and the rail, and optional EMI backshells provide complete shielding. 

The connectors are designed for use at high altitudes, rated for high vibration and shock, and can withstand 3.6kA lighting strikes. Radiall offers the QM series in size A and size B variants.

Both sizes use the same range of contacts and rails, with size A offering 40% weight savings compared to size B.
