As long as everything is clean and the connectors are not deformed in any way and within specs.
And as long as you are not trying to disconnect the middle one without first disconnecting one of the outer ones. (you do not have full 40 degrees in such a configuration where you can apply all or your force.)
Really use this stuff while on a ladder, near the exhaust of a 50MW diesel engine. Or in the oil well of said motor.
I really hate it that designers only test their bullshit in clean conditions. Go out. Lay down in the oily mud (that feels and smells like cancer) below a big motor and tell me again that your device is easy to connect and disconnect while you are cooked alive fumbling with your protective gloves, not really seeing what you are doing, desperately trying to connect (or disconnect) the middle connector and wondering if you are paid enough to do this shit.
This comes from experience. A very expensive measurement device by a very well known brand had its bnc connectors way too near to each other (looked similar to your picture). They famed themselves with their device being hardened against anything you can throw at it but did forget that the user might not like the environment in such a case either. (your device at least looks like it would die before the user in such an environment.)
