dc motorIncremental encoders are the simplest and most commonly used encoder type. They are very good at feedback for speed control and can also be used for position feedback. When used as position feedback, they need to be re-homed to a reference after a loss of power. They interface to common PLC and PC controllers and are a very robust staple of industrial control.
