The sensor array is a very one dimensional part. You place it down, assign crew, and it immediately becomes irrelevant in terms of management. All you need is a reactor, a crew quarters, and the sensor array... Grants additional radar range, which is all it does.
The nice thing about the Sensor Array is you can place it down and forget about it.
The problem with the Sensor Array is that the benefit it provides is really only useful in career, and even then its pretty mediocre at best, which is extending your radar/fog of war range, to be specific, visual and signature range. For visual range, it doubles it, and for signature range it increases it by ~33%.
My issue from this stems from: if its early enough that you cant take fights, then why are you spending crew and resources on this thing (its 10k which could be spent on weapons), if you're around mid game, then, again, you could be spending more crew on weapons. 6 crew is an entire HE or EMP missile launcher, and if you're late game, then it wont really make a difference and is extremely sedentary when compared to the rest of your ship.
From what I know, its pointless in PVP (which is fine since manip beams are also pointless there but are incredibly useful in career).
The point I am making is: its a very forgettable part that doesn't really add much. It's something you very much slap down to get a minimal benefit and then forget about, or something to waste crew on.
I use this thing a lot, but its because I have nothing to spend crew on when I'm memeing and mostly goof around, and I don't take career very seriously anymore.
The most I can see this being used for is playing evasively or for ships that are harvesting and can't take fights, but even then its a bit situational as why would you not stick by the harvesting ship and help it?
