QM Connectors

Radiall Quick Multipin (QM) connectors are designed for use with in-line disconnect applications on commercial airplanes. Radiall QM Connectors provide long-lasting durability needed for the severe environments encountered by aerospace applications. These connectors offer a -65°C to +155°C operating temperature range, 1000 hours at 155°C temperature life, and 50,000 feet altitude immersion. QM also provides 13.8grms vibration, 50g shock, and 3.6kA lightning strike characteristics. QM comes in Size A and Size B connectors that are mounted on the same range of rails. Size A is designed to save weight and space when a smaller insert with fewer contacts can be used in the wiring design.
