The HK Mi Series servos represent the next break through in high precision servo technology. Using Magnetic Induction, rather than a potentiometer, for an unsurpassed level of accuracy and performance.

Mi : Magnetic Induction, uses a magnetic rotary encoder in place of a traditional potentiometer (invented in 1877). Magnetic Rotary encoders have a longer life and suffer less wear.
