Potentiometer
Encoder
Encoders typically output a digital signal.
Hall-effect
Uses a magnet to detect the rotation of a shaft.
Optical
Similar to Hall-effect encoders, but using optics instead.
Transmissive
Reflective
Analog
Produces a signal similar to a resolver. Also known as a sin-cos encoder.
Capacitive
Inductive
Resolver
Can have multiple poles. Analog signal signal output.
