Which sensors should be used throughout the robot?

I seem to have misunderstood this sentence on the us digital website, sorry! "The S4T miniature optical shaft encoder is a non-contacting rotary to digital converter." My lack of experience with shaft encoders let me to assume that this meant the encoder literally doesn't rotate.

Encoders such as Greyhills or S4s on drive and elevators. Some teams like 10 turn pots on elevators, but I think encoders are easier. Then hall effects for indexing, or anywhere you would use a limit switch. Pots work better for arms because indexing an arm is hard. Any type of object indexing we use beam break sensors, which we buy from Adafruit. Then for shooters you either need a fast reacting beam break, or the smallest CPR encoder you can find.

Have you ever experimented with beam breaks for shooters? Any issues with programming or voltage (I've heard a few don't work below 12v?)

Note: To clarify, you mean limiting the range of something by indexing? Like using a limit switch to stop an elevator?
