If the objective is to mate two panel-mounted connectors, a blade-type solution such as that seen in cordless power tools would seem a more appropriate solution.
Circular connectors are almost never used in such applications because their geometry does not readily accommodate motion between the two bodies to which each half would be attached. Without some flexibility, the connector set would likely be damaged due to shock & vibration. Such connectors with a retention mechanism are used even less frequently (if ever) in such applications for the same basic reason, but also because it’s inconvenient to reach between two closely-spaced panels to operate the mechanism.
If you’d care to elaborate a bit on the application and its requirements, we may be able to offer some better suggestions.
