While it may say "5km" range for 3 different sensors,  think of it like:

3C- 5.015km
3B- 5.569km
3A- 5.922km

Generically, they all are 5km range. 

Also, if someone subgtargets your sensors with a big powerful beam and you're running a ghetto class/size that's sub-par to the size it comes with, they'll VERY QUICKLY knock your sensors out. Thus, your ability to find them easily, dock, lock destination, etc. 

Go into modules and turn your sensors off then go fight an NPC sidewinder and see what that's like. 

That's a couple reasons sensors are important.
